No-Bake Birthday Cake Energy Balls – Ready in 15 Minutes

When I was growing up, birthdays in our kitchen always meant sprinkles everywhere and my mom humming while she mixed something sweet on the counter. I remember standing on a chair, stirring vanilla and oats together, sneaking a taste before anything had time to set. This takes me right back to those colorful afternoons, no oven, just a bowl, a spoon, and a little patience while everything chilled. My mom always said sprinkles make anything feel special. Let me tell you, these Birthday Cake Energy Balls still bring that same joy.

Equipment

  • Microwave-safe bowl or small saucepan
  • Wooden spoon or spatula
  • Cookie Scoop
  • Parchment Paper
  • baking sheets
  • Measuring tools

Ingredients
  

  • 2 cups old-fashioned rolled oats
  • ½ cup creamy cashew butter or almond butter
  • cup honey
  • ¼ cup vanilla protein powder optional for structure
  • 2 tablespoons ground flaxseed
  • 1 teaspoon vanilla extract
  • ¼ teaspoon almond extract optional, for classic cake flavor
  • Pinch of salt
  • 3 tablespoons rainbow sprinkles plus extra for rolling
  • 1 –2 tablespoons milk as needed for texture

Instructions
 

  • In a microwave-safe bowl or small saucepan over low heat, gently warm the nut butter and honey until smooth and easy to stir (about 30–45 seconds in microwave or 2–3 minutes on low heat). Do not boil.
  • Remove from heat and stir in vanilla extract, almond extract (if using), and salt.
  • In a large mixing bowl, combine oats, protein powder (if using), and flaxseed.
  • Pour the warm mixture over the dry ingredients and stir until fully combined.
  • If mixture feels dry, add 1 tablespoon milk at a time until it holds together when pressed.
  • Fold in rainbow sprinkles gently to prevent color bleeding.
  • Scoop tablespoon-sized portions and roll into balls. Roll lightly in extra sprinkles if desired.
  • Place on parchment-lined baking sheets and refrigerate for at least 30 minutes until firm and set.

Notes

Storage: Store in an airtight container in the refrigerator for up to 1 week.
Freezing: Freeze up to 2 months. Thaw 5–10 minutes before serving.
Humidity Effects: In humid climates, increase oats by 1–2 tablespoons to prevent soft texture.
Troubleshooting:
  • Too crumbly? Add 1 teaspoon honey or milk at a time.
  • Too sticky? Add oats or chill mixture before rolling.
  • Sprinkles bleeding? Fold in at the very end and avoid overmixing.
