Ingredients You’ll Need
Every ingredient brings something special—flavor, texture, or that classic “birthday cake” vibe.
Main Ingredients
- 1 cup vanilla protein powder – choose whey or plant-based for your preference
- 1 cup oat flour – adds texture; use almond flour for grain-free option
- ½ cup cashew or almond butter – creamy binder with mild flavor
- ¼ cup honey or maple syrup – natural sweetness (maple for vegan)
- 1 tsp vanilla extract – enhances the cake batter taste
- ½ tsp almond extract – adds that nostalgic bakery aroma
- ½ cup rainbow sprinkles – colorful, fun crunch
- 1 pinch salt – balances the sweetness
- 3–4 tbsp milk of choice – adjust for perfect dough consistency
Optional Add-Ons or Substitutes
- Add a scoop of collagen powder for extra protein
- Use coconut milk for a richer taste
- Stir in white chocolate chips for indulgence
- Replace almond extract with butter extract for extra “cake” flavor
- Roll in extra sprinkles for a colorful finish
- Add crushed freeze-dried strawberries for fruity flavor
Step-By-Step Instructions
Making these protein bites is quick, simple, and foolproof.
- Combine dry ingredients. In a large bowl, mix protein powder, oat flour, and salt. (This helps prevent clumps later.)
- Add wet ingredients. Stir in nut butter, honey, vanilla, and almond extract until crumbly. (It’ll look dry before it comes together—don’t worry.)
- Add milk. Slowly pour in milk, 1 tablespoon at a time, until a dough forms. (You want soft, not sticky.)
- Mix in sprinkles. Gently fold in the sprinkles with a spatula. (Save a few for rolling on the outside if you like color.)
- Shape the balls. Roll into 1-inch balls and place on parchment paper. (Use slightly damp hands for easier rolling.)
- Chill and store. Refrigerate for 20 minutes to firm up before serving.
Quick reminders:
- Adjust milk to control texture.
- Use a cookie scoop for even sizes.
- Store in fridge for the best chewy bite.
- Freeze extras for up to 3 months.
Expert Tips For Success
Small tweaks can make your protein balls bakery-worthy.
- Use a high-quality protein powder you enjoy—the flavor matters.
- If the mixture feels dry, add extra nut butter instead of milk.
- For color that doesn’t bleed, use naturally dyed sprinkles.
- Chill dough before rolling for easier handling.
- Store in airtight containers to prevent drying out.
- Add a dash of cinnamon for warmth and complexity.
- Coat in shredded coconut for a fun texture twist.
They pair perfectly with my Vanilla Chai Shortbread Cookies for a cozy, dessert-inspired snack platter.

Storing And Reheating
Though these are no-bake, proper storage keeps them perfect for days.
How To Store It
- Store in an airtight container in the fridge for up to 1 week
- Freeze for up to 3 months in zip bags
- Place parchment between layers to avoid sticking
- Keep at room temp for up to 2 days for soft texture
- Label with flavor or date for easy access
How To Reheat It
- No reheating needed, but if frozen, let thaw at room temperature for 10–15 minutes
- For a gooey texture, microwave for 5 seconds before eating
- Avoid overheating—it can melt the sprinkles or dry the dough
- Add a drizzle of honey if they start to dry out
They keep beautifully, much like my Sweetened Condensed Milk Snowballs, which stay chewy and flavorful even after freezing.
