Ingredients
Chocolate brownie
- 115 grams unsalted butter, melted
- 200 grams (1 cup) caster sugar or granulated sugar
- 1 teaspoon vanilla extract
- 2 large eggs
- 1 egg yolk
- 40 grams (1/2 cup) cocoa powder, sifted
- 35 grams (1/4 cup) plain flour or all purpose flour
- 1/4 teaspoon salt
Peanut butter layer
- 60 grams (1/4 cup) unsalted butter, softened
- 250 grams (1 cup) smooth peanut butter, room temperature
- 65 grams (1/2 cup) icing sugar or powdered sugar
Chocolate crunch
- 150 grams (1 cup) good quality dark chocolate, pieces
- 20 grams (1/2 cup) Rice Bubbles or Rice Krispies
- 1 teaspoon vegetable oil or coconut oil, optional
Instructions
- Chocolate brownie
Preheat oven to 180 C (350 F) standard / 160 C (320 F) fan-forced. Grease and line an 8-inch square baking pan with baking or parchment paper, ensuring two sides overhang. - In a large mixing bowl, add melted butter, sugar and vanilla and gently whisk together.
- Add the eggs, one at a time, and the egg yolk. Then add cocoa powder, flour and salt. Stir until just combined.
- Pour the brownie batter in the prepared pan. Bake brownies for approximately 25-30 minutes. Leave to cool completely. If you’re making the brownie ahead of time, cover and place in the fridge.
- Peanut butter layer
To make the peanut butter filling, add butter and peanut butter to a large mixing bowl. Use an electric mixer on medium speed until creamy. - Add sugar and mix again until combined and smooth. Spread peanut butter filling on top of cooled brownie and smooth the top. Pop brownie back into the fridge.
- Chocolate crunch
Heat chocolate in the microwave, stirring every 20 seconds, until melted and smooth. Quickly stir through the rice cereal, until it’s completely coated. Add oil, if using. - Pour the chocolate cereal on top of the peanut butter and spread it out as best you can. Place in the fridge (or freezer) for at least 2 hours or until firm.
- Use a hot knife to carefully cut into small slices to serve.
Notes
Cocoa powder: You can use natural cocoa powder or Dutch processed cocoa powder for this recipe. Don’t use sweetened cocoa powder or drinking chocolate.
Peanut butter: Use a processed full-fat smooth peanut butter, rather than a natural-style one. Examples include Bega, Skippy’s or Jif.
Vegetable oil or coconut oil: A touch of oil will help create a chocolate top that won’t crack when sliced.
Storage: Keep these bars in an airtight container in the fridge.
