Ingredients For Chocolate Peanut Butter Bars
Base:
• 115g (1/2 cup or 1 US stick) melted salted butter (or unsalted butter with 1/4 tsp salt)
• 1 cup crushed Arnott’s Marie crackers (about 11 crackers) or graham cracker crumbs (from about 8 crackers)
• 1 cup icing sugar (powdered sugar)
• 3/4 cup smooth peanut butter
Topping:
• 1 cup dark chocolate chips (the melting kind—semi sweet works great)
• 2 tbsp smooth peanut butter
How to Make Chocolate Peanut Butter Bars
- Butter and line an 8-inch square dish or pan with baking paper.
- Place the base ingredients in a bowl and mix them until well combined. Then press the mixture firmly into the prepared pan.
- To make the topping, melt the chocolate chips and peanut butter together in the microwave using 2 bursts of 30 seconds. Pour and spread the melted topping over the base; you can smooth it out or create swirls if you like.
- Refrigerate the assembled bars until set, about 1 1/2 hours. Remove them from the fridge and allow a slight warm-up at room temperature so the top cuts neatly, then slice into 16 squares or any shape you prefer.
What to Serve with Chocolate Peanut Butter Bars
These bars are delightful served at room temperature alongside a cup of coffee or a cold glass of milk. They work well as an easy dessert for gatherings or a treat on a cozy day.
Tips For Making Chocolate Peanut Butter Bars
- Ensure the melted butter isn’t too hot before mixing it with the other base ingredients.
- Press the base mixture evenly in your pan for a firm foundation.
- When melting the topping, work in short bursts to avoid burning the chocolate or peanut butter.
- Allow the bars to chill completely so the layers set well before cutting.
