Instructions
- Step 1: Line an 8x8-inch square pan with parchment paper, allowing edges to overhang for easy removal. In a medium saucepan, melt 1 cup natural creamy peanut butter, 1/2 cup honey, and 2 tbsp unsalted butter over low heat, stirring continuously until smooth and well combined, about 3 minutes.
- Step 2: Remove the peanut butter mixture from heat and stir in 1 tsp vanilla extract and 2 cups old-fashioned rolled oats until fully coated and sticky.
- Step 3: In a small bowl, combine 1/4 cup crushed freeze-dried raspberries with 2 tbsp powdered sugar, then sprinkle half of the mixture evenly over the bottom of the prepared pan.
- Step 4: Spread half of the oat and peanut butter mixture evenly over the raspberry layer, then sprinkle the remaining raspberry mixture on top. Using a butter knife, gently swirl the layers together to create a marbled effect.
- Step 5: Press the remaining oat mixture on top and refrigerate the pan for at least 2 hours until firm. Use the parchment edges to lift the bars out and cut into 12 squares before serving.
