Ingredients
Makes 12 oat cups
For the Oat Base

- 1/2 cup (125g) creamy peanut butter
- 1/3 cup (110g) honey (or maple syrup)
- 1/4 cup (30g) ground flaxseed (optional, for extra nutrition)
- 1 teaspoon vanilla extract
- Pinch of salt
For the Chocolate Topping
- 1/2 cup (90g) chocolate chips (semi-sweet or dark)
- 1 tablespoon coconut oil (or butter)
Preparation Time
- Prep time: 15 minutes
- Chill time: 1–2 hours
- Total time: About 1 hour, 15 minutes (or longer for firmer cups)
Step-by-Step Instructions
Step 1: Make the Peanut Butter Mixture
In a microwave-safe bowl (or saucepan), warm peanut butter and honey for 20–30 seconds until soft and easy to stir. Mix until smooth.
Step 2: Combine with Oats
Add rolled oats, ground flaxseed (if using), vanilla, and salt. Stir until everything is evenly coated and the mixture looks thick and sticky.
Step 3: Press into Cups
Line a muffin tin with paper liners (or lightly grease). Spoon the mixture evenly into 12 cups and press down firmly with the back of a spoon to pack them tightly.
Step 4: Melt the Chocolate
Melt chocolate chips and coconut oil together in the microwave in 20-second bursts, stirring each time until smooth.
Step 5: Top and Chill
Spoon melted chocolate over each cup and spread lightly. Refrigerate for 1–2 hours until set.
Step 6: Serve
Peel off liners and enjoy. Store leftovers chilled for best texture.

- Add chopped peanuts or mini chocolate chips for extra crunch.
