Ingredients

Here’s everything you’ll need to make these easy peanut butter oat cups:

1 ½ cups rolled oats
¾ cup natural peanut butter (creamy)
⅓ cup honey or maple syrup
2 tablespoons coconut oil, melted
1 teaspoon vanilla extract
Pinch of salt
¾ cup dark or semi-sweet chocolate chips
1 teaspoon coconut oil (for melting chocolate)

Ingredient Notes & Substitutions

Rolled Oats:
Old-fashioned rolled oats give the best chewy texture. Quick oats can work but will create a softer base.

Peanut Butter:
Natural peanut butter with just peanuts and salt works beautifully. If it’s very runny, refrigerate it briefly before mixing.

Honey or Maple Syrup:
Honey creates a firmer texture, while maple syrup keeps it fully vegan.

Coconut Oil:
Helps bind the base and creates a smooth chocolate topping. You can substitute butter if not dairy-free.

Chocolate Chips:
Dark chocolate adds richness, but milk chocolate works if you prefer a sweeter finish.

Instructions

Prepare the Pan
Line a muffin tin with paper liners or use a silicone muffin mold for easy removal.
Mix the Base
In a medium mixing bowl, combine peanut butter, honey (or maple syrup), melted coconut oil, vanilla extract, and salt. Stir until smooth.
Add the Oats
Fold in the rolled oats until fully coated and evenly mixed.
Form the Cups
Scoop about 2 tablespoons of the oat mixture into each muffin cup. Press down firmly with the back of a spoon to create a compact, even layer.
Melt the Chocolate
In a microwave-safe bowl, combine chocolate chips and 1 teaspoon coconut oil. Microwave in 20-second intervals, stirring between each, until smooth.
Top with Chocolate
Spoon melted chocolate over each oat cup, spreading evenly to cover the surface.
Chill to Set
Place the tray in the freezer for 20–30 minutes, or until the chocolate is firm and the cups are set.
Serve or Store
Remove from liners and enjoy! Store in an airtight container in the freezer for up to 3 months.

Tips for Perfect Peanut Butter Oat Cups

Press Firmly
Compact the oat mixture well so the cups hold together once chilled.

Use Silicone Molds
They make removal effortless and keep the edges clean.

Add Texture
Stir chopped nuts, chia seeds, or shredded coconut into the oat base for extra crunch.

Balance Sweetness
Taste the base before forming the cups. Add a drizzle more honey if you prefer sweeter treats.

Fun Variations to Try

Chocolate Swirl

Swirl a little peanut butter into the melted chocolate before topping.

Protein Boost

Add 2 tablespoons of vanilla or chocolate protein powder to the oat mixture.

Nut-Free Version

Swap peanut butter for sunflower seed butter.

Coconut Lovers

Add 2 tablespoons shredded coconut to the base.

Crunchy Delight

Mix in crushed pretzels or rice cereal for a crispy texture.
