Prepare pan: Preheat oven to 340ºF (170ºC). Line a 12-hole muffin tin with paper cups and set aside.
Melt butter: Melt the butter and set aside to cool slightly while preparing the batter.
Mix dry: In a large mixing bowl, whisk together the flour, sugar, baking powder, baking soda and salt.
Add wet ingredients: Pour in the melted butter, applesauce, beaten egg and vanilla. Fold gently with a spatula until just combined, do not over-mix.
Add chocolate chips: Stir through the chocolate chips until evenly distributed.
Fill tin: Spoon the batter into the muffin cups, filling each about ¾ full. Tip: Use a small cookie scoop for even portions.
Bake: Bake for 18–20 minutes or until lightly golden and a toothpick inserted in the center comes out clean.
Cool: Let muffins cool in the tin for 5 minutes, then transfer to a wire rack to cool completely. Enjoy!
