Microwave Chocolate Snack Cake

Total Time

This is sooo easy and really quite yummmy. It is also nice for small families, because it only makes a small cake. The recipe originally came from Taste of Home and they used a 700 watt oven to test the recipe. Mine is a 900 watt and you just have to adjust the time a bit to accomodate your microwave the first time you make it.

My in-laws gave me a microwave to replace mine that had konked out and I used this recipe to make a 'thank you' cake (since it was made in my present!). ;) My kids (ages 8 & 9) actually did most of the work, which shows how easy it is. All of the chocoholics in the family loved it. Super easy and fast! I baked it for 5 1/2 minutes in the 1100 Watt microwave, in case that's helpful to anyone!

I really enjoyed this cake- but was not crazy about the topping. I had some Pillsbury chocolate fudge frosting the pantry. Wow- this cake with that frosting is soooooo good! Thanks!

Wow this was really good for less than ten minutes of work. I swear I could've eaten the cake batter pre-cooked (I'm odd, I love the combination of the baking soda, vinegar and chocolate). I only "baked" mine for 5 minutes in a 1250W microwave. Came out very moist and chocolatey. Thanks!
