Instructions
Preheat oven to 425 F. Line muffin tin with baking liners. Grease with nonstick spray and set aside.
In a medium bowl, combine the gluten free flour, baking powder, salt, cinnamon. Mix until combined.
In a separate bowl, combine the softened butter and sugar. Beat with an electric mixer until soft and creamy, about 2 minutes.
Add the eggs, vanilla, milk and lemon juice. Beat until mixed.
Add the flour mixture to the butter mixture. Mix just until combined.
Cut the blackberries in half, rinse under water and pat dry to remove excess juice.
Mix the blackberries in with a spoon, careful not to break them.
Fill the muffin tins all the way to the top. Bake in the over for 25 minutes, or until the center comes out clean with a toothpick.
Notes
Gluten free flour: use a gluten free flour with a 1:1 baking ratio. It must contain xanthan gum. This is my favorite gluten free flour.Measure the flour carefully. Spoon it into a measuring cup and level it off with a knife. Don’t scoop flour right out of the bag, as this will pack the measuring cup too full and make dry muffins.Fill the muffin cups to the rims to create a tall muffin. Use eggs that are at room temperature. Let them sit out 30 minutes before using.
