Ingredients

Servings 12

1 1/2 cups whole wheat pastry flour
1 teaspoon baking powder
1/2 teaspoon baking soda
1/2 teaspoon ground cinnamon
1/4 teaspoon salt
1/2 cup pure maple syrup
1/3 cup unsweetened applesauce
1/4 cup low-fat plain yogurt
2 large eggs
1 teaspoon vanilla extract
1/2 cup finely chopped walnuts
For the Cinnamon Swirl Frosting
1/2 cup unsalted butter, softened
1 1/2 cups powdered sugar, sifted
1 teaspoon vanilla extract
1/2 teaspoon ground cinnamon
2-3 tablespoons low-fat milk (or as needed)

Instructions

Preheat the oven to 350 degrees F (175 degrees C). Line a 12-cup muffin tin with paper cupcake liners.
In a large mixing bowl, whisk together the whole wheat pastry flour, baking powder, baking soda, cinnamon, and salt until evenly combined.
Add the maple syrup, applesauce, yogurt, eggs, and vanilla extract to the dry ingredients.
Stir gently with a wooden spoon or spatula just until the flour disappears. Avoid overmixing so the whole-grain cupcakes stay tender.
Fold in the finely chopped walnuts until evenly distributed.
Divide the batter among the liners, filling each cup about two-thirds full.
Bake for 18 to 20 minutes, until the tops spring back lightly and a toothpick inserted in the center comes out clean or with a few moist crumbs.
Cool the cupcakes in the pan for 5 minutes, then transfer them to a wire rack to cool completely before frosting.
For the frosting, beat the softened butter until creamy. Gradually beat in the sifted powdered sugar, then mix in the vanilla extract and cinnamon.
Add the milk one tablespoon at a time until the frosting is smooth and spreadable.
For a cinnamon swirl effect, place part of the frosting in a second bowl, add an extra pinch of cinnamon, then loosely swirl the two frostings together with a knife or toothpick.
Spread or pipe the cinnamon swirl frosting onto the fully cooled cupcakes.
