The Power of Peanut Butter and Oats

Peanut butter provides richness, healthy fats, and protein, while oats add structure and a chewy texture. Together, they create bars that are filling without feeling heavy.

Using rolled oats keeps the texture hearty, while honey or maple syrup binds everything together naturally.

Ingredients That Work Together

Each ingredient plays a role in flavor and texture:

Rolled Oats: Provide chew and structure
Peanut Butter: Adds creaminess and richness
Honey or Maple Syrup: Natural sweetness and binding
Vanilla Extract: Enhances flavor
Chocolate Chips: Optional but highly recommended
Coconut Oil: Helps chocolate set smoothly

Rolled oats
Natural peanut butter
Honey or maple syrup
Vanilla extract

Instructions

Line an 8×8-inch pan with parchment paper.
In a bowl, mix oats and peanut butter until combined.
Add honey (or maple syrup) and vanilla extract.
