Ingredients:
- 6 tbsp (85g) unsalted butter
- 1 tsp (5ml) vanilla extract
- 10 oz (280g) mini marshmallows
- 6 cups (1L) Rice Krispies cereal
- ½ tsp (3g) flaky sea salt
Instructions:
- Place 6 tbsp (85g) unsalted butter in a large heavy bottomed pot over medium heat. Melt and stir constantly until the butter foams, subsides, and small brown specks form at the bottom with a toasted hazelnut aroma.
- Immediately remove from heat and stir in 1 tsp (5ml) vanilla extract. Note: Adding vanilla now prevents the alcohol from evaporating too quickly.
- Turn the heat to low and add 10 oz (280g) mini marshmallows. Stir gently and consistently until the marshmallows are just melted and smooth.
- Remove from heat the moment the last lump disappears. Note: Overheating here leads to rock hard treats.
- Remove the pot from the heat entirely. Gently fold in 6 cups (1L) Rice Krispies cereal using a rubber spatula until every piece is evenly coated.
- Transfer the mixture to an 8x8 inch baking pan lined with parchment paper.
- Use your fingers to gently press the mixture into the corners without packing it down firmly.
- Sprinkle ½ tsp (3g) flaky sea salt evenly across the top while the mixture is still tacky.
- Allow the treats to set for 30 minutes before slicing into 16 squares.
