How to Make Peanut Butter Granola Bars

Learn how to make peanut butter granola bars the easy way, then let me know what you think! 🙂

Line a baking pan

Line a square baking pan with parchment paper or wax paper. Set it aside for later. 

 

Make the peanut butter mixture

Add peanut butter and maple syrup to a mixing bowl. Then, whisk the two ingredients together until thickened. This is your sweetened peanut butter mixture!

Heat until warm

Heat the bowl of sweetened peanut butter until warm and just a few bubbles form.

Look for just a small amount of tiny bubbles 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 because it will be the glue for your granola bars. Mine took 4 rounds of 30 seconds each.

Add oats

Add oats to the warm, sweetened peanut butter mixture. Use a rubber spatula to fold it all together to create the dough for your peanut butter granola bars.

Description

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


Ingredients

Scale
  • 1 cup natural, unsalted creamy homemade peanut butter or store-bought
  • ½ cup pure maple syrup
  • 2 ½ cups rolled oats

Instructions

  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.

Notes

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.

Nutrition Information: is an estimate based on the ingredients listed in Where to Buy Ingredients. Also, it’s estimated based on 18 bars per recipe.

    I did have a question, can I use honey instead of pure maple syrup?
