Peanut Butter

Smuckers All-Nautral Peanut Butter is our go-to drippy peanut butter for baking!

Ingredients for monster cookie oat cups in a bowl.

make the oat layer

Add the quick-cooking oats, honey, peanut butter, and mini chocolate chips to a bowl and stir all of the ingredients together until combined.

If it seems dry, add 1 to 2 teaspoons of water.

Scoop about 2 tablespoons of the oats into the bottom of each muffin cup and firmly press them into the cup. 

Mix the chocolate layer

Transfer the chocolate and coconut oil into a microwave-safe bowl. Heat the chocolate on high for 20-second increments until the chocolate is melted, stirring in between each increment. 

Scoop 2 teaspoons of the melted chocolate and add it on top of the oat layer. Swirl the muffin pan in a circle to easily distribute the chocolate over the oats.

Place the muffin pan in the freezer for 5 minutes. 

Make the peanut butter layer

Add the creamy peanut butter and coconut oil into a separate microwave-safe bowl and microwave the mixture for 15 seconds, and stir to combine.

Add 2 teaspoons of the peanut butter mixture to the top of the chocolate layer. Swirl the pan again to even out the peanut butter.

Then, add mini m&ms and mini chocolate chips to the top of each cup. 

Let set in the freezer

Place the muffin tin in the freezer for at least 30 minutes to an hour to set. 

When the oat cups have set, remove them from the muffin pan and transfer them into a freezer bag and store the oat cups in the freezer. Enjoy now or later!

Variations

Swap the nut butter: can’t do peanuts? Use almond butter or cashew butter instead.

Add an extract: A little bit of vanilla or almond extract in the base of these would be delicious.

Use another mini chip: we love mini chocolate chips in these oat cups, but mini peanut butter chips, butterscotch chips or white chocolate chips would taste great too.

Use a dried or freeze-dried fruit: Instead of mini M&M’s, use a dried or freeze-dried fruit such as strawberries, raisins, or blueberries.

Can I use a full-size muffin tin instead?

Feel free to use a regular-sized muffin tin instead of a mini one. You’ll make less total oat cups, but each one will obviously be a larger size. Yum!

Is this recipe gluten free?

All ingredients in this recipe are naturally gluten-free. Just make sure you read the labels of the ingredients you buy to confirm they were produced in a certified GF facility.

Is this dessert healthy?

Since these monster cookie oat cups are made with whole grains and all-natural sugars, it’s a nutritious dessert idea.

Ingredients 

Oat Layer

Chocolate Layer

  • 6 oz. dark chocolate, chopped
  • 2 teaspoons coconut oil

Peanut Butter Layer

Instructions 

  • Line a metal muffin pan with paper liners or use a silicone muffin pan (no need to line the silicone pan).
  • First, make the oat layer. Add the quick-cooking oats, honey, peanut butter, and mini chocolate chips to a bowl and stir all of the ingredients together until combined. If it seems dry, add 1 to 2 teaspoons of water. Scoop about 2 tablespoons of the oats into the bottom of each muffin cup and firmly press them into the cup.

  • Next, mix the chocolate layer. Transfer the chocolate and coconut oil into a microwave-safe bowl. Heat the chocolate on high for 20-second increments until the chocolate is melted. Be sure to stir the chocolate and coconut oil in between each increment.

  • Scoop 2 teaspoons of the melted chocolate and add it on top of the oat layer. Swirl the muffin pan in a circle to easily distribute the chocolate over the oats. If there is any melted chocolate left in the bowl evenly distribute the chocolate into each cup. Place the muffin pan in the freezer for 5 minutes.
  • Finally, make the peanut butter layer. Add the creamy peanut butter and coconut oil into a separate microwave-safe bowl and microwave the mixture for 15 seconds. Stir until well combined. Add 2 teaspoons of the peanut butter mixture to the top of the chocolate layer. Swirl the pan again to even out the peanut butter. Then, add mini m&ms and mini chocolate chips to the top of each cup.

Tips & Notes

  • We do not recommend using rolled oats. Old-fashioned rolled oats would be too tough in these cups.
  • Be sure you let the oat cups set and firm up long enough before storing them in the freezer.

Thank you for including the nutritional facts. Can you tell me how many you are getting out of this recipe? Thanks!
Also, I’ve tried some white chips and oreo crumbs to shake it up a bit but I’ve gotta say the original toppings are best!

These turned out pretty well. Made them last night and popped them in the freezer. Tried one this morning and were great!

For the nutritional facts, were these based on a serving of 1 piece?

Is it possible to use liquid coconut oil? Or can you only use solid-ish coconut oil?
