Brownies

2 eggs
3 scoops whey protein powder (vanilla)
1 stick butter
1/2 cup sweetener (I use liquid sweet n low)

Melt butter, add eggs, whey protein powder and sweetener. Mix well and put in a 6x6 baking dish. Cook on 325 for about 15-20 minutes. Makes 9 servings. Each serving has about 1g carb per piece, depending on the whey protein powder you use.
Counts per batch: Cal:1347 Fat:364 Carb:8.8
Per 1/9th: Cal:150 Fat:40.4 Carb: 1

For the chocolate:
2 eggs
2.5 scoops whey protein powder
2 tbsp unsweetened cocoa powder
1 stick butter
1/2 cup sweetener

Per Batch: Cal:1322 Fat:364 Carb:13.3
Per 1/9th: Cal:147 Fat:40.4 Carb:1.5

Edited to add: If you want these less cake like and more hard and portable and "bar like" only use 1 egg. The counts for the recipe this way is:
Per Recipe: Cal:872 Fat:312.8 Carb:8.8
Per 1/9th: Cal:96.9 Fat:34.76 Carb:1

I used the Body Fortress brand at Walmart but if you used Jay Robb or another lower carb brand they wouldn't even have that many carbs! The Jay Robb brand would reduce the carbs from 8.8 to 3.8.
