Introduction

Birthday Cake Protein Balls are a fun and nutritious snack that tastes like a celebration in every bite. Packed with creamy cashew butter, oats, and protein powder, they make for an easy, no-bake treat perfect for a quick energy boost or a guilt-free dessert.

A stack of seven round peanut butter balls with a light brown, slightly textured base are on a white ceramic plate with a speckled, rustic design. Each ball is partially covered on the top with colorful rainbow sprinkles in pastel shades including pink, orange, yellow, green, blue, and white, giving a festive look. The balls are piled in layers, four balls at the bottom, two in the middle, and one balanced on top. There are scattered sprinkles on the white marbled surface around the plate. In the background, slightly out of focus, a white bowl contains a creamy peanut butter mixture with a spoon inside. A soft peach-colored cloth adds warmth to the scene. photo taken with an iphone --ar 4:5 --v 7

Ingredients

1 cup natural creamy cashew butter
½ cup vanilla protein powder

¾ cup rolled oats
2 teaspoons vanilla extract

¼ cup honey
3 tablespoons sprinkles (plus more for rolling)

¾ teaspoon salt

Instructions

Step 1: Add all of the ingredients to a mixing bowl, then use a rubber spatula to mix it together until a thick batter forms.
Step 2: Line a baking sheet with wax paper. Use a mini cookie scoop to drop balls of batter onto the baking sheet.

Step 3: Roll each ball in your hands to smooth out the edges, then dip the top into a bowl of sprinkles and press down lightly.
Step 4: Place the energy bite back onto the baking sheet sprinkle side up. Repeat the process for the remaining energy bites.
Step 5: Refrigerate the energy bites until firm, then transfer them to an airtight container. Store in the refrigerator or freezer.

Tips & Variations

Use almond or peanut butter as a substitute for cashew butter for a different flavor profile.
Choose your favorite flavor of protein powder to customize the taste.
Add a pinch of cinnamon or nutmeg for extra warmth and depth.

Roll the balls in crushed nuts instead of sprinkles for a crunchy coating.

Storage

Store the protein balls in an airtight container in the refrigerator for up to one week or in the freezer for up to one month. To enjoy, allow frozen balls to thaw in the fridge for 30 minutes before eating. No reheating is necessary.

How to Serve

A clear glass dish holds fifteen round, smooth brown treats topped with a thick layer of colorful sprinkles in pink, green, white, blue, orange, and yellow. The treats are tightly packed in three rows of five on a white marbled surface. Around the dish, scattered oat flakes and a glass bowl filled with oats and a wooden spoon are visible above, while a peach-colored textured cloth lies beneath and to the right, near a small white dish filled with more multicolored sprinkles.

Notes

Use natural creamy cashew butter without added sugars or oils for best texture and flavor.
The salt enhances the sweetness and balances flavors – do not omit.
You can substitute honey with maple syrup for a vegan option.

Sprinkles add festive color but can be omitted or replaced with mini chocolate chips for variation.
If the mixture feels too dry, add a little more cashew butter or a splash of milk to achieve the right consistency.
