These "baked" cocoa-banana oats are the perfect quick breakfast on a busy morning. With honey as a natural sweetener and milk and peanut butter as thickeners, this delicious treat reaches the perfect creamy consistency after just a few minutes in the microwave. The best part is that since it's in a mug, on busy days you can walk right out the door with it.

If you're new to the oats game, it's important to know the difference between steel cut oats and rolled oats so you get the right ones. They're not interchangeable without a serious texture change. Steel cut oats are less processed, making them coarser and chewier than rolled oats. They also have a distinct nutty flavor. Rolled oats, on the other hand, go through a steaming and flattening process. This gives them a milder flavor and much softer texture, making them the perfect base for this quick breakfast idea.

We've built this oatmeal recipe to be user-friendly by giving you some fun alternatives to choose from. Instead of milk, give oat or nut milk a try. They're just as creamy and add a hint of sweetness. Instead of creamy peanut butter, try cashew butter. To top it off (literally), you can sprinkle some extra slices of banana, some fresh raspberries, or some chopped nuts on top for a fancy garnish to make your morning meal a memorable one.
