How to Make Monster Cookie Oat Cups
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!

Monster Cookie Oat Cups
Ingredients
Oat Layer
- 2 cups quick-cooking oats
- ½ cup honey
- ⅓ cup all-natural creamy peanut butter
- ⅓ cup mini chocolate chips
- Optional: 1-2 teaspoons water
Chocolate Layer
- 6 oz. dark chocolate, chopped
- 2 teaspoons coconut oil
Peanut Butter Layer
- ½ cup all-natural creamy peanut butter
- 1 teaspoon coconut oil
- ¼ cup mini M&M’s
- 2 tablespoons mini chocolate chips
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.
- 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.
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.

These were yummy. Would definitely make again.
Hey! Do these have to be stored in the freezer or can they be kept in the fridge?
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!
Soooo delicious!!! My kids and I love them so much!!
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?
Too bad there a huge photos when printing out the recipe.
Hi Jennifer, Feel free to use the “print recipe” button in the recipe card where you can choose to uncheck the “include instructional images” box. Hope this helps!
Oil alternatives other than coconut oil? Still the same amount say I’m using avocado oil?
Hi Kassidy — if you’re not using coconut oil, we recommend omitting! The chocolate layer will be a little harder (similar to bar chocolate).
I use the same amount of butter. And it work just fine.
Can you use regular peanut butter instead of natural?
These were so easy and so delicious!!
So happy to hear it, Shell!
