I love "happy" mistakes like that!
My friend (also on IP) was just given a "chocolate mug cake" recipe that uses the drink by her coach. I mentioned that I have made the pudding cakes before, but had never tried it with the drink.
Here's that recipe:
1 pkg. chocolate drink
1 egg white
1 tsp baking powder
1 tsp olive oil
1 tsp splenda or stevia
1 splash vanilla
Put the powdered drink mix into a BIG mug or bowl. Add enough water to bring it to a slighly watery pudding consistency (4-6 oz). Add all the other ingredients, and mix well until silky smooth (the recipe says use a fork, but a blender or magic bullet would probably work very well). Put the mug or bowl in the microwave for about 3 minutes on top of a big plate. The cake will expand while cooking and contract while cooling.
The only drawback is that it uses 1 tsp of your olive oil allotment for the day. Apparently, you have to put it in a really big mug or bowl and be sure to put the plate under it because it may overflow if your mug or bowl is not big enough.
I may make this for my snack today!
