Peanut Butter Rice Krispies Cake

1. Prepare the Pans

Butter three 8-inch round cake pans and line them with parchment paper to ensure that the cake doesn’t stick.

2. Make the Rice Krispies Layers

Melt 1 cup of butter over medium heat, cook until it browns and emits a nutty aroma. Turn off the heat and stir in the marshmallows until melted. Add the peanut butter, stirring until smooth. In a large bowl, mix the crispy rice cereal with this mixture, sprinkle with flake salt, and press into the prepared pans. Let it set until firm, about 2 hours.

3. Prepare the Frosting

Melt the bittersweet chocolate and let it cool slightly. In a separate bowl, mix together the sour cream, confectioners' sugar, and sea salt until smooth. Stir in the melted chocolate to create the frosting.

4. Assemble the Cake

Remove the rice krispies layers from the pans and place one layer on a serving platter. Spread frosting over the top, then add the second layer. Repeat with remaining layers and frosting. Finish with a sprinkle of flake salt on top and let the cake sit before serving.
