Ingredients
- 2 cups rolled oats
- 1 cup creamy peanut butter
- 1/2 cup honey or maple syrup
- 1 teaspoon vanilla extract
That’s it. Four ingredients. Pure magic.
Ingredient Breakdown and Substitution Tips
Rolled Oats
Old-fashioned rolled oats work best for structure and texture. They provide chewiness and help the cups hold together once chilled.
Substitution tip: Quick oats can be used for a softer texture, but avoid steel-cut oats, as they are too hard and won’t soften properly in this no-bake recipe.
Peanut Butter
Creamy peanut butter creates that rich, smooth base. Natural peanut butter works too, but make sure it’s well stirred before using.
Substitution ideas:
- Almond butter
- Cashew butter
- Sunflower seed butter (for nut-free option)
Honey or Maple Syrup
This acts as the natural sweetener and binder. Honey creates a slightly firmer texture, while maple syrup offers a deeper flavor.
Vanilla Extract
It may seem small, but vanilla enhances the overall flavor and adds warmth.
Instructions
- Line a 12-cup muffin tin with paper liners or lightly grease each cavity.
- In a microwave-safe bowl, gently warm the peanut butter and honey (or maple syrup) for about 20–30 seconds until smooth and easy to stir.
- Stir in the vanilla extract until fully combined.
- Add the rolled oats to the peanut butter mixture and stir thoroughly until all oats are coated evenly.
- Scoop the mixture into each muffin cup, pressing firmly with the back of a spoon to compact the mixture.
- Place the muffin tin in the refrigerator for at least 60 minutes, or until the cups are firm.
- Remove from the tin and store in an airtight container in the refrigerator or freezer.
That’s it — your no-bake peanut butter oat cups are ready to enjoy.
