directions

Preheat the oven
Preheat your oven to 325°F (163°C) and line a 12-cup muffin tin with cupcake liners or baking cups.
Mix dry ingredients
In a large bowl, combine the vanilla protein powder, all-purpose flour, coconut flour, and baking powder. Break up any clumps, especially from the coconut flour.
Add wet ingredients
Gradually stir in the almond milk, light butter, Greek yogurt, egg, and vanilla extract. Mix until smooth and evenly incorporated.
Fold in sprinkles
Gently fold in the confetti sprinkles, if using.
Fill liners
Divide the batter evenly among the cupcake liners. Each should be about ¾ full.
Bake
Bake the cupcakes for 20–22 minutes, or until a toothpick inserted in the center comes out clean. Avoid overbaking, as protein-based baked goods can become dry.
Cool
Remove cupcakes from the tin and allow them to cool completely on a wire rack before frosting.
Prepare frosting
In a bowl, mix together the cream cheese, Greek yogurt, protein powder, and food coloring (if using) until smooth.
Frost cupcakes
Pipe or spread the frosting onto the cooled cupcakes. Top with additional sprinkles if desired. For storage, keep the frosting separate until ready to eat.

FAQs

1. Can I use a different protein powder?

Yes, but the texture may vary. Whey, casein, or plant-based protein powders all behave slightly differently in baking. Adjust the liquid as needed if your batter is too thick or thin.

2. Why did my cupcakes turn out dry?

Protein baked goods dry out easily if overcooked. Be sure to bake just until a toothpick comes out clean, and avoid extended baking times.

3. Can I use only one type of flour?

Combining all-purpose and coconut flour helps balance moisture and texture. Using just one may require adjusting the liquid and fat content.

4. Are these cupcakes gluten-free?

No, the recipe contains all-purpose flour. You can substitute a 1:1 gluten-free baking blend, but results may vary slightly.

5. Can I omit the frosting?

Yes. The cupcakes are still flavorful on their own, and skipping the frosting reduces calories and prep time.

6. How much protein is in each cupcake?

This will vary based on the brand of protein powder used. On average, each cupcake contains around 8–10 grams of protein.

7. Can I double the recipe?

Yes. Simply double all ingredients and bake in two batches or use two muffin tins if available.

8. What’s the purpose of the coconut flour?

Coconut flour adds fiber and structure, but it also absorbs a lot of liquid. That’s why you only need a small amount.

9. Can I add sweetener to the batter?

If your protein powder isn’t sweet enough, you can add a little granulated or liquid sweetener to taste.

10. Do I have to use food coloring?

Not at all. The food coloring is purely for appearance. You can omit it or use a natural color alternative.

These birthday cake protein cupcakes are a smart, fun twist on classic cupcakes, offering both flavor and function.
