Preheat the oven to 350 F. Prepare a silicone cupcake tray or grease/line a standard cupcake tray.
In a large mixing bowl or bowl of a stand mixer, combine the dry ingredients: gluten free flour, brown sugar, baking soda, baking powder, and salt. Mix until combined.
Add in the wet ingredients: eggs, Greek yogurt, milk, melted butter, and vanilla extract. Beat until just combined.
Fold in the chocolate chips.
Allow the batter to rest for 10 minutes.
Scoop the muffin batter into the prepared cupcake tray until the cups are ⅔ of the way full. I used a cookie scoop.
Bake until lightly browned on top and a toothpick inserted in the center comes out clean, about 20-25 minutes. Since oven temperatures vary, keep an eye on your muffins as they bake so they don't overcook.
Allow the muffins to cool in the pan for 5-10 minutes before placing onto a wire cooling rack. Allow the muffins to cool completely before storing.
Enjoy!
Notes
Store gluten free muffins in an airtight container at room temperature and enjoy within 2 to 3 days. You can also freeze these muffins. Once ready to eat, remove from the freezer and let sit at room temperature for 30 minutes. Warm in the microwave for 10-20 seconds to soften.
