Notes
Texture & Flavor Breakdown
These oat cups are designed to be:
- Soft but sturdy, holding together without crumbling
- Creamy from the peanut butter, balanced by hearty oats
- Lightly sweet, not overpowering
- Comforting and filling, thanks to fiber and healthy fats
Chilling allows the peanut butter to set, giving the cups structure while keeping the texture tender.
The Beauty of a 4-Ingredient Recipe
When recipes are this simple, every ingredient matters. Rolled oats provide structure and chew, peanut butter acts as both binder and flavor base, honey adds natural sweetness, and salt sharpens everything just enough to keep the flavors balanced.
No fillers, no unnecessary extras — just straightforward ingredients doing exactly what they’re supposed to do.

Once you’ve mastered the base recipe, there are endless ways to adapt it:
- Chocolate Chip Version: Stir in mini chocolate chips
- Chocolate Peanut Butter Cups: Add a thin chocolate layer on top
- Nut-Free Option: Use sunflower seed butter instead of peanut butter
