What Is Funfetti?

Funfetti is just vanilla cake with rainbow sprinkles added to the batter before baking. It doesn’t really taste any different from vanilla cake but the pop of color from the sprinkles makes it look so fun! In this case, our funfetti is a vanilla sugar cookie with rainbow sprinkles.

Which Sprinkles Are Best For Funfetti Cookies?

When making any type of funfetti dessert, whether it be cake, cookies, etc., you should always use jimmies sprinkles! You never want to use nonpareils because they tend to bleed into the dough. Confetti quins will also work if that’s all you have on hand.

Ingredient Breakdown

All-purpose flour – this gives the cookies structure.

Baking soda & baking powder – both leaveners are needed to help the cookies rise.

Butter – provides flavor and structure. I always recommend using unsalted butter but salted butter works if that’s all you have on hand, just be sure to omit the 1/4 teaspoon of salt later on. Do not use cold or melted butter.

Granulated sugar – provides sweetness and texture.

Egg – binds the ingredients and provides structure.

Vanilla extract and salt – enhances flavor. Always use pure vanilla extract instead of imitation for best flavor.

Sprinkles – make sure that you use jimmies and not nonpareils because nonpareils tend to bleed into the dough. Confetti quins will also work if that’s all you have on hand.

How To Make Funfetti Sandwich Cookies

1. Make the Funfetti Cookie Dough: In a small bowl combine the all-purpose flour, baking powder, baking soda and salt.

2. Use a stand mixer fitted with the paddle attachment to cream the softened butter and granulated sugar until light and fluffy.

3. Add the egg and vanilla extract then mix until just combined. Scrape the sides of the bowl.

4. Add the dry ingredients all at once and mix on low speed until almost combined (there should still be streaks of flour). Then add the sprinkles and mix on low speed until just combined. Do not over mix the dough because it will make the cookies tough and the sprinkles will bleed.

5. Using a 1 tablespoon cookie scoop, scoop dough onto lined baking sheets (be sure to adjust the baking time if your cookies are smaller/larger). If desired, you can press extra sprinkles onto the tops of each cookie dough ball so that they bake up extra pretty!

6. Bake funfetti cookies at 350°F for 8 minutes then cool on the baking sheet. The cookies will still look slightly raw when they come out but will continue to bake as they cool.

7. Make the Vanilla Buttercream: Using a hand mixer or a stand mixer fitted with the paddle attachment, cream the butter until light and fluffy. Add confectioners’ sugar and mix on low until combined. Then add the vanilla extract and heavy cream or milk and beat until fluffy. Add salt to taste.

8. Pipe or spread a layer of vanilla buttercream onto half of the funfetti cookies then top with the remaining cookies. Store Funfetti Sandwich Cookies in an airtight container for up to 4 days at room temperature or up to a week in the fridge.

Pro Tips For Funfetti Sandwich Cookies

• Weigh your ingredients using a kitchen scale! Measuring ingredients by volume is not accurate.
• Don’t over mix the dough! There should still be streaks of flour in the dough when you add the sprinkles. Over mixing = more gluten development which means tough cookies. We don’t want any tough cookies here! Over mixing can also cause the sprinkles to bleed into the dough.
• Bake one tray at a time on the middle oven rack. This ensures that there is even heat circulation.
• Don’t over bake them! They will still look a little raw when they come out of the oven but will continue to bake as they cool on the baking sheet. This is the secret to crisp edges and chewy centers.
• Use jimmies sprinkles and not nonpareils because nonpareils tend to bleed into the dough. Confetti quins will also work if that’s all you have on hand.
• Try pressing some extra sprinkles onto the tops of each cookie dough ball so that they bake up extra pretty!
• Try adding a little bit of almond extract to the dough for almond flavored funfetti cookies!
