Why make a bunch of treats when making one is just as easy? Within a few short minutes, you can have your own personal rice krispie treat in a mug. Gooey, sweet, and the perfect treat or late night snack.
Melt butter. Add butter to a 12 to 16-ounce microwave-safe mug. Microwave 10 to 15 seconds until just melted. Swirl butter around the sides of the mug to lightly coat.
Melt marshmallows. Add marshmallows to the mug. Microwave 30 seconds until puffy and melted.
Stir. Stir immediately to fully combine melted butter and marshmallows.
Add cereal. Stir in ½ cup cereal until coated. Add up to ¼ cup more cereal for a firmer texture.
Set or eat. Enjoy immediately for a warm, gooey treat, or let rest 1 to 2 minutes for a softer texture. Let rest about 5 minutes to press into a square or bar.
Notes
Microwave Tip. Avoid overcooking or over-stirring. Melt just until soft to prevent hard treats once cooled.
Texture Control. Less cereal makes it gooier, more cereal makes it firmer.
Toppings. Add sprinkles, chocolate chips, crushed cookies, or a drizzle of melted chocolate if desired.
Storage. Store airtight at room temperature up to 2 weeks or freeze individually wrapped portions up to 3 months. Thaw at room temperature before eating.
