Baked oatmeal cups are oatmeal you can eat with one hand. This apple cinnamon version swaps the usual butter and oil for Greek yogurt, which keeps the cups moist and brings the protein up to about 18 grams per serving.
They taste like apple crisp, they freeze beautifully, and one pan of 12 covers six breakfasts.

Why You’ll Love This Recipe
- About 18g protein and 6g fiber per serving of 2 cups
- Tastes like apple crisp with no refined flour or butter
- Freezes for 3 months for easy mornings
- About 10g of fat per serving
Ingredient Notes
Use old-fashioned rolled oats for the best chew; quick oats work but make the cups softer. Plain nonfat Greek yogurt is what keeps these moist, so do not swap in regular yogurt. Dice the apple small, about 1/4 inch, so every cup gets some in each bite.
How It Comes Together
- Mix the wet ingredients, then the dry
- Fold in apples and walnuts
- Bake 25 minutes in a greased 12-cup tin
