Microwave Chocolate Snack Cake

"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!

    Usually when I make this cake I cut it down to three servings and reduce the cooking times, especially with the frosting. It's great for a quick, easy dessert. I once made it with a group of kids that I was tutoring to introduce them to fractions, and they were surprised that you could actually make a cake in the microwave, and quite impressed with the result.

    A great and quick fudgy little cake. DH was bemoaning our lack of dessert one night so while he was busy with the computer I whipped this up. Took him a plate of warm cake and he was amazed. The only small addition I made was to add about 1/2 c of semi-sweet chocolate morsels to the cake batter before cooking it since DH always thinks everyting needs "a little more chocolate." The sauce to me was reminiscent of Sanders' Swiss Chocolate topping. I'll make this again when we need a quick dessert or someone has a major chocolate attack!
