It's no secret that I have a major sweet tooth, so making a whole cake for our small household can be a dangerous thing because I'm likely to eat way too much of it. Luckily, I've found an alternative that is cheaper, easier, and just as tasty.
All I do is mix four tablespoons of cake mix with two tablespoons of water in a bowl and then microwave for 45 seconds. I typically add other things to it, but it isn't necessary. My favorite variation is to drop a handful of chocolate chips and dot peanut butter on top of the batter before I microwave it. Or I'll make a basic recipe and then spoon some canned frosting on top of the cake while it's still warm. Really, your only limit is your imagination.
My local grocery store is selling Betty Crocker's Warm Delights for $2.59 this week. I can make the same thing for about $0.10. That's what I call a good deal.
