Everything You Need to Know About Baking Muffin Cups

Baked oatmeal cups are essentially a hearty oat muffin, so you’ll see that the recipe below is mixed via the muffin method: Wet ingredient and dry ingredients are mixed together in separate bowls before they’re combined. However, baked oatmeal cups do not include flour, so the mixture is held together with a combination of egg, dairy, and applesauce. Nut butter is added to the wet mixture for flavor and texture. Portion the batter into a muffin pan and top the cups with your favorite oatmeal toppings before baking.

Here are some pointers for making tender and tasty oatmeal cups that never bake up dry.

Use cooking spray, not muffin liners.

Coat a standard 12-well muffin tin with cooking spray instead of using muffin liners. The baked oatmeal cups benefit from direct contact with the baking pan, resulting in a thin, crisp outer layer. Plus, this means you won’t have to fight the finished cups out of the paper liner.

Make them gluten-free (if you want).

These baked oatmeal cups do not require any flour, so use gluten-free oats to make these truly gluten-free. You can also omit the nut butter if you have a nut allergy at home.

Use your favorite combination of sweeteners.

Baked oatmeal cups get their sweetness from a combination of applesauce and maple syrup, but you can easily swap the applesauce for another fruit purée — try mashed bananas, canned pumpkin purée, or even one of your kid’s vegetable squeeze pouches. The same goes for sweeteners — maple syrup can be replaced with honey, or you can use a few tablespoons of brown sugar instead.

Top the oatmeal cups with add-ins.

Instead of folding the nuts or dried fruit into the baked oatmeal, sprinkle them on top. This makes it easy to make a batch with several different flavors and customize cups for picky eaters.

Store in the fridge.

These portable oatmeal cups bake up moist and tender, thanks to the milk and fruit. Store them in the refrigerator so they’ll last longer; reheat in the microwave or toaster oven to rewarm.

Have Them Your Way

Its hard to overstate how adaptable this recipe is. Keep the number of eggs, the amount of liquid, and the measure of oats the same, and you can tinker with the other ingredients, making these an ideal vehicle for using up small amounts of pantry ingredients.

Here are some of my favorite combinations.

  • Use pumpkin purée and top with chopped dried apples and pumpkin seeds.
  • Use mashed banana and top with dried blueberries and chopped walnuts.
  • Top the oatmeal cup with mini chocolate chips and plump dried cherries.
  • Swap the almond butter for cashew butter and top with chopped cashews and dried mango.

How to Store and Serve Baked Oatmeal Cups

These baked muffin cups store best in the refrigerator in an airtight container for about five days. They can also be individually wrapped and stored in the freezer for at least a month. Reheat the cups in the microwave or toaster over to enjoy on a cold morning, or eat them cold. You can break them up to serve over yogurt or even in milk. Cut them in half and slather with more nut butter, cream cheese, or jelly for a really luxurious baked oatmeal experience.
