In a large mixing bowl, combine the cornmeal, whole wheat pastry flour, all-purpose flour, baking powder, sugar and salt in a large bowl. In a separate bowl, mix together the milk, eggs, applesauce, and melted, cooled butter.
Slowly pour the wet ingredients into the dry ingredients, and stir with a wooden spoon, until they are just blended. Do not over mix. Allow the mixture to rest at room temperature for 20 minutes.
Meanwhile, preheat the oven to 350 degrees F. Line a 12-cup muffin tin with paper liners or lightly grease with cooking spray. Spoon the batter into the tin, filling each one just to the top.
Bake the corn muffins for 23-25 minutes, until the tops are lightly crisp and a toothpick inserted in the center comes out clean. Let cool for 5 minutes in the pan, then gently transfer to a wire rack to cool completely...or enjoy them warm right away.
RECIPE VARIATION: I originally shared this muffin recipe with a jam filling. After the muffins cool, spoon 3/4 cup seedless raspberry preserves into a pastry bag fitted with a large round tip. Push the tip into the top of the muffin and squeeze 1-2 tablespoons of jam into the center, until you fear it may burst. Repeat for each muffin.
TO STORE: Leftover muffins will keep well in an airtight container at room temperature for up to 2 days.
TO FREEZE: Place muffins in a single layer on a baking sheet and freeze until solid. Transfer the frozen muffins to an airtight freezer-safe storage container or ziptop bag for up to 3 months. Thaw and enjoy as desired.
