Remember the quinoa version of this healthy Single-Serving Chocolate Buckwheat Protein Cake from Tuesday?  Remember how I told you that took, um, fourteen trials to perfect?  What I didn’t explain was how many different flours, ingredient combinations, and baking temperatures I used for testing.  I guess I should explain them a little more…

For trials #1-7, I used unflavored protein powder, a flax egg and experimented with baking powder levels.  I wanted these cake bakes to serve as a blank canvas for toppings like nut butters, fruits, spreads, etc, however they were flavorless beyond belief and pretty mushy.  I found that a blank canvas isn’t very good for people on the go or in a hurry with no time to sit down to add their own toppings.  I experimented with different sized baking pans such as ramekins, mini loaf pans and a 5″ baking dish (the 5″ dish won).  I also experimented with different oven temperatures, but 350 seemed to be the easiest and fastest.  Too high of a temperature and the bakes would form a dry “crust” and still be mushy in the center.

For trials #8-12, I wished the “science of baking” was a person so I could punch it in the face.  But instead, I finally got a clue and stopped using the unflavored protein powder.  In these trials I used chocolate protein powder, alternated between rice flour, quinoa flour and buckwheat flour.  I was still working on the flax eggs by experimenting with the baking powder levels.

For trials #13 and 14, I really wanted to punch baking in the face, but just started using real eggs (I found out that I’m allergic to chicken eggs so I used duck eggs instead).  The egg created the best texture of all, but I will still shoot for making a vegan version.  Trial #13 was a success, which was the quinoa flour version.  Trial #14 was this buckwheat version, to make a healthy chocolate buckwheat cake!

I usually like to bake off two or three of these healthy Single-Serving Chocolate Buckwheat Protein Cakes at the same time so I don’t have to use the oven on a daily basis.  Once the extra chocolate buckwheat cake has cooled I wrap it with plastic wrap and leave it on the counter for the next morning…  it gets even more moist and chocolatey!

This healthy Single-Serving Chocolate Buckwheat Protein Cake is just as delicious as the quinoa flour version!  The flavor of this cake is almost exactly the same as the quinoa flour version, but I would say that the buckwheat flour is a little less nutty and more mild than the quinoa flour.



With love and good eats,

  1. Can I use honey?? How many spoons??

    Loooooooove your site, I’m a huge fan!!! Thanks!!!

  2. I love buckwheat! On Saturdays I always make buckwheat pancakes with raspberries. Soo good!

  3. I love that you could have used the same photo for these two posts and no one will ever know..

  4. Hi, can i substitute the brown rice protein for a whey/casein blend?

    • From my experience with both protein powders, I know that in most cases, they are not interchangeable. But, I haven’t tried it in this exact recipe so I can’t be 100% sure. If you feel like testing it out, go for it! I’m crossing my fingers it works 😀

  5. Hi Jessica – I have a question. How do I double this recipe (or increase quantity in general) if I am looking to bake a bigger batch? Thank you 🙂

  6. If you want to make a dozen cupcakes, how much do you increase recipe? Appreciate any recipes with high protein, low carbs, thanks

    • This cake is a pretty generous serving, so I’d say one cake can make about 1.5-2 standard cupcakes. Try multiplying the ingredients by 8:
      240g (2 cups) Buckwheat Flour
      168g (8 scoops OR 1¼ cups, lightly packed) Chocolate Brown Rice Protein Powder
      ½ cup Unsweetened Natural Cocoa Powder
      ⅔ cup Truvia Spoonable
      4 tsp Double-Acting Baking Powder
      1 tsp Salt
      8 Jumbo Eggs
      2⅔ cups Unsweetened Vanilla Almond Milk

  7. I have tried them and they are YUMMMMMMYY!!

  8. Hi! This is look so yummy and healthy. great idea for diet5 stars
