1-First, lightly grease a 13×9 inch pan with butter or line it with parchment paper to keep things from sticking. This simple step makes cleanup a breeze and ensures your treats come out perfectly.

2-Next, melt the 6 tablespoons (85 g) of salted butter in a large saucepan over medium-low heat, stirring occasionally until it’s fully melted that’s your flavorful base right there.

3-Once the butter is melted, add 10 oz (about 5 ½ cups) of the miniature marshmallows and stir until just melted, keeping the heat low to avoid any separation. Stir in the 1 teaspoon of pure vanilla extract for that extra flavor boost. Then, add the 6 cups (175 g) of Rice Krispies cereal along with the remaining 5 oz (about 2 ½ cups) miniature marshmallows, folding gently so the marshmallows start to melt just a bit without over-mixing.

4-If you’re adding the 3 tablespoons of colored sprinkles, mix them in briefly or sprinkle them on top once the mixture is in the pan. Quickly transfer everything to your prepared pan and gently pat it down evenly don’t pack it too tightly, or your treats might turn out hard instead of soft. Finally, let it cool at room temperature for 30 to 60 minutes before cutting into squares. For a related treat idea, check out our baked oatmeal cups recipe for another easy breakfast option.
