Here's an easy trick to add moistness to your baked goods: add a little Greek yogurt. This recipe from Chobani Greek Yogurt adds it to a mixture of flour, eggs, sugar, and apple pie spice for unique and fruity carrot muffins.
Preheat the oven to 375 degrees.
Mix together the flour, sugar, baking powder, apple pie spice, baking soda, and salt.
In a food processor, pulse the yogurt, carrots, eggs, oil, and vanilla. Mix into the flour mixture, then stir in the raisins.
Divide the batter among a greased or paper cup-lined 12 cup muffin tin. Bake until golden-brown, about 25-28 minutes.
