Brightened with colorful sprinkles and coated in creamy white chocolate, they offer a fun twist on traditional protein bars. Ready in just 20 minutes, they make an ideal homemade energy pick-me-up.

Ingredients
- ½ cup vanilla protein powder (packed)
- ¼ cup coconut flour
- Pinch of baking soda (optional)
- 2 tbsp confetti sprinkles
- 3 tbsp unsweetened applesauce
- 1 tbsp almond milk (or water)
- 1 tbsp butter-flavored coconut oil, melted
- ¾ cup white chocolate chips (for coating)
- Optional: 1 tsp coconut oil (for thinning chocolate)
Instructions
- Step 1: In a medium bowl, whisk together the vanilla protein powder, coconut flour, baking soda if using, and confetti sprinkles until evenly combined.
- Step 2: Stir in the unsweetened applesauce, almond milk (or water), and melted butter-flavored coconut oil until a dough forms.
- Step 3: Adjust the dough consistency as needed—if too soft, add more coconut flour one teaspoon at a time; if too dry, add more almond milk or water one teaspoon at a time.
- Step 4: Shape the dough into a rectangular mound, then wrap it in plastic wrap or place it in an airtight container. Chill in the refrigerator for at least 30 minutes to firm up.
- Step 5: Once firm, slice the chilled dough into 5 equal bars.
- Step 6: Melt the white chocolate chips in the microwave using 20-second intervals, stirring between each until smooth. Add 1 teaspoon of coconut oil if a thinner, smoother coating is desired.
- Step 7: Dip each bar into the melted white chocolate or drizzle the chocolate over the top, then place the bars on parchment paper to set.
- Step 8: Let the chocolate coating harden completely before serving for the best texture and taste.
Tips & Variations
- For a dairy-free version, use non-dairy white chocolate chips and ensure your protein powder is plant-based.
- Add a teaspoon of vanilla extract to the wet ingredients for extra flavor depth.
- Swap confetti sprinkles for mini chocolate chips or chopped nuts for different textures.
- If you prefer a softer bar, reduce chill time slightly or add a bit more applesauce.
Storage
Store the bars in an airtight container in the refrigerator for up to 5 days. To enjoy, let them sit at room temperature for a few minutes before eating. These bars also freeze well—wrap individually and store in a freezer-safe container for up to 2 months. Thaw in the fridge overnight before serving.

FAQs
Can I use a different protein powder?
Yes, you can substitute any vanilla or unflavored protein powder, but be aware that the texture and flavor might vary slightly depending on the brand and type.
What can I use instead of coconut flour?
Coconut flour is absorbent and unique, so substitutions can be tricky. Almond flour can be tried, but you may need to adjust liquid amounts. It’s best to use coconut flour for the intended texture.

Instructions
- Mix Dry Ingredients: In a medium bowl, whisk together vanilla protein powder, coconut flour, optional baking soda, and confetti sprinkles until well combined.
- Add Wet Ingredients: Stir in the applesauce, almond milk (or water), and melted butter-flavored coconut oil until a cohesive dough forms.
