Perfect for birthdays, potlucks, or “just because” moments, this funfetti-inspired sheet cake is soft, rich, and generously topped with sweet vanilla frosting and, of course, more sprinkles. It’s easy to make, feeds a crowd, and delivers that nostalgic taste we all secretly crave.

In this guide, you’ll learn how to master the ultimate Sprinkle Sheet Cake with tips on getting the fluffiest crumb, the smoothest frosting, and the brightest, non-bleeding sprinkles. Whether you’re baking for kids or just indulging your inner child, this recipe is a guaranteed mood booster.

🎂 What Is a Sprinkle Sheet Cake?

A Sprinkle Sheet Cake is the dessert equivalent of confetti—bright, festive, and made to celebrate. It’s a soft, buttery vanilla cake baked in a rectangular sheet pan, generously mixed with colorful sprinkles that burst into every bite. Think of it as the no-fuss, crowd-pleasing cousin of the classic layer cake—big on flavor, easy to serve, and perfect for any occasion.

You might also hear this referred to as a Funfetti sheet cake, a term popularized by cake mixes, but this homemade Sprinkle Sheet Cake goes beyond the box. It offers a richer flavor, fluffier texture, and complete control over the ingredients—like choosing the best rainbow sprinkles that won’t bleed or melt.

Unlike layered cakes that demand precision, crumb coats, and multiple pans, the Sprinkle Sheet Cake keeps things simple: one pan, one batch of frosting, and no stacking required. That means less time fussing and more time enjoying. Plus, its flat surface becomes a perfect canvas for decorations—whether you keep it classic with a frosting layer and sprinkles or go bold with piping and themes.

Whether you’re making it for a child’s birthday, a backyard barbecue, or just craving a feel-good bake, the Sprinkle Sheet Cake delivers maximum impact with minimum effort.

🧁 Ingredients You’ll Need for the Perfect Sprinkle Sheet Cake

Creating the ultimate Sprinkle Sheet Cake starts with the right ingredients. Each component plays a key role in the flavor, texture, and festive appearance of this crowd-pleasing dessert. From the moist vanilla base to the smooth frosting and those irresistible rainbow sprinkles, here’s everything you need to make this colorful celebration cake from scratch.

🎂 For the Cake Batter

• 1 cup (226g) unsalted butter, softened – Gives your Sprinkle Sheet Cake a rich, buttery flavor and a tender crumb.
• 2 cups (400g) granulated sugar – Sweetens the cake and helps achieve a golden crust.
• 2 large eggs, at room temperature – Bind the batter and add richness.
• 2 ½ teaspoons pure vanilla extract – Delivers classic vanilla flavor; use high-quality extract for best results.
• ½ cup (120g) sour cream or plain yogurt – Keeps the cake ultra-moist. Full-fat versions are best.
• 2 ¼ cups (281g) all-purpose flour – Spoon and level for accuracy; too much can make the cake dense.
• 1 teaspoon baking soda – Provides lift for a light, fluffy texture.
• ½ teaspoon salt – Balances sweetness and enhances flavor.
• 1 cup (240ml) whole milk – Adds moisture and helps blend the batter smoothly.
• ½ cup (94g) rainbow sprinkles (plus more for topping) – Use rainbow jimmies to keep your Sprinkle Sheet Cake vibrant without color bleeding.

🍰 For the Vanilla Frosting

• ¾ cup (170g) unsalted butter, softened – The base of your smooth, creamy frosting.
• 3 cups (360g) confectioners’ sugar – Sweetens and thickens the frosting for easy spreading.
• 2–3 tablespoons (30–45ml) whole milk – Adjusts consistency; start small and add more if needed.
• 2 teaspoons pure vanilla extract – Adds warm, sweet notes to balance the sugar.
• ⅛ teaspoon salt – Cuts through sweetness for a balanced finish.

🔁 Substitutions & Smart Tips

• Butter: Always use unsalted to control salt content.
• Sour Cream/Yogurt: Full-fat plain Greek or regular yogurt are great alternatives.
• Milk: Whole milk is ideal, but 2% or oat milk also works.
• Sprinkles: Stick with rainbow jimmies—nonpareils will melt and discolor the batter.

This Sprinkle Sheet Cake recipe is surprisingly flexible and forgiving. You can tweak it to suit dietary needs without sacrificing the flavor or that festive look we all love.

🔪 Equipment & Prep Tips for a Foolproof Sprinkle Sheet Cake

Before you dive into mixing batter and sprinkling joy, make sure your kitchen is set up for success. Thankfully, baking a Sprinkle Sheet Cake doesn’t require professional tools—just a few reliable basics and a little prep work that makes a big difference in your final result.

🧰 Must-Have Tools

• 12×17-Inch Half Sheet Pan:
  This size ensures the cake bakes evenly and stays flat. Be sure the pan has 1-inch sides to accommodate the batter properly.
• Electric Mixer (Stand or Handheld):
  Either works—use a stand mixer for speed or a handheld mixer for control. Both whip the batter to fluffy perfection.
• Large Mixing Bowls (2):
  You’ll need one bowl for the wet ingredients and another for the dry. Stainless steel or glass is best for consistent mixing.
• Silicone Spatula & Balloon Whisk:
  Use the whisk to combine dry ingredients and the spatula for folding in sprinkles without crushing them or overmixing the batter.
• Wire Cooling Rack:
  Cooling your Sprinkle Sheet Cake on a rack allows air to circulate and prevents sogginess underneath the pan.

⚙️ Prep Tips That Guarantee Success

• Grease and Flour the Pan:
  Even if your pan is nonstick, take the extra step to grease it thoroughly and dust it lightly with flour. This ensures your Sprinkle Sheet Cake releases cleanly and keeps its crisp edges.
• Use Room Temperature Ingredients:
  Cold ingredients won’t mix evenly. Allow your butter, eggs, sour cream (or yogurt), and milk to sit at room temperature for 30–60 minutes before starting.
• Spoon and Level Your Flour:
  Avoid compacting flour by scooping. Spoon it into your measuring cup and level it off to prevent a dense cake.
• Avoid Overmixing the Batter:
  After adding flour and milk, mix just until everything is combined. Overmixing leads to toughness and can cause the sprinkles to bleed.
• Rotate the Pan Mid-Bake:
  If your oven has hot spots, rotate the sheet pan halfway through baking for even browning and consistent texture.
• Start Frosting Prep Early:
  While your Sprinkle Sheet Cake cools, prepare the vanilla frosting. This gives the frosting time to set up and makes decorating faster once the cake is ready.

Baking a flawless Sprinkle Sheet Cake is all about simple planning. With these tools and prep strategies, you’ll get an even rise, a tender crumb, and a gorgeous presentation every time—without the stress.

👩‍🍳 Step-by-Step Instructions for a Perfect Sprinkle Sheet Cake

Let’s get into the heart of it—making your Sprinkle Sheet Cake from start to finish. These step-by-step directions ensure a soft, flavorful cake with a smooth, creamy frosting and the perfect sprinkle finish. Even if you’re not a seasoned baker, you’ll nail this on your first try.

🔥 Step 1: Preheat and Prep the Pan

Preheat your oven to 350°F (177°C). Generously grease and lightly flour a 12×17-inch half sheet pan. This keeps your Sprinkle Sheet Cake from sticking and helps it bake evenly across the surface.

🧈 Step 2: Cream the Butter and Sugar

In a large bowl, use a handheld or stand mixer to beat 1 cup of softened butter on medium speed until smooth—about 1 minute. Add 2 cups of granulated sugar and beat until fluffy and light in color (2–3 minutes).

🥚 Step 3: Add the Eggs and Vanilla

Crack in 2 large eggs and pour in 2½ teaspoons of vanilla extract. Mix until fully combined, scraping down the bowl as needed to ensure even blending.

🥛 Step 4: Mix in the Sour Cream

Add ½ cup of sour cream (or full-fat plain yogurt) and beat on medium-high until smooth. This adds moisture and gives your Sprinkle Sheet Cake a tender, rich texture.

🥣 Step 5: Combine the Dry Ingredients

In a separate bowl, whisk together 2¼ cups of all-purpose flour, 1 teaspoon of baking soda, and ½ teaspoon of salt. This dry mix ensures the cake rises properly and stays fluffy.

🌀 Step 6: Alternate Dry Ingredients and Milk

Add half of the dry mixture to the wet batter and beat on low for 5 seconds. Pour in half of the 1 cup of whole milk and beat again. Repeat with the remaining flour mix and milk. Be careful not to overmix—stop as soon as the batter is smooth.

🌈 Step 7: Fold in the Sprinkles

Using a spatula, gently fold in ½ cup of rainbow sprinkles. Stick with jimmies (not nonpareils) to avoid color bleeding. This step gives your Sprinkle Sheet Cake its signature pop of color in every slice.

🧁 Step 8: Bake the Cake

Spread the batter evenly in your prepared sheet pan. Bake for 20–24 minutes, rotating once halfway through if needed. The top should be lightly golden, and a toothpick inserted in the center should come out clean.

❄️ Step 9: Cool Completely

Place the cake pan on a wire rack and let it cool fully—don’t rush this step! A warm cake will melt the frosting and ruin the finish.

🍦 Step 10: Make the Frosting

Beat ¾ cup of softened butter until creamy (about 2 minutes). Slowly add 3 cups of confectioners’ sugar, 2–3 tablespoons of milk, 2 teaspoons of vanilla, and ⅛ teaspoon of salt. Mix on low at first, then beat on high for 3 full minutes until fluffy. Adjust consistency as needed.

🎉 Step 11: Frost and Decorate

Spread the frosting evenly over the cooled Sprinkle Sheet Cake. Add extra sprinkles on top for a festive finish. Slice, serve, and enjoy the celebration!

🎨 Tips & Fun Variations for Your Sprinkle Sheet Cake

The beauty of a Sprinkle Sheet Cake isn’t just its eye-catching colors—it’s the versatility. Whether you’re baking for a birthday, customizing it for a dietary need, or just looking to elevate the flavor, here are smart tips and creative variations that make this cake endlessly adaptable.

✅ Pro Tips for Best Results

• Use the Right Sprinkles:
  Always use rainbow jimmies (the long, rod-like ones) for baking. They hold their color without bleeding. Save nonpareils and glitter for decorating the frosted top only.
• Don’t Overbake:
  Start checking the cake at 20 minutes. An overbaked Sprinkle Sheet Cake can turn dry. A clean toothpick in the center is your best test.
• Room Temperature Is Key:
  Cold butter, eggs, or milk can cause the batter to separate or bake unevenly. Set ingredients out 30–60 minutes before baking.
• For Clean Slices:
  Chill the frosted cake for 15–20 minutes before cutting. Use a sharp knife cleaned between cuts for neat, bakery-style squares.

🌈 Flavor Variations

• Lemon Vanilla Sheet Cake:
  Add 1 teaspoon of lemon zest and swap ½ teaspoon of vanilla for lemon extract to brighten the flavor.
• Almond Sprinkle Cake:
  Replace 1 teaspoon of vanilla with almond extract. Pair with sliced almonds and pastel sprinkles for a grown-up twist.
• Birthday Cake Remix:
  Fold in crushed chocolate sandwich cookies or mini chocolate chips along with sprinkles for a birthday party upgrade.

🧁 Size & Format Variations

• 9×13-Inch Pan Option:
  Pour the same batter into a 9×13-inch pan and bake for 35–38 minutes. Tent with foil halfway through to prevent over-browning.
• Cupcake Conversion:
  This Sprinkle Sheet Cake recipe makes about 24–28 cupcakes. Bake at 350°F for 17–20 minutes. Great for parties and portion control!
• Mini Sheet Cakes:
  Divide batter into two smaller pans to create two mini cakes—perfect for gifting or freezing.

🌱 Dietary Adaptations

• Gluten-Free Option:
  Use a 1:1 gluten-free baking flour blend with xanthan gum for best results.
• Dairy-Free Swap:
  Replace butter with vegan butter sticks and use oat or almond milk (with fat) instead of whole milk. Full-fat coconut yogurt works as a sour cream alternative.
• Reduced Sugar Version:
  Cut sugar by ¼ cup in both the cake and frosting. It’ll be slightly less sweet but still delicious.

This section helps readers tailor their Sprinkle Sheet Cake to fit their event, dietary needs, or flavor preferences—without compromising that nostalgic funfetti charm.
