To halve the recipe, halve the oats, the banana, and the milk. Keep everything else the same. You can either use 6-oz or 8-oz ramekins.
Use a high-speed blender for a smooth batter, and a texture that’s closer to cake. I used my Vitamix, and blended for just 30 seconds.
Feel free to omit the egg if you don’t want to use it, but keep in mind that your oats won’t be as fluffy as they should be.
You can make different flavors such as carrot cake by adding grated carrot, or make a chocolate version by adding cocoa powder.
Nutrition: This is a rough estimate per portion without peanut butter.
