Line a baking pan

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

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 finicky 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.

Ingredients

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.

  1. I love this recipe so much! It makes a great afternoon snack for my son.
    I did have a question, can I use honey instead of pure maple syrup?
