Ingredients: What You’ll Need

Let’s get that shopping list ready. Here’s everything you need to make about 24 cookies:

• 1 cup (2 sticks) unsalted butter (room temperature, for maximum creaminess)
• 1 ¼ cup granulated sugar
• 1 large egg
• 2 tsp vanilla extract (use high-quality vanilla for the best flavor)
• 1 ½ cups all-purpose flour
• ½ cup yellow cake mix (you can use any brand, but Betty Crocker or Duncan Hines work well)
• 1 tsp baking powder
• ¼ tsp salt
• ½ cup rainbow sprinkles (not nonpareils; we’re talking the classic jimmies)
• ½ cup white chocolate chips (optional, but they add a creamy sweetness)

Preparation Steps: Barney-Style Breakdown

Before we get baking, let’s set everything up for success:

1. Prep the oven: Preheat it to 350°F (175°C) and line two baking sheets with parchment paper.

2. Butter game strong: In a large mixing bowl, cream together the butter and sugar until light and fluffy. You’re looking for a pale, almost whipped consistency—this ensures a soft cookie.

3. Add the egg and vanilla: Once the butter and sugar are creamed, crack in the egg and pour in the vanilla extract. Beat until smooth and well combined.

4. Dry ingredients come to play: In a separate bowl, whisk together the flour, cake mix, baking powder, and salt. Slowly add this to the wet mixture, stirring until combined into a dough.

5. Mix in the fun: Gently fold in your rainbow sprinkles and, if you're feeling it, those white chocolate chips.

6. Chill time: Stick your dough in the fridge for about 30 minutes. Chilling helps the cookies hold their shape when baking, and intensifies the flavors.

Baking Instructions: Time to Shine

1. Scoop and shape: After the dough is chilled, use a cookie scoop or tablespoon to drop balls of dough onto the prepared baking sheets. Space them about 2 inches apart, as these cookies will spread.

2. Into the oven: Bake the cookies for 10-12 minutes, or until the edges are just slightly golden. The centers should still look soft—that’s the secret to a chewy cookie! Avoid over-baking.

3. Cool and enjoy: Let the cookies cool on the baking sheet for a few minutes before transferring them to a wire rack to cool completely. (Or sneak one while they’re still warm, because who can resist?)

Serving Suggestions: Let’s Make These Pop

Birthday Cake Cookies are a party on their own, but here are a few fun serving ideas:

• Milk and cookies classic: Serve these with a tall glass of cold milk for ultimate nostalgia.
• Ice cream sandwich: Take two cookies and sandwich a scoop of vanilla ice cream in between for an extra indulgent treat.
• Frosting drizzle: Want to go over the top? Drizzle a little birthday cake frosting on top and add extra sprinkles.

Additional Tips: How to Level Up the Recipe

• Flavor boosters: Want to take it up a notch? Swap the vanilla extract for almond extract to give the cookies a more sophisticated flavor.
• Dietary tweaks: If you need a gluten-free option, use gluten-free flour and make sure your cake mix is also gluten-free.
• Sprinkle secrets: Avoid using nonpareil sprinkles (the tiny round ones) as they can bleed color and mess with the texture of your dough. Stick to jimmies for the best results.
