I could not stop grinning the entire time I was baking, decorating, photographing, and, best of all, eating this American fruit Flag Cake. If I had any idea how much of a joy it would be to transform a fluffy yellow sheet cake into a patriotic Fourth of July dessert, I would have written Flag Cake at the top of my summer bucket list. If you are looking for further evidence that we are never ever too old to have fun with our food, this would be it.

Now, before I go on and tell you why of all the fruit flag cake recipes in the universe you should make this particular flag cake, let me clear up one tiny point: I did not invent flag cake.
While I aspire to that level of culinary adorableness, I’ve never been particularly adept at fancy desserts or anything bordering on “theme” food.
Dear future parents of my hypothetical children’s classmates: please do not judge my children for their mother’s pitiful lack of décor at their birthday parties. The party may not have a theme, a cake in the shape of a dinosaur or Disney princess, or any semblance of order, but we will have sangria. I trust you can forgive.
Or maybe we’ll have Flag Cake, because SO CUTE. And so delicious. And so, so easy.
“Fourth of July” is an acceptable party theme for ages 1 to 17, is it not?
Or, here is an even better idea: let’s all make Flag Cake for the actual Fourth of July!

Although I’ve seen dozens of different recipes for Flag Cake—Jello, poke, and Cool Whip being three of the most common descriptors—every one of them seemed too heavy or even artificial to be a worthy sweet finale to a special summer barbecue.
Maybe I walked by this shirt too many times at Target, or maybe I have some culinary cuteness buried inside of me after all, but I became fixated on the idea of coming up with a healthier Flag Cake recipe.
I craved a better cake than what Pinterest promised. I wanted it to be made from wholesome ingredients, and I wanted it to taste rich and indulgent enough to be a true crowd pleaser no matter where I served it.

About This Flag Cake
After a few recipe attempts, this Flag Cake recipe is where I landed. The fluffy yellow sheet cake base is made with whole wheat flour and sweetened with honey, and part of the butter has been swapped for Greek yogurt.
The cream cheese frosting includes Greek yogurt also and isn’t overpoweringly sweet so that the flavor of the fresh berries can shine.
The Flag Cake is still on decadent side (I kept enough butter and sugar to make it taste like a real cake and not a flag muffin), but in comparison to most other flag cake recipes you’ll find, it leaves you the most wiggle room to serve yourself an extra-large slice, thank goodness. Extra large is the size you are going to want!

With its no-fuss sheet cake style, this Flag Cake is ideal for transporting to parties and slicing to serve a crowd. After diving into a piece of the cake myself, I gave a generous serving to our painter.
I thought he’d take it home, but he stood in my kitchen and quietly inhaled the entire thing in approximately 30 seconds.
The rest of the Flag Cake was gifted to friends who had company in town to enjoy it and who are accustomed enough to my blog leftovers not to mind a missing slice or two. They immediately texted to say the cake had been a hit and could I please send them the recipe early.
No one suspected this Flag Cake had been lightened up, and I guaranteed your party won’t either!
Make Ahead and Storage Tips
- To Make Ahead. Cake can be made 1 day in advance, covered tightly at room temperature, and then frosted before serving. Frosting can also be made 1 day ahead of time and stored in an airtight container in the refrigerator. Let come to room temperature for easier frosting of the cake.
- To Store. Store leftovers in the refrigerator, tightly covered, for up to 3 days.
- To Freeze. You can also remove the fruit and store for up to 5 days in the refrigerator or freeze for up to 3 months.
Recommended Tools to Make This Recipe
- Baker’s half sheet pan (my favorite pan ever!)
- Offset spatula (ideal for smoothing both the cake batter and frosting)
Flag Cake
Ingredients
For the Flag Cake:
- 1/2 cup unsalted butter softened to room temperature (1 stick)
- 1 cup granulated sugar
- 1/2 cup honey
- 2 large eggs at room temperature
- 2 teaspoons vanilla extract
- 3/4 cup nonfat plain Greek yogurt at room temperature
- 1 1/4 cups white whole wheat flour*
- 1 cup all-purpose flour
- 1 teaspoon baking soda
- 1/2 teaspoon kosher salt
- 3/4 cup milk plus 2 tablespoons—any kind you like—I used 2%, at room temperature
For the Frosting and Decoration:
- 12 ounces reduced-fat cream cheese Neufchatel, at room temperature
- 6 tablespoons unsalted butter at room temperature
- 1 1/3 cups powdered sugar
- 1/4 cup nonfat plain Greek yogurt at room temperature
- 1 teaspoon pure vanilla extract
- 1 cup fresh blueberries
- 2-3 cups sliced fresh strawberries
Instructions
- Preheat the oven to 325 degrees F. Generously grease and lightly flour an 11×17-inch half-sheet pan or coat with baking spray (the floured kind, like this). Set aside.
- In the bowl of a stand mixer fitted with the paddle attachment or a large bowl with a hand mixer or spoon, cream the butter for 1 minute on medium speed, until it is smooth and creamy. Add the sugar on medium speed and beat until fluffy and light in color. Beat in the honey, then the eggs and vanilla until smooth and nicely combined, stopping to scrape down the sides and bottom of the bowl a few times. The mixture may look curdled. Beat in the yogurt on medium-high speed until blended.
- In a large bowl, whisk together the whole wheat flour, all-purpose flour, baking soda, and salt. Pour one-third of the flour mixture into the butter mixture. Beat on low speed for 5 seconds, then pour in half of the milk. Beat on low speed for 5 seconds. Repeat with the next third of the flour, then the remaining half of the milk. Add the last third of the flour and beat just until combined and the batter is smooth. Do not overmix.
- Spread the cake batter into the prepared pan, smoothing it into a thin, even layer with a rubber spatula or offset spatula. Bake for 18 to 22 minutes or until the top is lightly browned and a toothpick inserted in the center comes out clean, rotating the pan 180 degrees once halfway through.
- Place the baked cake on a wire rack and let cool in the pan completely. Meanwhile, make the frosting.
- For the frosting: In the bowl of a stand mixer fitted with the paddle attachment or a large bowl with a hand mixer or spoon, beat the cream cheese, butter, powdered sugar, yogurt, and vanilla on medium speed until smooth and combined.
- Spread the frosting over the cooled cake. Arrange blueberries in rows in top left corner to form the “star” portion of the flag. Line the strawberry slices in 5 rows to form the “stripes.” Refrigerate until ready to serve.
Notes
- *You can substitute the same amount of all-purpose flour for the 1 1/4 cups white whole wheat flour. If you make this swap, reduce the amount of milk in the recipe to 3/4 cup plus 1 tablespoon.
- Cake can be made 1 day in advance, covered tightly at room temperature, and then frosted before serving. Frosting can also be made 1 day ahead of time and stored in an airtight container in the refrigerator. Let come to room temperature for easier frosting of the cake.
- Store leftovers in the refrigerator, tightly covered, for up to 3 days. You can also remove the fruit and store for up to 5 days in the refrigerator or freeze for up to 3 months.

Yum! I love all things themed, and last year I made flag brownies!! :) This looks PERFECT for 4th of July!
Flag brownies sound equally delicious, Tara!
Hi Erin!
This looks amazing, but I’m gluten free. Any thoughts on how to go about subbing the flour for either almond or coconut flour? Would that still taste just as good?
Thank you!
Cait
Hi Cait, generally you can never swap almond flour or coconut flour for all-purpose, because they have such different properties. This is definitely something where you’d want to use a gluten-free all-purpose flour blend instead. I like the Bob’s Red Mill one! I hope you love it if you give the recipe a try!
This cake is so beautiful! It will be great for me to make on our 4th of July wedding anniversary! Wish I lived nearby and could be a recipient of your blog leftovers! Thanks, Erin!
Thanks so much, Laurie! I hope you enjoy it for your special celebration!
This is adorable, Erin! I’d say you have some cuteness buried in there somewhere. :) And the strawberry stripes, especially, look beautiful! Yum!
Thanks so much Melissa! :)
It’s so beautiful and I just loved it. *applause*
Loved the cake. Only disappointment, here in Fl. almost impossible to find boxes of strawberries
close
to the same size . By July they are huge with a mixture of sizes. However many compliments for the
slices
given. (they didn’t see the entire cake before being served).
Dee, I’m so happy to hear you enjoyed the cake! Thanks so much for taking the time to report back!
Can I make this in a 13×9″ pan?
Lauren, you could experiment, though it will change the baking time. I’d fill the pan about 3/4 of the way full, then keep an eye on the cake. If you have extra batter, you can bake it as cupcakes. I hope you love the recipe!
We made this for the Fourth and everyone LOVED it! It looked beautiful and the texture was so light and fluffy. Thanks for the recipe!
Sandra, I am so pleased to hear this! Thank you for letting me know and Happy 4th!
Made this for the fourth and my friends loved it. I was hoping for leftovers but there werent any. Going to be a new tradition for us!
Billie, no leftovers is the best sign! Thanks for trying the recipe and sharing this lovely review!
My sister is turning 80 on the 4th of July! Neither of us can believe that! Until I moved away, every year I was elected to make a patriotic dessert for about 25 people. It’s been many years since I’ve done it, but your cake brings back such wonderful memories! I live at high altitude now, so will have to try the recipe with a few tweaks. Thank you for always giving me a brilliant idea for something that makes me look good to my husband! I love your post about the cake, it’s so cute and funny. Have a wonderful Fourth of July!
I hope you enjoy the cake if you try it, Peggy! Thank you for sharing this kind comment!
Hi! This looks great! I don’t have wheat flour and was wondering if I can use all purpose flour only? Thank you!
Definitely Liz. I hope you love it!
Can I sub sugar for the honey?
Megan, you do need a liquid sweetener for the correct texture. Pure maple syrup would work!
Great and tasty recipe – I loved that it has yogurt and honey :)
I am so happy to hear how much you enjoyed it Erin!
How do you keep the juices from the strawberries from getting on the white icing?
Emily, you can pat them dry first if you like!
My family and I loved this recipe! Super easy and fun to make.
I’m so happy that you enjoyed it, Hannah! Thank you for sharing this kind review!
Erin, this cake is amazing! I will make it again, and again for other occasions and maybe try some different fruits on it. I would not change a thing. I love that it is in a sheet pan and is a thin layer of cake. I also used a bit less frosting since the cake is so delicious I didn’t want to hide it. Thanks as always! This one is a winner!!!
I’m so happy that you enjoyed the cake, Donna! Thank you for sharing this kind review!
Made it last weekend and loved it! So yummy! Everyone liked it too :)
I’m so happy that you enjoyed it, Jane! Thank you for sharing this kind review!
Hi, I don’t know why this recipe came up when I searched for vegan flag cake, however I like what I see so far…Ever made a eggless version so far? Anyone?
Hi Nikki! I’ve never tried this recipe without eggs, so it would be a complete experiment. If you decide to play around with it, I’d love to hear how it goes!
I love it !!! Whats recipe for itt?
Hi Lorra, you will find the recipe in the recipe card! Hope that helps!
This cake is delicious! Moist and rich and the frosting is a perfect topping with the berries. Most guests had second servings and raved about how good it was. I made in a 9×13” pan so baking times was 12 minutes longer.
Thank you Erin❣️
Hi Marianne! Thank you for the feedback! So glad you enjoyed it! Thank you for this kind review!
The description she gives of this cake recipe is spot on! I found it to be moist, rich and decadent, and everyone in my house thought it was a huge hit! The icing is phenomenal also. I believe it’s true no one would suspect it to be a lightened up version. I used entirely AP flour and reduced the amount of milk as is indicated in her notes. If you try this, you will be making this many times for years to come!
Hi Rebecca! So glad you enjoy the recipe! Thank you for this kind review!
So festive! Can’t wait to make this!
I hope you enjoy it, Danielle!
This looks amazing! I am pinning it for next year. Quick question though: can I use full-fat greek yogurt?
Hi Jessica! You sure can!
Hi can we double the layers ?
I am making this cake for my in-laws who just became US Citizens
Hi Sehzad! There is a button in the recipe card that will help you convert the ingredients. It says 1x, 2x, 3x. Sometimes it does not always work properly so I would double check each ingredient as you are making it. Hope you enjoy it!
I also made it with all AP flour, as the poster below mentioned doing. The cake was delicious. In case anyone is interested, I evenly divided the batter between two disposable 9×13 pans, then carefully removed the thin baked and cooled cakes onto their own platters to decorate, surrounding the sides with chopped blueberries and strawberries (I had a lot of strawberry pieces left from trying to make nice slices for the top!), which provided more fruit per serving. I would absolutely make this again.
Thank you so much for sharing, Happy Fourth!!!!
This cake is pretty cute. I used to make a version as a kid but this is more interesting with the cream cheese and honey. I would probably cut the sugar and honey in half. We did half the honey and it was still a little sweet for me. We also added cream to the frosting while whipping to make it less dense. Just a personal preference and we had the cream on hand. I would add some lemon or lemon zest to the frosting next time to brighten. My 7 yo daughter and I loved making it together.
Hi Sasha! So glad you enjoyed the recipe! Thank you for this kind review!
Delicious! It’s not a fluffy cake but more dense, deliciousness with hints of honey and a tad more healthy with whole wheat flour! Will keep for next year! The flag decor was a hit!
Hi Sunflower! So glad you enjoyed the recipe! Thank you for this kind review!
