Preheat oven to 400°F. Grease a mini-muffin tin.

Put all of the ingredients into a blender and pulse until smooth. You may need to use a spatula to scrape down the sides of the blender so that everything gets blended well. At this point you can store the batter in the refrigerator for up to a week.

Bake in the oven for 15-20 minutes, until all puffy and just lightly browned. Remove from oven and let cool on a rack for a few minutes.
