I made half a batch to try this one out. Everything cooked very well, the consistency was good, it was pretty easy to make. All good points. I'm giving it 4 stars for those facts. We did NOT like it for only one fact: It was mega- hugely- super- SWEET! Just way too much for us. I guess we should have figured that out in the beginning considering the full batch uses 6 CUPS OF SUGAR! Wowee! Other people may love super-sweet things, but we don't. I'm not going to take off points for personal preference, as that's not fair. But I don't think we'll make it again.

This was so far from a cake it was pitiful. Several people asked what kind of brownie mix I used! If you want "chewy" fine. If you want a cake keep looking.

It was super quick. I was craving something chocolate and this fixed it. I quartered the recipe and it cooked in 5 minutes. I topped it with chocolate syrup instead of making the frosting. I cooked it in a ramekin and it came ou perfectly. I'm going to try some new variations.

I finally tried this recipe, and the reviews were so right! This cake is so simple to make and it turned out very dense and rich like a brownie. It was almost too chocolately for my tastes but everyone else loved it!! Since it only takes 15 minutes to cook and in the microwave at that, I'm sure I'll be making this on a more regular basis when a quick dessert is necessary.

I tried making this recipe in the oven AND in a muffin pan. I wanted little Mississippi cupcakes, it turned out great. I baked it at 375 degrees farenheit (or Gas Mark 4) for 18 minutes. I also incorporated the mini marshmallows in to the better, I had multicoloured ones and they rose to the top to create a very pretty effect.

Oh so easy!! I've been trying micro dessert recipes lately -- as my sons keep asking after dinner, "What's for dessert?" (been at gramma's too often I think!)Anyway, this one was fast, easy and tasty! It's so nice to be able to throw dessert in teh Micro while the rest of dinner is going! THANKYOU!

This was awesome. My microwave is small so I used a 8 x 8 pyrex pan. Be sure not to overbake or the edges will be hard as a rock. The middle can be a bit gooey. I thought frosting would be overkill, so instead I sprinkled the still warm cake with the mini marshmallows and some chocolate chips. This was amazing spooned into a dessert bowl and served with vanilla ice cream or cool whip. When serving after it has cooled, nuke it a bit first as it is best warm.

This recipe actually turned out great! I was checking out recipes that I can make with my daughter's kindergarten class. I made this by cutting the recipe in half. I sprayed a glass bowl (white Pier One luminous porcelain, a medium size serving dish size) with baking spray. I baked in my microwave for 5 minutes and it was perfectly fluffy and done! I put the new stackable shaped marshmallows on top with some milk chocolate chips and microwaved for 30 seconds or so until slightly melted. I topped with walnuts, chocolate syrup, and whipped cream. I skipped the frosting. Awesome and this recipe will work for the classroom.
