Ingredients
- 432 g (15.25 oz) boxed cake mix (Funfetti cake mix recommended for vibrant cookies)
- 114 g (1/2 cup) unsalted butter, melted
- 2 large eggs, at room temperature
- 170 g (3/4 cup) unsalted butter, at room temperature (for frosting)
- 240 g (2 cups) powdered sugar (confectioners' sugar)
- 5 mL (1 teaspoon) vanilla extract
- 0.6 mL (1/8 teaspoon) fine sea salt
- 30 mL (2 tablespoons) heavy cream
- 40 g (1/4 cup) colorful sprinkles (for garnish)
Instructions
- Preheat your oven to 177 degrees Celsius (350 degrees Fahrenheit). Prepare your baking sheet pans by lining them with either silicone baking mats or parchment paper. This ensures even baking and prevents sticking.
- In a large mixing bowl, combine the cake mix, melted unsalted butter, and room temperature eggs. Stir these ingredients thoroughly with a sturdy spoon or spatula until they are well combined and a cohesive, slightly sticky cookie dough forms. Avoid overmixing, as this can lead to tougher cookies.
- Using a large cookie scoop, approximately 3 tablespoons in size, portion out the cookie dough. Place the scooped dough onto the prepared baking sheet pans, ensuring adequate space between each portion (about 5 cm or 2 inches) to allow for proper spreading during baking. This helps achieve uniformly baked cookies.
- Bake the cookies for 12 to 13 minutes. You'll know they're ready when the edges appear set and lightly golden, and the centers have puffed up slightly. Do not overbake; the cookies will firm up more as they cool. Remove the pans from the oven.
- Allow the baked cookies to cool on the baking sheet for 2 minutes. This brief cooling period helps them set further before transferring. After 2 minutes, carefully transfer the cookies to a wire rack to cool completely. Ensuring they are fully cool before frosting is crucial to prevent the buttercream from melting.
- For the vanilla buttercream, place the room temperature unsalted butter in the bowl of a stand mixer fitted with a paddle attachment, or use a large bowl with an electric hand mixer. Cream the butter on medium-high speed for about 5 minutes until it becomes notably light in color, fluffy, and creamy in texture. This aeration is key for a light frosting.
- Add the powdered sugar, vanilla extract, and salt to the creamed butter. Begin mixing on a low speed to incorporate the dry ingredients without creating a cloud of sugar. Once combined, increase the speed to medium. As needed, pause to scrape down the sides and bottom of the bowl to ensure all ingredients are thoroughly mixed.
- Drizzle in the heavy cream. Once the cream is added, increase the mixer speed to medium-high and whip the frosting for an additional 2 to 3 minutes. This final whipping step makes the frosting incredibly smooth, airy, and creamy, giving it the perfect piping consistency.
- Prepare a piping bag by fitting it with a Wilton 1M piping tip (or a similar star tip for decorative swirls). Fill the piping bag with the prepared vanilla buttercream frosting. Pipe a generous, appealing swirl of frosting onto each completely cooled cookie. Finally, adorn the frosted cookies with a scattering of colorful sprinkles for a festive finish.

Tools You’ll Need
- Large mixing bowl
- Baking sheet pans
- Silicone baking mats or parchment paper
- Large cookie scoop (3 tablespoons)
- Wire cooling rack
- Stand mixer with paddle attachment or electric hand mixer
- Rubber spatula
- Piping bag
- Wilton 1M piping tip (or similar star tip)
Essential Success Tips
- Ensure your eggs are at room temperature. This helps them incorporate more smoothly into the dough, leading to a more consistent cookie texture.
- Do not overmix the cookie dough. Mixing just until combined prevents gluten from overdeveloping, which can make cookies tough.
- Measure your ingredients accurately, especially the butter and sugar for the frosting. Precision is key for the ideal frosting consistency.
- Allow cookies to cool completely before frosting. Applying buttercream to warm cookies will cause it to melt and slide off.
- Use good quality unsalted butter for both the cookies and frosting, as it significantly impacts flavor and texture.
Professional Cooking Secrets
- For an extra layer of flavor and moisture in the cookies, try adding 5 mL (1 teaspoon) of vanilla extract or almond extract to the cookie dough itself, even if not listed, for a gourmet touch.
- When making buttercream, whip the butter for a full 5 minutes before adding other ingredients to incorporate maximum air, resulting in a lighter, fluffier frosting that pipes beautifully.
- To achieve perfectly uniform cookies, weigh your scooped dough portions. For a 3-tablespoon scoop, each cookie dough ball should be approximately 45-50 grams (1.6-1.8 ounces).

Notes
- Storage: Store frosted cookies in an airtight container at room temperature for up to 3 days, or in the refrigerator for up to 5 days. Bring to room temperature before serving for best texture.
- Freezing: Unfrosted cookies can be frozen for up to 3 months. Thaw at room temperature before frosting. Frosted cookies can also be frozen, best to freeze solid on a tray first, then transfer to an airtight container.
- Flavor Variations: Experiment with different cake mix flavors, such as chocolate, lemon, or red velvet, and pair them with complementary frosting flavors.
Frequently Asked Questions
Can I use any brand of cake mix for these cookies?
Yes, you can use almost any brand of standard 432 g (15.25 oz) boxed cake mix. The key is to stick to the specified weight. Different flavors will yield different cookie experiences, making it fun to experiment!
My cookies are spreading too much. What went wrong?
Excessive spreading can be due to several factors: your butter might have been too warm (even melted butter should not be scorching hot), your eggs might not have been at room temperature, or your oven temperature might be inaccurate. Ensure precise measurements and proper ingredient temperatures.
How can I make the buttercream less sweet?
To reduce sweetness, you can try adding a pinch more salt (a flavor enhancer) or a few drops of lemon juice or cream of tartar to cut through the sugar. Ensure you're using unsalted butter to control the overall sodium content.
