Ingredients:
- 4 tbsp (56g) unsalted butter
- 1 can (14 oz / 397g) sweetened condensed milk
- 2 tbsp instant espresso powder
- 1 tsp vanilla extract
- 1/4 tsp fine sea salt
- 6 cups (150g) puffed rice cereal
- 1/4 cup (30g) crushed toasted hazelnuts
Instructions:
- Melt the butter in a large saucepan over medium-low heat. Once bubbling, whisk in the instant espresso powder and salt. Heat for 60 seconds until the coffee smells roasted and nutty.
- Pour in the sweetened condensed milk and vanilla extract. Stir constantly with a silicone spatula for 3-5 minutes until the mixture becomes a glossy, mahogany-colored syrup that thickens slightly.
- Remove the pan from the heat immediately. Fold in the puffed rice cereal and crushed toasted hazelnuts, ensuring every grain is evenly coated in the coffee syrup.
- Transfer the mixture into an 8x8 inch baking pan lined with parchment paper. Press down gently with a greased spatula. Let the treats set for 30 minutes before slicing into squares.
