After many many trials, I finally found a dairy-free whipped cream recipe that actually tastes really good. The one I posted on here before tasted good mixed in with other things, but not by itself. This one I was having a hard time not eating it with a spoon!
~ 1/2 cup soy milk
~ 1 cup powdered sugar
~ 1 teaspoon vanilla
~ 3/4 cup vegetable oil
1. Combine soy milk, powdered sugar, vanilla and 1/2 cup vegetable oil in blender.
2. Add remaining (1/4 cup) vegetable oil.
3. Blend until it has a consistency similar to "real" whipped cream.
4. Taste it to make sure that it is sweet enough, and add more of necessary ingredients. Depending on the soy milk you use, you may need to add more sugar and/or vanilla.
