Okay, this one's good, and it's really low in calories. Here's the gist.
1 spice cake mix (Betty Crocker Super Moist) - pick the one with 160 calories per serving
1 can (15 oz) pumpkin pack
1 tsp pumpkin pie spice.
Yep, just mix these three together and then bake according to package directions. DO NOT add eggs or oil. You can add some water to the batter to get it to a thinner texture. You will probably have to bake just a little longer than the package says. Easy.
8 oz. Neufchatel cheese
1 cup powdered sugar
1 tsp. vanilla
Yep, just mix and go. You can add a tablespoon of milk or so if you need.
Calories? 234 for a 12th of the cake. That's a pretty big serving of cake for not very many calories. Want some variation? Leah and I also tried using a chocolate cake mix and omitted the pumpkin pie spice. We added just a little more cocoa powder and it was wonderful.
