Ingredients

(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)

All-purpose flour
Baking powder
Baking soda
Salt
Unsalted butter, softened
Granulated sugar
Egg
Vanilla extract
Almond extract (optional)
Rainbow sprinkles (jimmies or confetti-style)

Directions

I preheat the oven to 350°F (175°C) and line a round baking pan or cake pan with parchment paper.
In one bowl, I whisk together the flour, baking powder, baking soda, and salt.
In another bowl, I cream the butter and sugar together until light and fluffy.
I beat in the egg, vanilla, and almond extract (if using).
I gradually add the dry ingredients and mix until just combined.
I fold in the rainbow sprinkles, being careful not to overmix.
I press the dough evenly into the prepared pan and add a few extra sprinkles on top.
I bake for 18–22 minutes, or until the edges are set and the center is slightly golden but still soft.
I let it cool before slicing into wedges or squares.

Variations

I add white chocolate chips for extra sweetness.
I change the sprinkle colors to match holidays or events.
I top it with frosting or a glaze for a birthday cake effect.
I use gluten-free flour to make it gluten-free.

storage/reheating

I store leftovers in an airtight container at room temperature for up to 4 days. To keep it soft, I place a piece of bread in the container. If I want to reheat, I warm slices in the microwave for a few seconds to bring back the fresh-baked feel. Giant Funfetti Sugar Cookie

FAQs

Can I use a different pan?

Yes, I use a square or rectangular pan if I prefer bars instead of a round cookie. Just adjust the baking time slightly if it’s thicker.

What type of sprinkles work best?

I use jimmies or confetti sprinkles—they hold their shape and color best during baking. I avoid nonpareils, which can bleed into the dough.

Can I make the dough ahead of time?

Yes, I prepare the dough and store it in the fridge for up to 2 days. I press it into the pan just before baking.

How do I know when it’s done?

I check that the edges are golden and the center looks set but soft. It continues to cook a bit as it cools.

Can I freeze it?

Yes! I freeze the whole baked cookie or individual slices. I let it thaw at room temperature or warm it slightly before serving.

Conclusion

The Giant Funfetti Sugar Cookie is a colorful, crowd-pleasing dessert that’s as easy as it is fun. I love how cheerful it looks and how simple it is to make—no scooping, no fuss, just one big cookie that’s ready to party.
