Variations

Swap the nut butter: can’t do peanuts? Use almond butter or cashew butter instead and make sure to swap the peanuts, too.

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

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

Ingredients 

Oat Layer

  • 2 cups quick-cooking oats
  • ½ cup honey
  • cup all-natural, creamy peanut butter
  • cup chopped peanuts
  • Optional: 1-2 teaspoons water

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 silicon muffin pan (no need to line the silicone pan).
  • First, make the oat layer. Add the quick-cooking oats, honey, peanut butter, and peanuts 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 chocolate chips to the top of each cup.

Tips & Notes

We used chopped chocolate pieces, but feel free to use chocolate chips. Use a kitchen scale to weigh the chocolate chips.
If you don’t like dark chocolate you can use milk chocolate instead.
We do not recommend using rolled oats. Old-fs rolled oats are would be too tough in these oats.
Be sure you let the oat cups set and firm up long enough before storing them in the freezer.

Samoa Oat Cups

These Samoa Oat Cups taste like your favorite girl scout cookie and are made with 3 epic layers of oats, chocolate, and coconut. Check out the Reel HERE.

Yields: 12

Ingredients

Oat Layer 

  • 1.5 cups quick-cooking oats
  • 1/2 tablespoons maple syrup
  • 1/3 cup cookie butter, melted
  • 1-2 tablespoons water, as needed

Chocolate Layer 

  • 3/4 cup semi-sweet chocolate chips 
  • 2 teaspoons coconut oil 

Coconut Layer 

  • 1/3 cup creamy cashew butter, drippy 
  • ⅓ cup cookie butter melted
  • 1 cup unsweetened shredded coconut 

Top  Layer

  • Drizzle chocolate 

Method

  1. Line a metal muffin pan with paper liners or use a silicon muffin pan (no need to line the silicone pan).
  2. First, 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.
  3. Scoop 1 teaspoon of the melted chocolate to the bottom of each muffin cup and use the end of a spoon or your finger to spread the chocolate across the bottom.
  4. Next, make the oat layer. Add the quick-cooking oats, maple syrup, and cookie butter to a bowl and stir the ingredients together until combined. If it seems dry, add 1 to 2 teaspoons of water. Scoop about 2 tablespoons of the oats over the chocolate layer and firmly press the oats into the chocolate. Place the muffin pan in the freezer for 5 minutes. 
  5. Make the coconut layer. Add the cashew butter, cookie butter, and coconut to a bowl and mix to combine. Scoop 1 tablespoon of the coconut mixture onto the oat layer and evenly spread the coconut layer. 
  6. Transfer the remaining melted chocolate to a piping bag or plastic bag. Snip the tip of the bag and carefully drizzle the melted chocolate over the coconut layer in a zigzag design similar to a caramel delight.  
  7. Place the muffin tin in the freezer for at least 30 minutes to an hour to set.
  8. When the oat cups have been set remove them from the muffin pan and transfer them into a freezer bag and store the oat cups in the freezer.

Recipe Notes

  • If you don’t like semi-sweet chocolate you can use milk chocolate instead.
  • We do not recommend using rolled oats. Old-fashioned rolled oats would be too tough in these oat cups.

Yields: 12

Oat Layer 

  • 2/3 cup chopped, dehydrated strawberries
  • 1 cup quick-cooking oats
  • 2 tablespoons honey

  1. Line a mini muffin pan with paper liners or use a silicon muffin pan (no need to line the silicone pan).
  2. Transfer the dehydrated strawberries to a clean coffee grinder or a food processor. Process the strawberries on high until a fine powder is created. 
  3. Add 4 tablespoons of the strawberry powder (set the rest of the strawberry powder aside), quick-cooking oats, honey, and cashew butter to a bowl, and stir all of the ingredients together until combined. The mixture should be sticky and easily stick together. If it seems dry, add 1 to 2 teaspoons of water. 
  4. Scoop 1 heaping teaspoon of the oats into the bottom of each muffin cup and firmly press them into the cup.
  5. 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.
  6. Scoop 1 heaping teaspoon 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.
  7. Finally, make the cashew layer. Add the cashew butter and coconut oil into a separate microwave-safe bowl and microwave the mixture for 15 seconds. Stir until well combined. Add 1 heaping teaspoon of the cashew butter mixture to the top of the chocolate layer. Swirl the pan again to even out the cashew butter. Then, sprinkle the strawberry powder over the top of the cashew butter. 
  8. Place the muffin tin in the freezer for at least 30 minutes to an hour to set.
  9. 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.

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

Coconut Mango Oat Cups

These oat cups are a fusion of coconut mana and freeze-dried mango all packed into 3 layers! Check out the reel HERE.

Yields: 12

Ingredients

Oat Layer

  • 1 cup quick-cooking oats
  • 2 unsalted rice cakes, separated (~1 cup)
  • ⅓  cup agave syrup
  • ⅓ cup creamy and drippy cashew butter* 
  • 2 tablespoons black sesame seeds* 

Cashew Butter Layer 

  • ½ cup cashew butter 
  • 1 teaspoon coconut oil 

Coconut Layer

  • ½ cup melted coconut mana
  • 2 teaspoons coconut oil  

Toasted Coconut Layer 

  • ½ cup toasted coconut
  • ¼ cup freezer-dried mango crumbles 

Method

  1. Line a muffin tin with paper liners or use a silicone muffin pan. 
  2. Prepare the oat layer. Mix the oats, rice cakes, agave syrup, cashew butter, and sesame seeds in a bowl. Use a spoon or hands to massage all of the ingredients together. 
  3. Scoop a heaping tablespoon and a half into each muffin cup. Press the mixture firmly into the bottom of the muffin cup. Transfer the muffin pan to the freezer while preparing the other layers. 
  4. Prepare the cashew butter layer. Add the cashew butter and coconut oil to a bowl and microwave on high for 30 seconds. Stir until drippy and creamy. 
  5. Remove the muffin pan from the freezer and add about 2 teaspoons of the cashew butter mixture to the top of the oat layer. Swirl the cashew butter layer so it is evenly spread. Freeze for at least 15 minutes. 
  6. Prepare the coconut layer. If your coconut mana comes in a glass jar, place the jar in a saucepan and add water to the saucepan about halfway up the glass jar. Heat over medium heat. The coconut mana will begin to melt slowly. Be sure to stir the coconut mana throughout melting. Do not microwave the mana and allow the mana to melt slowly or it will seize. 
  7. When the coconut mana has melted and is smooth and creamy, measure out ½ cup and add melted coconut oil to the mana. Be sure the coconut oil is warm or the coconut mana will seize. 
  8. Remove the muffin tin from the freezer and add 1.5 heaping teaspoons to each muffin cup. Use the teaspoon to evenly spread the coconut layer. 
  9. Quickly top each cup with toasted coconut and mango crumbles. Press the toppings into the coconut layer. 
  10. Freeze the muffin cups for at least 1 hour before removing the cups from the muffin pan.  
  11. When the oat cups are set, remove them from the muffin pan, transfer them into a freezer bag, and store the oat cups in the freezer.

Recipe Notes

  • Make sure to use drippy cashew butter where the oil separates from the nut butter. Mix and then use. 
  • White sesame seeds can be used in place of black sesame seeds. 
  • Coconut mana can be a bit sensitive. Just be sure to slowly warm the mana and always add warm to warm. If you add cold things to warm coconut mana it will seize. Feel free to add more coconut oil than is called for if you want the coconut layer to be runnier. 
  • You can find freezer-dried mangos at Trader Joe’s, Target, or Amazon.

These should win some type of award! They are delicious! They are filling and satisfy a sweet tooth. We make at least 3 batches/week (family of 5). I love them for dessert. My teen loves one for breakfast on her way out the door and it keeps her full until lunch. I have even reduced the amount of chocolate to 3-4 oz and peanut butter topping to 1/3 of a cup and there are no complaints.

These are quick and easy to make, and quick to disappear!! The whole family loved them. I omitted the chopped peanuts – I love peanut butter but not whole peanuts (weird?). Sprinkled half with flaky sea salt and these ones were sooooo good! Next time I make them they all get the salt!

This is such an easy delish recipe! I am 4 weeks postpartum and managed to make them with the baby strapped to me and it’s nice to have an easy grab and go snack to fuel me while breastfeeding! I only had quick steel cut oats which are a little tough but still yummy. Will make again!
