Method
- Step 1: Preheat your oven to 350°F (175°C) and prepare your 9x9-inch baking pan by greasing it or lining it with parchment paper.
- Step 2: In a mixing bowl, combine the creamy peanut butter, powdered sugar, softened butter, and vanilla extract. Mix well until smooth and thoroughly combined.
- Step 3: Pour the peanut butter mixture into the prepared baking pan and evenly spread it across the bottom.
- Step 4: In a microwave-safe bowl, combine the white chocolate chips and vegetable oil. Microwave in 30-second intervals, stirring in between, until fully melted and smooth.
- Step 5: In another microwave-safe bowl, melt the semi-sweet chocolate chips using the same method.
- Step 6: Drizzle the white chocolate over the peanut butter layer in the baking pan, followed by the semi-sweet chocolate.
- Step 7: Using a knife or toothpick, gently swirl the two chocolates together to create a marbled pattern.
- Step 8: Bake in the preheated oven for 20-25 minutes. Keep an eye on the edges, which should turn slightly golden.
- Step 9: Once baked, remove from the oven and let cool completely before slicing into squares.
Notes
For best results, allow the bars to chill in the refrigerator before cutting. This helps them firm up for clean cuts.
