Light and moist, these applesauce muffins are easy and delicious! They're packed with brown sugar, cinnamon, and unsweetened applesauce, topped with extra sugar for a crunchy finish.
Prep. Preheat the oven to 375°F. Line a 12-cup muffin tin with paper liners. Set aside.
Make the batter. Combine the butter and sugar in a bowl. Beat with a hand-held mixer until the sugar is dissolved. Add the applesauce and vanilla extract and stir to combine. Add the eggs, one at a time, and beat well with the hand mixer after each addition.
Add the dry ingredients. Stir in the flour, baking powder, cinnamon, and nutmeg into the butter-egg mixture. Stir until just combined.
Bake the muffins. Divide the muffin batter between the paper liners, filling each up to ¾ full. Top the muffin batter with brown sugar. Bake the muffins for 20-22 minutes or until a toothpick inserted in the center comes out clean.
Cool. Remove the muffins from the oven and let them cool for 5 minutes in the muffin pan, then transfer them to a wire rack to cool completely.
