4. Slice into neat bars and serve.

Step-by-Step Recipe Preparation Method

Step 1: Prepare the Base Layer

1. Preheat oven to 350°F (175°C) and line an 8×8-inch square baking pan with parchment paper.
2. In a bowl, combine melted butter, brown sugar, oats, flour, and salt.
3. Mix until crumbly but well combined.
4. Press the mixture firmly and evenly into the prepared pan.
5. Bake for 20–25 minutes, or until the edges are lightly golden.
6. Let it cool completely before adding the next layer.

Step 2: Make the Peanut Butter Layer

1. In a medium bowl, whisk together peanut butter, powdered sugar, and vanilla extract until smooth and creamy.
2. Spread evenly over the cooled crust using a spatula.
3. Place in the refrigerator for 10–15 minutes to firm up slightly.

Step 3: Prepare the Chocolate Layer

1. In a microwave-safe bowl, melt chocolate chips and 2 tablespoons peanut butter together in 20-second intervals, stirring after each until smooth.
2. Pour over the chilled peanut butter layer and spread evenly.
3. Tap the pan gently to remove air bubbles.

Step 4: Chill and Slice

1. Refrigerate for at least 30–40 minutes, or until the chocolate is fully set.
2. Use the parchment paper to lift the bars out of the pan.
3. Slice into squares or rectangles using a sharp knife (warm the knife slightly for clean cuts).

How to Serve

• Sprinkle a pinch of sea salt on top for a gourmet touch.
• Pair with coffee, milk, or hot chocolate for a cozy treat.
• Serve on dessert platters or in mini cupcake liners for parties.

Additional Recipe Tips

• Use good-quality chocolate chips for a smoother, shinier finish.
• For extra crunch, mix chopped peanuts or crushed pretzels into the peanut butter layer.
• Chill the bars well before slicing for clean, even edges.
• Use natural peanut butter if preferred, but make sure it’s not too oily.
• Add a drizzle of white chocolate on top for a pretty contrast.
