For Claudia

Per request, here is a rough outline of how I make my baked protein goodies.  I tweak based on my mood, what ingredients I have on hand, and how the mix looks.  If I'm making pancakes, I add more liquid, less for muffins and mini loaves. I generally eat these for breakfast, or a pre-workout snack.  These fit my macros well, and are fairly low calorie. You can use more protein powder and up the wet ingredients accordingly to increase the protein content & calories.

The following is for an individual serving, generally one loaf or two jumbo muffins.  Or you can make it in a mug and microwave it for a few minutes.  Easy peasy.

DRY
2 tbsp coconut flour
1 tbsp oat flour
1 tbsp (.25 scoop) protein powder of choice.  (I've been using either Nutrabolics Iso in Cinnamon Oatmeal or Cellucor Whey Molten Chocolate a lot lately.)
2 to 3 packets stevia (yes, I have a sugar problem)
pinch of baking powder (1/4 tsp?)
*If I'm making a chocolate one, I'd add 1 tbsp Hershey's baking cocoa
*Don't need salt if you're using protein powder; it's in there
Mix dry ingredients

WET
3 to 4 tbsp liquid egg white
1/4 cup pure pumpkin puree OR 1/3 medium banana (melt banana in microwave for easy mashing)
*I choose based on the flavor I'm going for.  With chocolate, either works.  For berry, the banana is best.  Either is good alone.  If you're using berries, add 1/4 cup frozen mixed berries & microwave with banana.
Splash of vanilla /butter/maple/extract of choice
1/4 to 1/2 cup milk of choice (Water works, too.)
*Note about the milk:  when baking with coconut flour, you generally need more liquid.  I don't measure, I just eyeball it.  Let the mix sit for a minute or two, as the flour will continue to absorb.  
Add to dry ingredients and mix.
Adjust to desired consistency.
*Lately, I've been adding a splash of apple cider vinegar to activate the baking powder; it makes them fluffier.  I only do this for the muffins or loaves.

Bake at 375* for 30 to 35 minutes.  I start checking it around 30 minutes.  The longest I've had to bake them was 40.  If you're making a mug cake, it's about 2 to 3 minutes, depending on the strength of your microwave.

If you'd like a topping, here are some suggestions:
Walden Farms syrups
Protein sludge (Protein powder mixed with a small amount of milk)
Greek yogurt with protein powder blended in.  Or, if you eat it, Jello Pudding Sugar Free mix, 1 tbsp., when blended into yogurt, turns into something with a consistency VERY similar to frosting.  It's just not "clean" if you care.
Laughing cow light original with a packet of stevia and a splash of milk, microwaved briefly and blended together
Melted banana/berries
