Ingredients
Method
Making the Caramel
- Heat sugar in a heavy-bottomed saucepan over medium heat without stirring.
- Allow sugar to melt around the edges, gently swirling the pan to distribute heat.
- Continue swirling until all sugar melts into an amber liquid, about 8-10 minutes.
- Remove from heat and carefully add butter; it will bubble vigorously.
- Stir until butter is melted, then gradually pour in heavy cream while stirring until smooth.
- Add vanilla and salt into the mixture, stir well, and let cool for 10 minutes.
The Rice Krispie Base
- Melt butter in a large pot over low heat, making sure not to brown it.
- Add marshmallows and stir constantly until fully melted.
- Once smooth, remove from heat and stir in vanilla and a pinch of salt.
- Fold in the Rice Krispies cereal until fully coated, working quickly before it sets.
Assembling the Treats
- Grease a 9×13 baking pan generously with butter or cooking spray.
- Press half of the Rice Krispie mixture into the bottom of the pan firmly and evenly.
- Pour the cooled caramel over the Rice Krispie base and spread to the edges.
- Top with the remaining Rice Krispie mixture, pressing down gently to cover the caramel.
- Immediately sprinkle flaky sea salt over the top.
Cutting and Storing
- Allow the treats to cool completely before cutting, about 1 hour.
- Use a sharp knife dipped in hot water for clean cuts, wiping it between slices.
- Store in airtight containers at room temperature for up to 5 days, with parchment paper between layers to prevent sticking.
Notes
These treats can be made up to 3 days ahead, but don't add the salt topping until the day you serve them to prevent sogginess. They taste best after a day as the flavors meld.
