Then comes baking. I bake them just until the edges look set but the centers still seem slightly soft. Every oven is different, but for me, that sweet spot is usually around 9–11 minutes. When they come out of the oven, I let them rest on the baking sheet for a couple of minutes before transferring them to a cooling rack. That cooling moment firms up the soft centers into the perfect, chewy cookie.
Pro Tips for Best Results
I’ve tested this recipe more times than I can count, and one thing I’ve learned is to chill the dough if your kitchen is warm. Even just 20 minutes in the fridge helps prevent the cookies from spreading too much. Another tip I discovered: don’t substitute margarine for butter. I tried it once when I ran out, and the cookies turned out flat, greasy, and lacking flavor. Real butter is essential.
I’ve also experimented with different sprinkle types. Jimmies are the best choice for inside the dough because they hold their shape beautifully. If you want a crunchy outside coating, you can roll the dough balls in nonpareils, but avoid mixing them inside the dough—they bleed instantly. Another trick: if you want extra-thick cookies, add an additional ounce of cream cheese.
Lastly, if you want picture-perfect cookies, use a cookie scoop. The uniform size helps everything bake evenly. I also gently press the tops of the dough balls before baking so they spread evenly instead of rising too tall.
Common Mistakes to Avoid
I made a big mistake the first time I made these: I used too many sprinkles inside the dough. Believe it or not, you can overdo it. If you add too many, they can cause the dough to fall apart because sprinkles don’t behave like flour. Another mistake is overbaking—these cookies look almost underbaked when they’re done, but they set beautifully as they cool. If you wait until they look fully baked, they’ll turn dry.
Another mishap I’ve experienced is using the wrong type of cream cheese. You need the block-style cream cheese, not the whipped kind from a tub. The tub version is too soft and watery, and it makes the dough sticky and impossible to shape. One time I tried to make them without chilling the dough on a hot day, and they spread into pancake shapes—so don’t skip chilling if your kitchen feels warm.
Also, be careful while folding in sprinkles. Overmixing will streak the dough and muddy the colors. Gentle folding is absolutely the way to go.

I love serving these Rainbow Sprinkle Cookies with a big glass of cold milk—it’s such a nostalgic combination that brings me right back to childhood. I also like arranging them on a colorful platter for parties; their bright sprinkles make them instantly eye-catching.
