Ingredients
- Base:
- 65g unsalted butter
- 230g mini marshmallows
- 110g Rice Krispies cereal
- Caramel:
- 90g unsalted butter
- 100g light brown sugar
- 1 tin (397g) condensed milk
- 1 tbsp golden syrup
- 1/2 tsp salt (or more, to taste for a saltier caramel)
- Topping:
- 250g milk chocolate
- 15g unsalted butter
Preparation
Step 1: Prepare the Base. In a large microwave-safe bowl, melt the butter. Once melted, add the mini marshmallows and microwave in 30-second intervals, stirring in between, until completely melted and smooth.
Step 2: Combine Base Ingredients. Immediately pour the melted marshmallow mixture over the Rice Krispies in a large bowl. Gently fold until the Rice Krispies are evenly coated.
Step 3: Press into Pan. Line an 8×8″ or 9×9″ baking pan with parchment paper, leaving an overhang on the sides for easy removal. Press the Rice Krispie mixture firmly and evenly into the prepared pan. Set aside.
Step 4: Make the Caramel. In a medium saucepan, combine the butter, brown sugar, condensed milk, golden syrup, and salt. Cook over medium heat, stirring constantly, until the butter is melted and the sugar is dissolved.
Step 5: Cook the Caramel. Continue cooking the caramel, stirring continuously, for 10-15 minutes, or until it thickens and turns a rich golden brown color. To test for doneness, drop a teaspoon of the caramel into a glass of cold water. If it forms a soft ball that you can easily mold with your fingers, it’s ready.
Step 6: Pour Caramel over Base. Immediately pour the hot caramel evenly over the Rice Krispie base. Spread it out to the edges.
Step 7: Make the Chocolate Topping. In a microwave-safe bowl, combine the milk chocolate and butter. Microwave in 30-second intervals, stirring in between, until the chocolate is completely melted and smooth.
Step 8: Spread Chocolate Topping. Pour the melted chocolate over the caramel layer and spread evenly.
Step 9: Chill and Cut. Let the bars set at room temperature for at least 2-3 hours, or in the refrigerator for about 30 minutes to speed up the process (note: refrigerating might make the base slightly harder). Once set, lift the bars out of the pan using the parchment paper overhang. Cut into squares using a sharp knife.
