Baked a delicious, warm and spiced carrot cake made with oat flour and protein powder. It is high in protein, low-calorie, and gluten-free.
If someone told me I could have carrot cake that’s high in protein, nutritious, and gluten-free about 10 years ago, I wouldn’t have believed them. Surely, that couldn’t have tasted good.
Well, funnily enough, because the desserts I make these days are so satisfying and macro-friendly. My friends agree.

I have made these in one of the dinners I’ve hosted for my friends and family enjoyed this cake at a recent gathering. 4 hours a day!

Ingredients and Substitutes
DRY INGREDIENTS
Oat flour (1 cup) – Substitute with almond flour or gluten-free all-purpose flour if you don’t have oat flour.
Rolled oats (1 1/2 cups) – You can also use quick oats.
Hydrolyzed collagen, or protein powder (1/2 cup) – I love using vanilla-flavored protein powder since it adds a bit more flavor to the recipe, but you can use unflavored protein powder or collagen powder.
Baking powder (1/2 tsp)
Ground cinnamon (1 tsp)
Ground nutmeg (1/8 tsp)
Cardamon (a pinch)
Sea salt (a pinch)
WET INGREDIENTS
Egg (1 large) – If you want to make a plant-based version, use a flax egg (1 tbsp flaxseed + 3 tbsp of water).
Banana, ripe and mashed (1 large) – You can use applesauce if you don’t have (or like) bananas.
Maple syrup (1/2 cup) – Swap for honey, agave syrup, or a sugar-free option if you don’t have maple syrup.
Oat milk (1/4 cup) – Switch it up with almond milk or regular milk.
Coconut oil, melted (3 tbsp) – You can also use butter, ghee, or avocado oil.
Carrots, grated (2 medium) – This is the star ingredient of the cake; there is no replacement here.
Pecans, chopped (1/2 cup) – Walnuts make a perfect substitute.
FROSTING
Cottage cheese, low-fat, blended (1 cup) – Plain Greek yogurt or cream cheese can be great alternatives.
Maple syrup (2 tbsp)
Carrot, grated

How to Make Moist Protein Carrot Cake
Step 1. Preheat your oven to 350°F. Grab a baking dish (I used a 7×10-inch pan) and cover it with parchment paper and spray it with oil.
Take a large bowl, and add all the dry ingredients.
Step 2. Give all the ingredients a good stir.

Step 3. In another bowl, add all the wet ingredients and give them a good stir.
Step 4. Combine the dry and the wet ingredients. Give it a good mix to form a thick batter.

Step 5. Add the carrots and pecans.
Step 6. Give the mix a good stir.

Step 7. Pour the mix into the baking sheet and level it out with a spatula.
Step 8. Place in the oven and bake for 20-25 minutes.

Step 9. Take the cake out of the oven and let it cool down. Remove from the baking dish by pulling the sides of the parchment paper.
In a bowl, mix the cottage cheese with the maple syrup. Now, use the frosting to cover the entire cake.
Step 10. Sprinkle the cake with the grated carrots.

Step 11. It’s time to eat! You can serve it immediately or store it in the fridge to have later.

Pin ItHow I Modify This Recipe
- Make it Vegan: Swap the egg with flax egg, choose a plant-based protein powder, and replace the cottage cheese with silken tofu.
- Low–Carb Option: Replace the maple syrup with a keto-friendly or sugar-free option like monk fruit or erythritol.
- Nut–Free Option: Swap the pecans with sunflower seeds or shredded coconut.
- Boost the Flavor: Add other ingredients like raisins, dried cranberries, orange zest, and shredded coconut.
My Tips & Tricks
- Use Fresh Carrots: Grating your carrots fresh rather than using pre-shredded ones gives them more moisture and better flavor.
- Don’t Overmix: Once you combine the wet and dry ingredients, mix them gently to avoid a dense cake.
- Let it Cool Down: Make sure you let the cake cool down before adding the frosting. Otherwise, it’s going to melt the frosting and change its flavor and texture.

My Storage Tips
To store any leftovers that you may have (although I doubt it), wrap the cake in plastic wrap or store it in an airtight container in the fridge. You can keep it there for up to 5-6 days.
While you can store it in the freezer, make sure you do it without the frosting. Cut the cake into individual slices and store them for up to 3 months.

WHY IS THE PROTEIN POWDER THERE?
CAN I USE SOMETHING ELSE OR LEAVE IT OUT?
I use protein powder, to add more protein. You can just swap it for oat flour or almond flour!
