 Ingredients & What Each One Does

For the Oat Layer:

• 1 cup unsalted butter – Adds richness and helps bind the oats into a chewy base.

• ½ cup packed brown sugar – Provides sweetness and a subtle molasses depth.

• 1 teaspoon vanilla extract – Enhances overall flavor.

• 3 cups old-fashioned rolled oats – The hearty, wholesome base that gives texture and chew.

For the Chocolate Layer:

• 1 cup semi-sweet chocolate chips – Melts into a fudgy, glossy filling.

• ½ cup creamy peanut butter – Adds creaminess, structure, and nutty flavor to balance the chocolate.

✅ Optional add-ins: A pinch of salt, a handful of chopped nuts, or a sprinkle of sea salt on top for extra flair.

 Step-by-Step Instructions

 1. Prepare Your Pan

• Line an 8×8-inch or 9×9-inch square baking dish with parchment paper, leaving some overhang for easy removal.

 2. Make the Oat Mixture

• In a large saucepan over medium heat, melt the butter.

• Stir in the brown sugar and vanilla. Mix until dissolved.

• Add the rolled oats, and cook for 3–4 minutes, stirring constantly to coat.

• Remove from heat.

 3. Press & Chill the Base

• Press half of the oat mixture evenly into the bottom of the prepared pan.

• Reserve the other half for the topping.

• Place the pan in the fridge or freezer to let the bottom layer firm up slightly while you prepare the filling.

 4. Make the Chocolate-Peanut Butter Filling

• In a microwave-safe bowl, combine chocolate chips and peanut butter.

• Microwave in 30-second intervals, stirring between each, until smooth and fully melted (about 1–2 minutes total).

 5. Layer & Finish

• Pour the chocolate-peanut butter mixture over the chilled oat base.

• Use a spatula to spread it evenly.

• Crumble or press the remaining oat mixture on top.

 6. Chill to Set

• Refrigerate for at least 2–3 hours or until firm enough to slice.

• For faster results, place in the freezer for 1 hour.

 7. Slice & Serve

• Use the parchment overhang to lift the bars out.

• Slice into 16 squares or 12 larger bars, depending on preference.
