Step 1

Preheat oven to 375 degrees. Line a 12-cup muffin pan with foil baking cups, or spray it with nonstick spray.

Step 2

In a blender, pulse oats to the consistency of coarse flour. Add all remaining ingredients except blueberries. Blend until smooth and uniform, stopping and stirring if needed. (Do not over-blend.)

Step 3

Distribute mixture among the muffin cups, and smooth out the surfaces. Top with blueberries, and lightly press to adhere.

Step 4

Bake until a toothpick inserted into the center of a muffin comes out clean, 18 - 20 minutes.
