You’ve got oats, peanut butter, and, most likely, some overripe bananas on the counter. You probably have some chocolate–chips, chunks, or other bits that can be chopped–too.

In other words, you have the makings of your new favorite portable breakfast.

Specifically, Peanut Butter Banana Baked Oatmeal Cups. You need to make a batch asap.

You can make a batch of these oatmeal cups days before, the night before, or shortly before you want to eat them. They take little time and effort and can be stored, in the refrigerator or freezer, for a grabbable breakfast to go.

Ingredients

The exact amounts of each ingredient are indicated in the recipe card at the end of the post. Toggle between US Customary (volume) and Metric (weights) for preferred measurement option.

  • mashed very ripe bananas (from very soft and mushy bananas, with lots of black spots on the peels)
  • peanut butter (or other nut butter or seed butter; see notes for options)
  • flaxseed meal
  • coconut sugar (see notes for options)
  • vanilla extract
  • rolled oats (old-fashioned rolled oats or quick-cooking oats; certified GF, as needed)
  • baking powder (certified GF, as needed)
  • fine sea salt
  • semisweet chocolate chips (I like to use mini chips for greater distribution throughout)

The 1/4 teaspoon salt is optional. You can make the muffin cups without it. Also, you may want to use less salt if the peanut butter is well-salted.

Step by Step Instructions

Note that the complete directions are also in the recipe card below.

Step One: Preheat Oven and Prepare Muffin Tin

Preheat oven to 350F (180C). Line all twelve cups of a standard size muffin tin with silicone muffin liners, paper liners or foil liners. If you eat some oil, you can also omit the liners and spray the cups with nonstick cooking spray.

Step Two: Whisk the Wet Ingredients

In a large mixing bowl, whisk the peanut butter, mashed banana, flaxseed meal, coconut sugar, water (or nondairy milk) and vanilla until blended. Note that you do not need to make a separate flax egg, the flax is gelled when added to the wet ingredients.

Step Three: Add the Dry Ingredients

Add the rolled oats, baking powder, salt, and 4 tablespoons of the chocolate chips. 

Mix until all of the ingredients are completely blended.

Step Four: Portion Batter

Scoop the oat batter into the prepared muffin cups. Dot the tops of each cup with the remaining chocolate chips.

Step Five: Bake

Bake the oatmeal cups in the preheated oven for 23 to 26 minutes until golden brown, slightly puffed and the centers are set.

Step Six: Cool

Leave the oatmeal cups in the muffin tin for 15 minutes before removing. They will become more firm as they sit. Remove from the muffin pan and serve, or cool completely.

I love these oatmeal cups best when they are slightly warm: not too hot to munch my way through, but warm enough to keep the chocolate melt-y.

Optional: Add a Peanut Butter Drizzle

If you love peanut butter (that would include me), I strongly suggest an extra drizzle of peanut butter on top before gnoshing.

Store the cooled oatmeal cups in an airtight container in the refrigerator for 5 days or the freezer for up to 6 months.

FAQ

  • What kind of oats should I use in the recipe? Either quick oats or old fashioned oats can be used. Do not use oats labeled “instant.”Steel cut oats will not work either. They are too thick.
  • What can I use in place of peanut butter? An equal amount of any other smooth nut butter or seed butter can be used in place of the peanut butter. For example, almond butter, cashew butter, sunflower seed butter, pumpkin seed butter or tahini.
  • What can I use in place of coconut sugar? You can substitute an equal amount of the granulated sweetener of your choice (e.g., brown sugar, granulated cane sugar) or liquid sweetener (e.g., pure maple syrup, agave nectar, date syrup, brown rice syrup or (if not following a vegan diet) honey)) for the coconut sugar.
  • What can I use in place of chocolate chips? Leave them out entirely, or swap them for chopped dried fruit (e.g., raisins, dried cranberries, dried apricots, or prunes) and/or chopped nuts or seeds, such as walnuts, peanuts, almonds, pumpkin seeds or sunflower seeds. You can also top each oatmeal cup with banana slices.
  • What can I use in place of bananas? An equal amount of unsweetened applesauce can be used in place of the bananas. Keep in mind that applesauce is much less sweet than very ripe banana, so you may want to add additional sweetener.

Happy baking!

  1. great recipe! I made them without any extra sugar (only bananas and chocolate chips) and they were still very sweet, so good for a healthy breakfast that satisfies. thanks for this!

  2. These oatmeal cups are wonderful–we made them last weekend and scarfed them up all week. Thanks for a keeper of a recipe.

  3. The combination of banana and peanut butter, plus warm chocolate chips, is heavenly! This is a winner, it is going on my permanent recipe rotation.

  4. I just made these and could not wait the 15 minute for them to cool, so I ate one while it was still hot. Got a little burned from the melted chocolate and it was worth it! LOVE!!!

  5. Perfect recipe. I’ve also made them with almond butter, with applesauce and dried cranberries in place of the banana and chocolate chips.
