Tips for the Best Baked Oatmeal

Use Rolled Oats

Old-fashioned rolled oats provide the best texture for baked oatmeal. Quick oats can become too soft, while steel-cut oats require a different cooking method.

Warm the Peanut Butter

If your peanut butter is thick, warming it slightly before mixing will help it blend smoothly with the wet ingredients.

Don’t Overbake

The oatmeal should be set but still slightly soft in the center. Overbaking can make it dry.

Let It Rest

Allowing the bake to cool for about 10 minutes helps it firm up and makes slicing easier.

Banana Peanut Butter

Almond Butter and Jam

Sprinkle granola or chopped nuts over the top before baking for extra texture.
