Ingredients You’ll Need
Here’s what makes these no-bake peanut butter oat cups so simple:
Oat Flour
You can easily make your own oat flour by blending rolled oats in a food processor until very fine. Rolled oats are typically steamed before processing, making them generally safe to eat raw. If you’re sensitive or immunocompromised, consider heat-treating the oats first.
Peanut Butter
Any peanut butter works—natural peanut butter or classic brands like Skippy. You can also substitute almond butter, cashew butter, or sunflower seed butter.
Maple Syrup
Pure maple syrup adds natural sweetness and a rich flavor. Honey can also be used if preferred.
Chocolate Chips
Semi-sweet chocolate chips are classic, but dark chocolate, milk chocolate, or white chocolate all work beautifully.
Optional: Coconut Oil
A small amount helps the chocolate melt smoothly and set with a glossy finish.
Step-by-Step Instructions
1. Warm the Peanut Butter Base
Add the peanut butter and maple syrup to a microwave-safe bowl. Microwave for 40–60 seconds, then stir until smooth and fully combined.
2. Mix in the Oat Flour
Gradually add the oat flour and mix well. The mixture will be thick and dense but should still be easy to press into molds. If it feels too dry, add a teaspoon of peanut butter or maple syrup at a time.
3. Form the Cups
Line a muffin pan with paper liners or use a silicone muffin pan. Press the peanut butter oat mixture evenly into each cup.
4. Melt the Chocolate
In a small microwave-safe bowl, melt the chocolate chips with the coconut oil (if using) in 30-second increments, stirring between each round until smooth.
5. Add the Chocolate Layer
Pour melted chocolate over each cup and smooth the tops with the back of a spoon. Optional: sprinkle flaky sea salt, sprinkles, or mini chocolate chips on top.
6. Chill Until Set
Refrigerate for 2–3 hours until fully firm. Remove carefully and store chilled.
Recipe FAQs
Can I use a different nut butter?
Yes! Almond butter, cashew butter, sunflower seed butter, or mixed nut butter all work well.
Can I use another type of flour?
Because this is a no-bake recipe, only use flours that are safe to eat raw, such as oat flour or almond flour. Regular wheat flour must be heat-treated first.
How should I store them?
Store in an airtight container in the refrigerator for up to 5 days for best freshness.
Tips for Success
- Use silicone muffin pans or liners for easy removal
- Keep these cups refrigerated, as they soften at room temperature
- For variety, try adding pumpkin puree and pumpkin spice for a seasonal twist
