Flowers wilt. Boxes of chocolates have their duds. Men forget to make dinner reservations. But a gooey, molten chocolate cake in a mug that cooks in 90 seconds and tastes like a fancy molten lava cake that you’d get in a restaurant?

Love to last a lifetime!

Chocolate Mug Cake, you get me.

Now, I am not going to pretend for one second that I invented the concept of chocolate mug cake or that today’s chocolate mug cake recipe is my first time making it.

In fact, if you are willing to extend the definition of “mug” to include “tiny pink plastic container with matching tiny pink spatula,” I’ve probably been making chocolate mug cake since the day Santa brought me my beloved Easy Bake Oven.

If you’ve never had Chocolate Mug Cake, please allow me to introduce you to what will surely become one of the most delicious, dangerous recipe concepts to grace your kitchen.

To make Chocolate Mug Cake, stir all the ingredients together in a coffee mug, pop said mug in the microwave, and BOOM!

Best Chocolate Mug Cake! This easy, gooey chocolate mug cake is the perfect single-serving dessert. Lightened up with healthy ingredients such as Greek yogurt, peanut butter, and dark chocolate.

Seconds later, you have a mug of molten chocolate cake, ready to be topped with vanilla ice cream, sprinkles, more chocolate, whipped cream…or eaten triumphantly just as it is.

The Miracle of Chocolate Mug Cake

What makes this particular Chocolate Mug Cake recipe stand out among the rest is its lineup of ingredients. I dropped the excess butter, oil, and refined sugar you’ll find in most chocolate mug cake and chocolate mug brownie recipes for a healthier lineup: whole wheat flour, peanut butter, Greek yogurt, maple syrup, and, of course, plenty of dark chocolate.

Despite its more healthy ingredients, I promise you this gooey Chocolate Mug Cake delivers. It’s molten and almost pudding-like in the center, and the edges are fudgy and moist. It takes less than five minutes from start to finish, making it the best Valentine’s Day present I could ever hope to give you.

The next time you are craving something sweet but don’t want to commit to an entire Flourless Chocolate Torte or Chocolate Mousse Pie, this perfectly portioned, easy chocolate cake in a mug will be waiting right here for you.

Gooey Chocolate Mug Cake. This molten chocolate cake in a mug is what dessert dreams are made of! Made in just 90 seconds in the microwave, this treat is healthy, easy, chocolatey, and perfect for Valentine's Day.

With whomever and however you celebrate this V-Day, I hope this easy Chocolate Mug Cake adds sweetness to your day. It’s probably big enough to share, but on this day of chocolate, I’d say we each deserve a molten Chocolate Mug Cake of our very own. Happy Valentine’s Day!

Chocolate Mug Cake

This Healthy Chocolate Mug Cake is INCREDIBLE! Easy and ultra moist with a molten, gooey center. Made with peanut butter, Greek yogurt, and dark chocolate, this lighter version of chocolate cake in a mug cooks in just 90 seconds in the microwave.

Yield: 1 extra-large serving

Prep Time: 2 minutes

Cook Time: 1 minute

Total Time: 6 minutes

Ingredients:

  • 2 tablespoons white whole wheat flour (or GF 1:1 All Purpose Baking Blend)
  • 2 tablespoons unsweetened cocoa powder
  • 1/4 teaspoon baking powder
  • 1/8 teaspoon kosher salt (a good pinch)
  • 3 tablespoons milk, any kind you like (I used unsweetened almond milk)
  • 2 tablespoons nonfat plain Greek yogurt (use nondairy yogurt to make dairy free; I haven’t tried mashed banana or unsweetened applesauce but think this could work too)
  • 1 1/2 tablespoons pure maple syrup
  • 1 tablespoon peanut butter, almond butter, or other nut butter of choice
  • 2 tablespoons dark or semisweet chocolate chips (for an extra fudgy cake, add 1 additional tablespoon)
  • Optional toppings for serving: vanilla frozen yogurt, nonfat vanilla Greek yogurt, whipped cream, extra chocolate chips, a dollop of extra nut butter

Directions:

  1. In the bottom of a 12-ounce microwave-safe mug, stir together the flour, cocoa powder, baking powder, and salt. Add the milk, Greek yogurt, maple syrup, and almond butter. With a fork, stir until smoothly combined. Stir in the chocolate chips.
  2. Place the mug on a paper towel in the microwave to catch any drips. Microwave on HIGH for 90 seconds, just until a toothpick inserted near the edge comes out with a few moist crumbs clinging to it. The center will be batter-like and molten. Do not over microwave or the cake will be dry. It may take a little experimenting, depending upon the power of your microwave and width of your mug. Wider mugs will cook more quickly, while taller, narrower mugs may need a little more time. Let cool at least 3 full minutes (the cake will continue to cook a bit as it cools, and the cake will be very hot). Add any desired toppings. DEVOUR.
  • The exact cook time of the chocolate mug cake may vary based on the power of your microwave. Mine is 1000 watts. It will also vary based on your coffee mug. Taller, narrower mugs may need a bit more time, while wider mugs may need less. (I developed the recipe in this 12-ounce coffee mug).
  • Microwave mug cakes are meant to be enjoyed the day they are made, so I cannot offer tips for leftovers. You could try reheating any leftovers in the microwave, but I think the cake would dry out, so at that point, I’d recommend embracing the easiness of this recipe and making a fresh one.

  1. I love mug cakes and this one sounds great – can’t wait to try it out soon!

  2. This cake looks like it would be good. But, after reading the nutrition information, how is this described as being healthy?

    • Hi! It’s definitely still dessert and a treat, but the recipe features healthier swaps for traditional mug cake ingredients, such as Greek yogurt, peanut butter, no refined sugar, and whole wheat flour. Everything in moderation!

  3. Thank you, thank you, Erin, for making this more healthy for us! With the Greek yogurt and maple syrup, I am so very eager to try this! I don’t have white whole wheat flour on hand; I’m guessing regular flour will be okay?

  4. I’ve never seen the hype about mug cake, but this looks pretty fool-proof! I agree with ‘everything in moderation’ and this definitely makes for that definition.

  5. I simply love mug cakes, but I’ve always done the store-bought kind, never made them myself. I can’t wait to try this recipe, must be delicious!

  6. So gooood!!! Thank you for this amazing mug cake! Being 4 months pregnant sometimes you just NEED SOMETHING,but I try to stay away from anything too processed. This is perfect! Super yummy! Super easy! And SUPER FAST! I love your blog!!!

  7. AMAZING!! I always crave sweet gooey chocolately goodness (even more so now that I’m a breastfeeding mom!), and this totally hit the mark, like better than a “real” giant cupcake but so much better for you (yes, it’s got some calories but not too processed and has some protein). Confession – I made one of these every day for the past week. So, then I started riffing on it. Erin, if you can perfect a recipe for a lemon ricotta honey mug cake, please post!

    • Laurel, this comment made my day!!! I feel the same way about it: Definitely a treat, but I love that it’s less processed (and so chocolaty!). The honey ricotta idea sounds to die for. Definitely filing that one away for future inspiration. Thank you!

  8. MAJOR CHOCOLATE without being too rich, sweet or dense. Yum. I like the peanut butter in it.

    • Sarah, I’m so glad you enjoyed it. (MAJOR CHOCOLATE is the perfect description!) Thank you for reporting back!!

  9. I can’t believe how good this mug cake is since most of the ingredients are healthy! Perfect treat the end the day! I used peanut butter and absolutely loved it!
