These soft, bite-sized treats combine the nostalgic flavor of birthday cake batter with the nutritional benefits of protein. The dough blends vanilla protein powder with oat flour and coconut flour, sweetened naturally with pure maple syrup and enriched with creamy almond butter. Rainbow sprinkles are folded throughout for authentic celebration vibes.
The mixture comes together in minutes without any baking required—simply combine, roll into one-inch balls, and chill until set. Each protein-packed bite delivers vanilla sweetness with satisfying texture from the oats and protein powder. Roll the exterior in additional sprinkles for extra festive presentation.
Perfect for meal prep snacks, post-workout fuel, or healthier dessert alternatives. The dough holds beautifully in the refrigerator for a week or freezes for months, making batch preparation effortless. Cashew butter creates an even milder cake batter profile, while dairy-free milk options keep these accommodating for various dietary needs.
My roommate walked in on me standing at the counter with rainbow sprinkles stuck to my elbows at 11 PM on a Tuesday.
I originally made these for meal prep but ended up bringing them to a friends birthday instead of an actual cake.

Recipe FAQs
- → Can I use different nut butters?
-
Absolutely. Cashew butter creates a milder, more traditional cake batter flavor. Peanut butter adds a robust nutty note. Sunflower seed butter works for nut-free households, though the flavor profile shifts slightly.
- → What if the dough feels too dry or sticky?
-
Add milk one tablespoon at a time until the dough holds together without crumbling. If too sticky, incorporate another tablespoon of coconut flour or protein powder. The consistency should resemble firm cookie dough.
- → Do these need to be refrigerated?
-
Yes. Chilling for at least 30 minutes helps them firm up and hold their shape. Store refrigerated in an airtight container for up to one week, or freeze for two months. Let frozen ones thaw 5-10 minutes before eating.
- → Can I make these vegan?
-
Certainly. Choose a plant-based protein powder and verify your sprinkles are vegan-friendly (many contain confectioner's glaze or dairy). Use dairy-free milk and maple syrup is already plant-based.
- → What protein powder works best?
-
Vanilla whey or casein create the softest texture. Plant-based blends work but may absorb more liquid, requiring additional milk. Avoid unflavored powder—the vanilla essence is crucial for authentic cake batter flavor.
- → Can I reduce the sweetness?
-
Decrease maple syrup to 2 tablespoons or substitute with liquid stevia to taste. The protein powder and sprinkles already provide sweetness, so you may not need the full amount depending on your preference.
