I'd love to do this, but I just can't. Cereal is for breakfast only for me.
Ben & Jerry's came out with single serve cups of their most popular flavors. I buy the vanilla, cookie dough, and fudge brownie flavors. They're right around 200 calories each, give or take a few, and satisfy my ice cream craving while allowing me a dessert I love. They're also about $1 each, which satisfies my budget requirement as well.
