These triple chocolate protein cake bars are a high protein snack with three different kinds of chocolate making each bar feel indulgent yet healthy.

Want to know the secret to having consistent motivation to workout?

Things like this protein cake recipe waiting for you either pre or post exercise.

I’m not even kidding when I tell you my mood went from slightly dreading my workout for the last two days (only because of the length of these phase 2 livefit workouts, not because I don’t like the program) to full out excited when I remembered these protein bars were in the fridge.

When chocolate is involved, that kind of thing happens I guess.

See this chocolate baked oats recipe for more proof.

These triple chocolate protein cake bars are a high protein snack with three different kinds of chocolate making each bar feel indulgent yet healthy.

It’s a sad thing to come home to an empty fridge after traveling, but it’s a whole other level of sad/difficult/frustrating to not have any good prepped workout food on hand.

Post-workout high protein “fun” snacks (like these high protein cinnamon cake bars) are the main thing that gets me through workouts some days.

If I’m going to be anywhere near successful in eating well and focusing on protein content, I need stuff on hand and ready because if I come up the stairs from our gym in the basement (currently inhabited by a rogue cricket who will not shut the hell up as I type this from a level above him) without a post workout snack planned out, things go south quickly.

It just so happens that these planned protein cake snacks have 3 different kinds of chocolate going on with their 10 grams of glorious protein a piece.

Funny how that happened, huh?

If Jamie Eason is going to superset me to death for an hour and a half, you can bet there will be more of this chocolate protein cake being made for the remainder of phase 2.

I can be bribed with anything with cake in its name.

Chocolate is just an added bonus.

These vegan black bean brownies also work as a bribe. A high protein brownie? Yep!

Oh, and peanut butter on top?

It’s protein too so why not, right?

I can't for the life of me find any NuNaturals stevia baking blend. What could I use instead? Or perhaps how much sugar do you think it would call for, then I can use a conversion chart for whatever substitute I do find.

Your best bet for stevia baking blends (doesn't have to be NuNaturals) would be Amazon. But you can use any sweetener you like (coconut sugar would be my choice of substitute) just like the notes at the bottom of the recipe say.

I'm going to try and make these Vegan by substituting Flax egg and Vegan yogurt. See any problems with that you'd like to point out?

I haven't tried this recipe with vegan substitutes and I've never baked with vegan yogurt before so I really can't tell you what to expect. Hope they turn out!

Just tried this tonight. I slightly overcooked mine I think. Outside was just a little hard. I was using vegan powder so I suppose that's why. Otherwise it was great. Thanks for the recipe. Finally a good recipe with things i actually keep on hand. Can't wait to make it again with the time reduced.

Could the oat flour possibly be substituted with amaranth flour?

Running to the Kitchen

Friday 20th of October 2017

That's not a substitution I've tried so I can't say for sure. Oat flour is a pretty "normal" flour but I'm not sure how amaranth flour reacts.

Looks great, would this work with coconut flour?

Running to the Kitchen

I haven't tried it with coconut flour. You could probably use 1-2 tablespoons of coconut flour in place of the almond flour but not as a substitution for the oat flour, they're just not comparable.
