How To Make This Recipe

Prepare the Dish

Line your 9×9-inch baking dish with parchment paper or lightly grease it. This makes removing and slicing the bars much easier.

Cook the Oat Mixture

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

Stir in the brown sugar and vanilla, then mix until smooth.

Add the oats and cook for about 2–3 minutes, stirring often, until the mixture is well combined and coated.

Make the Chocolate Layer

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

Heat in 20–30 second intervals, stirring each time, until smooth and melted.

Layer the Bars

Press half of the oat mixture firmly into the prepared dish.

Spread the chocolate-peanut butter mixture evenly over the oats.

Top with the remaining oat mixture, pressing lightly to cover the chocolate layer.

Chill

Place the dish in the refrigerator for at least 2–3 hours, or until firm.

Slice & Enjoy

Once set, cut into bars or squares. Store leftovers in the fridge for best texture.

Tips + Tricks & More For Recipe Success

Firmness counts – Press the bottom oat layer firmly so it holds together when sliced.

Quick oats vs. rolled oats – Quick oats work best for texture, but you can use rolled oats if you prefer a chewier bite.

Peanut butter options – Creamy peanut butter gives a smooth filling, while crunchy peanut butter adds texture.

Want it sweeter? Add a drizzle of honey or maple syrup to the oat mixture.

Storage tip – Keep bars in the fridge in an airtight container for up to 1 week. They also freeze beautifully for longer storage.

Kid-friendly – This is a perfect recipe for kids to help with since there’s no oven involved.

As a quick after-school snack.

Packed into lunchboxes for a surprise dessert.
