Ingredients

2 and ⅓ cups oat flour*
½ cup coconut sugar or brown sugar
⅓ cups cornstarch
2 teaspoons baking powder
½ teaspoon baking soda
½ teaspoon salt
½ teaspoon cinnamon optional
2 large eggs
⅔ cup Greek yogurt regular or vanilla, I use vanilla
⅓ cup olive oil canola or vegetable oil works too
⅔ cup milk any type
2 teaspoons vanilla extract
1 cup mix-ins* I used dark chocolate chips

Instructions

Preheat the oven to 375ºF and position the rack in the center of the oven. Line a standard 12-cup muffin tin with paper liners and spray the liners with non-stick spray.
Whisk the oat flour, coconut sugar, cornstarch, baking powder, baking soda, salt, and cinnamon in a large mixing bowl. Set aside.
In a separate bowl, whisk together the eggs, yogurt, olive oil, milk, and vanilla extract until smooth.
Pour the wet mixture into the dry mixture and stir with a large spoon or spatula until everything is well incorporated. Fold in your mix-in (I use chocolate chips).
Distribute the batter evenly among the 12 muffin cups (a cookie scoop works well for this). Sprinkle with turbinado sugar (sugar in the raw) if desired. Bake for 14-16 minutes or until a toothpick inserted into the center of a muffin comes out clean (or with a few moist crumbs).
Allow the muffins to cool in the pan for 5 minutes before transferring them to a wire rack to cool completely.

Notes

Oat Flour- Oat flour is sold in stores, but it’s also super easy to make at home. Simply blend old-fashioned oats in a high-speed blender until the oats become a fine powder (about 30 seconds to a minute). Store your oat flour in an air-tight container for up to three months. For more tips on baking with oat flour, see my oat flour guide.

Mix-Ins- Chocolate chips, blueberries, chopped apples, nuts, cranberries… whatever makes you happy.

Storage- Store your muffins covered at room temperature for 2-3 days or in the refrigerator for up to a week.
