Esta Pastel de proteínas is a high-protein, moist chocolate birthday cake perfect for a healthy celebration. It’s packed with 15 gramos de proteína per serving, with no eggs, and no dairy, and it’s topped with the best creamy smooth chocolate protein frosting.
We love high-protein recipes, and we have shared so many, like my Bolitas de proteína de fresa, Protein Oatmeal Cookies o Avena nocturna con proteína en polvo. Our most popular are the barritas de proteinas caseras o nuestra protein powder mug cake.
This protein cake recipe is inspired by our protein powder mug cake, usually microwaved in a ramekin. Here we turned the recipe into a family-size protein cake recipe, a larger version of our favorite protein snack, baked in less than 25 minutes for a quick healthy cake.
If you love a moist, fudgy chocolate cake but want to keep it healthy and packed with wholesome ingredients, this protein cake is what you need.
Ingredientes y sustituciones
All you need are a few simple ingredients:
- Harina de avena – Oat flour is simply made from rolled oats pulsed into a thin flour-like texture. Check my tutorial on cómo hacer harina de avena si lo necesitas.
- Chocolate or Vanilla Protein Powder – We use clean pea protein powder made with just three ingredients. You can also use almond protein powder or peanut protein powder.
- Cacao en polvo sin azúcar – I prefer to use unsweetened cocoa because it makes it easier to balance the sweetness.
- Leche vegetal de su elección – Soy milk is high in protein, but almond milk or oat milk are also great options.
- Levadura en polvo – This gives the cake a soft and fluffy texture.
- Yogur de tu elección – High-protein soy yogurt is our favorite. It also works with cashew yogurt and coconut yogurt, but the latter gives the cake a slight coconut texture.
- Jarabe de arce – Any liquid sweetener works, such as coconut nectar, agave syrup, or rice malt syrup. Sugar-free alternatives also work.
How To Make A Protein Cake
This protein cake recipe is very easy to put together and perfect to fix your sweet tooth with no guilt.
- Preheat the oven to 350°F (180°C). Line a 9-inch round cake pan with parchment paper and lightly oil it with an oil spray. Set it aside.
- In a large mixing bowl, whisk all the dry ingredients: oat flour, protein powder, cocoa powder, and baking powder. Make a well in the center of the dry ingredients and add dairy-free milk, yogurt or applesauce, vanilla extract, maple syrup, and vanilla extract.
- Stir to bring all the ingredients together and form a smooth cake batter.
- Pour the batter into the prepared cake pan and bake in the center rack of the oven for 25 to 30 minutes at 350°F (180°C) until a pick inserted in the center of the cake comes out clean.
- Cool completely at room temperature before frosting.
Glaseado de proteínas
To frost this healthy dessert, we use our creamy protein frosting recipe made from:
- Yogur Griego – We use plant-based Greek style yogurt, feel free to use any yogurt you love.
- Proteína en polvo
- Leche de almendras
- Jarabe de arce
Stir the ingredients until the frosting is thick and creamy. Spread on top of the cooled cake. Decorate the cake with sprinkles if you like.
Instrucciones de almacenamiento

Intercambios para personas con alergias
If you have some food allergies, pick some of the options below:
- Baja en carbohidratos – You can use a low-carb protein powder and low-carb sweetener for this recipe.

Preguntas frecuentes
Find below my answers to the most common questions on this recipe.
We recommend using clean protein powder. It means protein powders with minimal ingredients listed in the ingredients list for a healthy cake. We use a pea protein powder that contains only three ingredients: natural flavor, pea protein, and a low-carb sweetener. Feel free to use hemp, peanut, or soy protein powder. Note that this recipe hasn’t been tested with an animal protein powder like whey protein or casein, and we can’t recommend these options.

Great soft, silky texture. Delicious.
I am so glad you love them!
I’d love to make this but i’m not a huge fan of chocolate. Is there any way to make this vanilla? I thought about omitting the cocoa powder and replacing it with something else? I’m not sure what would be a good replacement and how to adjust?
It’s very hard to omit cocoa here as it acts as a binder, the fibers in the cocoa bind the cake. You will need something similar, but it might also change the texture too much. I haven’t tested a protein vanilla cake so I can’t tell you more i am sorry.
This cake is so incredibly delicious! Perfect texture, amazing flavor, and healthy too! Definitely making it again!!
¡Muchísimas gracias por sus amables comentarios!
I’m excited to try this, but I’m curious about the kind of protein powder to use. We have a vegan protein powder but it’s sweetened with stevia, as many protein powders do. Does the protein powder you’re using have a sweetener in it? Is that how the recipe is meant to work with 1/3 c. maple syrup? Thanks!!
Estoy utilizando NuZest protein powder, it exist in vanilla, chocolate, strawberry. It’s made of pea protein powder, natural vanilla flavors, and thaumatin – a natural sweetener.
¡Gracias por compartir esta receta!
I can’t wait to try.
Can I use a 6inch tin instead?
Sure, but the smaller the pan is the longer it takes to bake.
Hi! Can i use pea protein powder here?
¡Por supuesto!
This was such a hit!! I baked two 9 inch layers though (I didn’t double the recipe because I decided to do a 2nd layer after I poured the batter into the 1st pan) and then doubled the frosting recipe. I put a layer of bananas in the middle of the cake plus frosting and then frosting all over the two layers, plus rainbow sprinkles. It was SOOOOOOO GOOD!!! Wish I could post a pic!
Looks delicious! Can’t wait to try it.
I have a severe oat allergy is there another option?
I didn’t try something else yet, may be all-purpose wheat flour could work as well.
