Instructions

  1. Step 1: Line an 8x8 inch baking pan with parchment paper, leaving an overhang for easy removal.
  2. Step 2: In a medium saucepan over low heat, combine 1 cup of natural creamy peanut butter and 1/2 cup honey. Stir continuously for about 3-4 minutes until the mixture is smooth and slightly thinned, then remove from heat.
  3. Step 3: Stir in 1 tsp vanilla extract and 1/4 tsp sea salt into the peanut butter mixture until fully incorporated.
  4. Step 4: Add 2 cups old-fashioned rolled oats to the mixture and stir thoroughly until all oats are evenly coated.
  5. Step 5: In a small bowl, mix 1/4 cup freeze-dried raspberry powder with 1 tsp almond extract and 1/3 cup chopped almonds to create the raspberry almond swirl.
  6. Step 6: Pour half of the peanut butter oat mixture into the prepared pan, spreading evenly with a spatula.
  7. Step 7: Dollop the raspberry almond swirl mixture over the oat base, then gently swirl with a knife to create a marbled effect.
  8. Step 8: Top with the remaining peanut butter oat mixture, pressing down lightly to compact.
  9. Step 9: Refrigerate the pan for at least 2 hours until firm enough to cut into 12 bars.
  10. Step 10: Remove from the pan using the parchment overhang and slice into bars to serve.
