This treat combines rich, nutty browned butter with creamy dulce de leche, creating a deliciously indulgent twist on classic Rice Krispie Treats. You'll love the warm, caramel flavor that lingers long after the last bite!
Melt the butter gently in a heavy-bottomed pan, swirling it until it cooks evenly. Pay attention to the color and aroma to achieve perfectly browned butter.
Add the mini marshmallows to the warm brown butter, stirring until melted and smooth.
Gently fold in the crisped rice cereal until evenly coated. If using, fold in the vanilla extract.
Drizzle in the warm dulce de leche and gently fold to create marbled swirls.
Spread the mixture evenly into a prepared pan, pressing down firmly with a greased spatula.
Let the pan rest at room temperature, then refrigerate until fully set before cutting into squares.
Notes
Tip: If your bars are too sticky, refrigerate them longer or press the mixture more firmly into the pan to help them set properly.
