How to Make Confetti Dot Sheet Cake
-
Preheat the oven: Start by preheating your oven to 325°F. This helps the cake to bake evenly. Don’t forget to grease and line a light-colored metal 9×13 cake pan with parchment paper for easy removal later!
-
Cream the butter and sugar: In the bowl of your stand mixer fitted with the paddle attachment, beat the 1 cup of salted butter and 1 ¾ cups of granulated sugar together on medium-high speed for 3-5 minutes. You’re aiming for that pale and fluffy texture—just imagine how rich it’s going to taste!
-
Add the eggs and extracts: Next, add 4 eggs one at a time, ensuring each one is mixed in well after it’s added. Then, introduce 1 tablespoon of vanilla extract and ¼ teaspoon of almond extract for a flavor burst!
-
Mix the dry and wet ingredients: In a separate bowl, whisk together 3 cups of all-purpose flour, 1 tablespoon of cornstarch, 2 teaspoons of baking powder, and ½ teaspoon of kosher salt. In another bowl, whisk together 1 cup of whole milk, ⅓ cup of full-fat sour cream, and ¼ cup of vegetable oil.
-
Combine them gently: With the mixer on low speed, alternate adding the dry ingredients and the wet ingredients, starting and finishing with the dry mix. Be careful not to overmix! Just combine until it’s smooth, then fold in the ½ cup of rainbow sprinkles for that festive touch!
-
Bake the cake: Spread the batter evenly into your prepared pan. Bake for 35-40 minutes, checking for doneness with a toothpick. It should come out clean or with a few moist crumbs. Once baked, let the cake cool completely in the pan.
-
Make the frosting: To create your luscious frosting, beat 1 cup of salted butter until it’s smooth and creamy (about 2-3 minutes). Gradually add in 4 cups of powdered sugar, one cup at a time, combining on low speed. Mix in 2 teaspoons of vanilla extract, ½ teaspoon of salt, and 3-4 tablespoons of heavy cream. Increase the speed to medium-high and beat for 2-3 minutes until it’s fluffy and perfectly smooth!
-
Frost and decorate: Once the cake has cooled, generously spread the frosting over the top while it’s still in the pan. Add a sprinkle of colorful, fun 2 cups of rainbow nonpareil sprinkles right away, pressing gently into the frosting to help them stick. Refrigerate the cake for 20-30 minutes before slicing to make it easier to serve!
Optional: Add a sprinkle of extra rainbow sprinkles on each slice for whimsy!

Tips for the Best Confetti Dot Sheet Cake
- Perfect Butter Temperature: Always use room temperature butter for a fluffy batter. Cold butter won’t cream well with sugar, resulting in a denser cake.
- Avoid Overmixing: When combining the dry and wet ingredients, mix just until combined. Overmixing can lead to a tough cake rather than the desired tender crumb.
- Fresh Ingredients: Ensure your baking powder is fresh for optimal rise. Expired baking powder can lead to a flat cake.
- Cooling Time: Allow the cake to cool completely before frosting. This prevents the frosting from melting and sliding off, ensuring a beautiful finish.
- Sprinkle Technique: Press the rainbow nonpareil sprinkles into the frosting right after spreading to enhance adherence. This keeps them vibrant and prevents color bleeding.
How to Store and Freeze Confetti Dot Sheet Cake
Fridge: Store the cake in an airtight container in the refrigerator for up to 3 days. This keeps the frosting fresh and the cake moist.
Freezer: To freeze the cake, wrap it tightly in plastic wrap and then aluminum foil. It can be stored in the freezer for up to 2 months.
Reheating: When ready to enjoy, thaw overnight in the fridge. For a warm treat, gently reheat individual slices in the microwave for about 10-15 seconds.
Serving Tip: Allow the cake to come to room temperature after freezing to restore its lovely fluffy texture before serving!

Confetti Dot Sheet Cake Recipe FAQs
What should I look for when selecting rainbow sprinkles?
When choosing rainbow sprinkles for your Confetti Dot Sheet Cake, go for ones that are vibrant and free from any broken pieces.

This will ensure that your cake looks as cheerful and festive as it tastes!
How long can I store my Confetti Dot Sheet Cake in the fridge?
Absolutely! You can keep your Confetti Dot Sheet Cake in an airtight container in the refrigerator for up to 3 days. This helps to maintain the cake’s moistness and keeps the frosting from becoming too soft. Just remember to slice the cake only when you’re ready to serve for the freshest taste!

What if my cake sinks in the middle?
If your Confetti Dot Sheet Cake sinks in the middle, it could be due to underbaking or overmixing the batter. Always check for doneness using a toothpick; a few moist crumbs are perfect. If you suspect it might not be baked enough, bake it a few minutes longer, checking frequently. Avoid mixing the batter too much after adding flour to keep the texture light and airy.
Are there any allergy considerations for this cake?
Yes! This Confetti Dot Sheet Cake contains common allergens, such as eggs and dairy. If you’re baking for someone with allergies, consider using egg replacements like flax eggs or applesauce and non-dairy milk and butter substitutes.

Can I make this cake in advance for an event?
Definitely! You can bake the cake up to a day ahead of your event. Once it has cooled completely, cover it and store it (unfrosted) at room temperature or in the fridge for up to a day.
