Found a similar recipe on MyFitnessPal - but as usual - I tweaked it and made it my own. The original also did not include any protein powder! This was obviously something the original recipe was LACKING, and so of course I had to make it more worth the calorie bang!! Here goes.
1 can pure pumpkin (15oz) (I used Libbys)
2 scoops vanilla protein powder (I used Body Fortress)
1tsp Pumpkin Pie spice
3 large eggs
4tbsp liquid egg whites
8oz fat free cream cheese (softened
12 tsp (or 1/4 cup) truvia baking blend
Preheat oven to 375.
Whisk egg whites & eggs together. Combine all ingredients in large bowl and mix well. Spray baking dish with non-stick cooking spray.
Pour into baking dish.
Bake 40-60 minutes (depending on what dish you use -- a deeper loaf pan will have to bake longer) -- test middle for done-ness with toothpick.
Makes 6 slices.
