Step 1

Preheat the oven to 375 degrees F and grease 10 cups of a standard-size muffin tin.

Step 2

Place the oats into a food processor or blender. Grind for about 30 seconds or until they resemble a coarse flour.

Step 3

Add the rest of the ingredients except the chocolate chips, if using.

Step 4

Blend until very smooth, stopping to scrape down the sides of the blender if needed.

Step 5

Divide among 10 muffin cups. You want each cup to be about 3/4 full. Top with chocolate chips if using.

Step 6

Bake for 20-22 minutes or until firm to the touch and lightly golden brown around the edges. Let cool in the pan for 5-10 minutes, then transfer to a wire rack (or just tilt a bit in the pan to let air flow underneath) to cool.

Step 7

Serve warm, at room temperature, or chilled.
