Instructions
Prep:
Preheat oven to 350 degrees and line a muffin pan with 12 paper liners.
In a small bowl, combine the brown sugar and cinnamon, set aside.
Make the batter:
In a large bowl or the bowl of your stand mixer, beat the sugar and butter until smooth and creamy. Add in eggs, 1 at a time, and mix until incorporated; add vanilla extract.
In another bowl, sift the flour and baking powder together.
Add the flour mixture slowly to the butter-sugar bowl and combine. Add in the milk and mix until the batter is smooth.
Fill the muffin tin:
Fill each muffin cup with about 2 tablespoons of batter (halfway full) then distribute the apple pieces between the muffin cup. Top with additional batter, about another 1-2 tablespoons, covering the apples.
Top each muffin with ½ to 1 teaspoon of the brown sugar mixture. Using the back of a fork, gently swirl brown sugar and cinnamon mixture into the muffin batter.
Bake:
Bake the muffins in the preheated oven for 22 minutes or until golden brown and a toothpick inserted in the center comes out clean.
Remove from oven and allow to cool for 10 minutes before removing from the pan and serving.
Notes
The type of flour mix you use will make a big difference. I have tried this recipe with King Arthur Flour All Purpose Gluten-Free Flour, King Arthur Flour All Purpose Gluten Free Baking Flour, Cup4Cup (blue bag), Pamela's Gluten Free Baking Mix (orange bag), Pamela's All-Purpose Gluten Free Flour Mix (blueish/purple bag), Namaste Gluten-Free Perfect Flour Blend.
Please note that if you make your own mix you must make sure you add xanthan gum to help bind your flour starches together (the mixes above already have it). I can't advise on other blends since I haven't tried it. If you use another mix successfully, please leave a comment for others to read.
