These Birthday Cake Protein Bars are a delicious and fun way to enjoy a sweet treat that’s packed with protein. Made with creamy cashew butter, vanilla protein powder, and festive rainbow sprinkles, these no-bake bars come together quickly and offer a soft, chewy texture perfect for a nutritious snack or post-workout boost.


Ingredients

Scale

Main Ingredients

  • ¾ cup creamy cashew butter (192g) – Smooth and nutty base
  • ¼ cup + 1 tbsp almond milk – Keeps the bars soft and chewy
  • 1 tbsp maple syrup – Adds natural sweetness
  • 2 tsp vanilla extract – Essential for the cake-like flavor
  • ¼ tsp almond extract – Enhances the sweetness
  • 1 cup vanilla protein powder (100g) – Protein-packed base
  • Pinch of sea salt – Enhances flavors
  • 2 tbsp rainbow sprinkles – For a fun, festive touch


Instructions

  1. Prepare the Pan: Line a bread pan with parchment paper and set aside to make removal easy once the bars are set.
  2. Mix Wet Ingredients: In a medium bowl, whisk together the creamy cashew butter, almond milk, maple syrup, vanilla extract, and almond extract until the mixture is smooth and well combined.
  3. Add Dry Ingredients: Stir in the vanilla protein powder and a pinch of sea salt, mixing until a dough forms. If the mixture feels too dry, add more almond milk one teaspoon at a time until it reaches a sticky, moldable consistency.
  4. Fold in Sprinkles: Gently fold the rainbow sprinkles into the dough to evenly distribute the festive colors without melting them.
  5. Shape & Chill: Press the mixture firmly and evenly into the prepared pan, smoothing the top with a spatula or your hands for uniform thickness.
  6. Refrigerate: Place the pan in the refrigerator for 10 to 15 minutes to allow the bars to firm up and hold their shape.
  7. Slice & Serve: Once set, lift the mixture out of the pan using the parchment paper, cut into 6 bars, and enjoy your protein-packed birthday treat.
  8. Store Leftovers: Keep the remaining bars stored in an airtight container in the refrigerator for up to 1 week for freshness.

Notes

  • Use creamy cashew butter for the best texture; chunky nut butters may alter the consistency.
  • If you prefer a sweeter bar, add a little more maple syrup to taste.
  • For a nut-free version, almond milk and cashew butter can be substituted with seed butter and oat milk.
  • The bars are best stored refrigerated to maintain firmness and freshness.
  • Feel free to swap vanilla protein powder with your favorite flavor, but protein content may vary.
