That creamy, sprinkle-loaded cake batter looks incredible! To hit those stellar macros (365 Calories and 47g of Protein), the secret is using a blend of thick Greek yogurt and a high-quality protein powder (preferably a whey-casein blend, which absorbs liquid much better than pure whey to give you that thick, spoonable "batter" texture).
Here is how you can recreate this exact high-protein, low-carb treat at home:
High-Protein Birthday Cake Batter
Prep time: 5 minutes | Yield: 1 serving
Ingredients
-
170g (approx. 3/4 cup) Nonfat Greek yogurt (Fage 0% works best for thickness)
-
35g (approx. 1.2 scoops) Vanilla protein powder (a Whey/Casein blend like PEScience yields the thickest batter texture)
-
10g (approx. 1 tbsp) Coconut flour (this absorbs moisture and gives it a cake-like flour texture)
-
1/2 tsp Cake batter extract (or sub with 1/4 tsp vanilla extract + 1/4 tsp almond extract)
-
1–2 tbsp Granulated or powdered zero-calorie sweetener (like erythritol or monk fruit, adjusted to taste)
-
1–2 tbsp Unsweetened almond milk (only if needed to help it blend)
-
7g (approx. 1/2 tbsp) Rainbow sprinkles
-
10g (approx. 1 tbsp) Sugar-free white chocolate chips
Instructions
-
Combine the Base: In a medium bowl, add the Greek yogurt, protein powder, coconut flour, sweetener, and cake batter extract.
-
Mix & Adjust: Stir vigorously with a spoon or small spatula until completely smooth. If the mixture is too dry or chalky (depending on your brand of protein powder), add a tiny splash (1 tablespoon) of almond milk and stir again. It should be thick, creamy, and hold its shape on a spoon.
-
Fold in the Fun: Gently fold in the rainbow sprinkles and sugar-free white chocolate chips, saving a few to press on top for that perfect Instagram-ready look.
-
Chill (Optional but recommended): Pop it in the freezer for 10–15 minutes before eating. It thickens up even more and mimics actual cold cake batter beautifully!
💡 Pro-Tips for the Perfect Texture
-
The Protein Powder Matters: Pure whey protein tend to get sticky, runny, or rubbery when mixed with yogurt. Casein or a whey-casein blend absorbs the liquid and expands, creating a true "cookie dough/cake batter" density.
-
Want it warmer? If you prefer a warm cake-like texture, you can microwave this mixture in a mug for about 30 to 45 seconds. It will puff up into a quick, high-protein mug cake!
