Peanut Butter Granola Bars


These peanut butter granola bars are so EASY! The best peanut butter granola bars recipe without honey, that tastes like honey roasted peanuts.




  1. Line an 8-inch square baking pan with parchment paper or wax paper. Set aside. You can also use a granola bar pan set on a small cookie sheet for stability. Clear some space in the freezer for this pan—you will need it later.
  2. In a medium, microwave-safe bowl (large enough to add oats later), add peanut butter and maple syrup. Whisk together until well mixed. Heat in 20-second increments in the microwave until warm, fragrant, and bubbles begin to form.* Whisk in between heating increments. **Stovetop instructions in Notes.
  3. Add oats to the peanut butter mixture. Using a rubber spatula, stir and fold until thoroughly combined. Pour this mixture into the prepared baking pan. Using the rubber spatula, smooth into an even, tightly packed layer. If using a granola bar pan, evenly distribute mixture into the crevices in the pan. Using a small spoon, press down into a very tightly-packed layer.
  4. Freeze for 25-35 minutes, or until firm and completely chilled. Slice into 18 bars (3 columns by 6 rows), or release bars from granola bar pan. Enjoy! Storing instructions below.

Where to Buy Ingredients: Gluten Free Rolled Oats | Unsalted Natural, Creamy Peanut Butter | Pure Maple Syrup

*How long do I heat up the peanut butter & maple syrup? Heat this mixture until a small amount of tiny bubbles form. You just want to cook the syrup and peanut butter together—not to worry, this isn’t a super finnicky thing. You just want to warm the two ingredients cohesively together. Mine took 4 rounds of 30 seconds each.

**Stovetop Instructions: In a medium saucepan over medium-low heat, add peanut butter and maple syrup. Whisk until well incorporated. Stir occasionally, heating until this mixture begins to bubble. Remove from heat and carefully pour over oats (in a heatproof mixing bowl).

Refrigerator Storing Instructions: Store in an airtight container in the refrigerator for 1-2 weeks.

Room Temperature Storage: After the first day, you can store them at room temperature—they’ll be more firm.

How to make Vegan: keep the recipe as is! 🙂

How to make Gluten Free: use gluten free rolled oats.
