Have a craving for Rice Krispie Treats, but don't want to make a whole pan of them? This Rice Krispie Treat in a mug is single serving and needs only 3 ingredients, 2 minutes and a microwave. One Rice Krispie Treat, just for you!
In a microwave-safe mug (preferably 12 ounces) or small bowl, add butter and microwave for 15-20 seconds or until just melted. Tip the mug slightly to the side and roll the melted butter around to coat the edges a bit.
1/2 Tablespoon unsalted butter
Add marshmallows and microwave again for 30 seconds. Carefully remove from microwave and stir to combine. Immediately add Rice Krispies cereal and stir to combine. Start with 1/2 cup, then add up to another 1/4 cup more if you'd like it thicker.
6 large marshmallows, 1/2 to 3/4 cup Rice Krispies cereal
If you want to make a single serving Rice Krispie treat square, press it into a square shape on a plate and let it set for a few.
Serve and enjoy!

Notes
Cereal to marshmallow ratio: Start with 1/2 cup of Rice Krispies cereal at first, then add more if you want it to be thicker. I prefer my ratio of cereal to marshmallow to be more marshmallow-heavy, and it's also easier to eat with a spoon.Mug size: You want your mug to be at least 8 ounces, but preferably 12 ounces.Microwave wattage: My microwave is 1500 watts, so you may need to adjust your time to be less or more depending on the wattage of your microwave.
