FAQs
Can I use other nut butters instead of peanut butter?
Yes, almond or cashew butter can be good substitutes, though the flavor and texture may vary slightly.
Do I need to use protein powder in the filling?
No, the protein powder is optional and can be added if you want to boost the protein content. The regular filling with just peanut butter works perfectly well.

Ingredients
Oat Base
- 2/3 cup peanut butter
- 3/4 cup old fashioned rolled oats
- 2 tbsp maple syrup
Regular Filling
- 1 tbsp peanut butter per oat cup
Protein Filling (Optional)
- 1/2 cup peanut butter

Chocolate Coating
- 1 cup chocolate chips
- 2 tsp oil (for melting)
- Flaky sea salt (optional)
Instructions
- Prepare the oat base: In a mixing bowl, stir together the peanut butter and maple syrup until smooth and well combined. This creates the sticky binder for the oat base.
- Add oats: Add the rolled oats to the peanut butter mixture and mix until fully combined, ensuring the mixture is sticky and uniform.
- Form the base: Scoop about 2 tablespoons of the oat mixture into silicone muffin molds. Press down firmly with a spoon to form an even, compact base to prevent crumbling later.
- Add filling: Top each oat base with 1 tablespoon of peanut butter for the regular filling, or mix peanut butter with protein powder to create the protein filling. Spread the filling evenly over each base.
- Freeze to set base and filling: Place the molds in the freezer for 20 minutes to firm up the oat base and filling layers.
- Melt the chocolate: In the microwave, melt the chocolate chips with oil in 30-second increments, stirring well between each until smooth and glossy.
- Coat with chocolate: Spoon the melted chocolate over each cup, fully covering the filling layer.
- Final freeze: Return the cups to the freezer for another 20 minutes or until the chocolate topping is completely set and firm.
- Serve: Remove the cups from the silicone molds, sprinkle with flaky sea salt if desired, and enjoy right away or store them in the freezer.
