Sprinkle Sheet Cake Recipe

All-purpose flour: The base of the cake, providing structure and texture.

Granulated sugar: Adds sweetness and helps to create a tender crumb.

Unsalted butter: Adds richness and moisture to the cake.

Eggs: Provide structure and stability, helping the cake to rise.

Whole milk: Adds moisture and helps to create a tender crumb.

Vanilla extract: Adds a warm, sweet flavor to the cake.

Rainbow sprinkles: Add a fun, colorful element to the cake.

Baking powder: Helps the cake to rise and become fluffy.

Salt: Enhances the flavors of the other ingredients.

When folding in the sprinkles, be gentle to avoid overmixing, which can cause the colors to bleed into the batter. This ensures that the cake has vibrant, distinct rainbow colors throughout.

• all-purpose flour - Substitute with cake flour: Cake flour has a lower protein content, which results in a lighter and more tender cake.

• all-purpose flour - Substitute with gluten-free flour blend: For those with gluten intolerance, a gluten-free flour blend can be used to achieve similar results.

• granulated sugar - Substitute with coconut sugar: Coconut sugar has a lower glycemic index and adds a slight caramel flavor.

• granulated sugar - Substitute with honey: Honey can add moisture and a different flavor profile, but reduce the milk slightly to balance the liquid content.

• unsalted butter - Substitute with margarine: Margarine can be used as a dairy-free alternative, though it may slightly alter the flavor.

• unsalted butter - Substitute with coconut oil: Coconut oil can add a subtle coconut flavor and is a good dairy-free option.

• eggs - Substitute with flax eggs: Mix 1 tablespoon of ground flaxseed with 3 tablespoons of water per egg for a vegan alternative.

• eggs - Substitute with applesauce: Use ¼ cup of unsweetened applesauce per egg to add moisture and a slight apple flavor.

• whole milk - Substitute with almond milk: Almond milk is a good dairy-free alternative that can be used in the same quantity.

• whole milk - Substitute with buttermilk: Buttermilk adds a tangy flavor and can make the cake more tender.

• vanilla extract - Substitute with almond extract: Almond extract provides a different but complementary flavor to the cake.

• vanilla extract - Substitute with maple syrup: Maple syrup can add a unique flavor and sweetness.

• rainbow sprinkles - Substitute with chocolate chips: Chocolate chips add a different texture and flavor to the cake.

• rainbow sprinkles - Substitute with crushed nuts: Crushed nuts provide a crunchy texture and a nutty flavor.

• baking powder - Substitute with baking soda and cream of tartar: Use ¼ teaspoon of baking soda and ½ teaspoon of cream of tartar for each teaspoon of baking powder.

• baking powder - Substitute with self-rising flour: Self-rising flour already contains baking powder and salt, so adjust the recipe accordingly.

• salt - Substitute with sea salt: Sea salt can be used in the same quantity and may add a slightly different flavor.

• salt - Substitute with kosher salt: Kosher salt can be used in the same quantity and provides a different texture.

• Allow the cake to cool completely on a wire rack before storing. This prevents condensation from forming inside the storage container, which can make the cake soggy.

• Once cooled, cut the cake into individual servings. This makes it easier to grab a piece whenever you have a craving for something sweet.

• Wrap each piece tightly in plastic wrap. This helps to keep the cake moist and prevents it from drying out.

• Place the wrapped pieces in an airtight container. This adds an extra layer of protection against air and moisture, keeping your dessert fresh for longer.

• Store the container in the refrigerator if you plan to eat the cake within a week. The cool temperature will help maintain its texture and flavor.

• For longer storage, place the wrapped pieces in a freezer-safe bag or container. Label it with the date so you know how long it has been stored.

• When you're ready to enjoy a piece, remove it from the freezer and let it thaw at room temperature for about 30 minutes. If you're in a hurry, you can also microwave it for a few seconds, but be careful not to overheat and dry out the cake.

• If you prefer to store the cake whole, wrap the entire cake tightly in plastic wrap, followed by a layer of aluminum foil. This double wrapping helps to lock in moisture and protect against freezer burn.

• Place the wrapped cake in a large, airtight container or a freezer-safe bag. Again, label it with the date for easy reference.

• To thaw a whole cake, transfer it to the refrigerator the night before you plan to serve it. This slow thawing process helps to maintain the cake's texture and flavor.

• Once thawed, let the cake sit at room temperature for about 30 minutes before serving. This brings it back to its optimal texture and flavor, making it taste just as fresh as the day you baked it.

• Preheat your oven to 300°F (150°C). This gentle heat will warm the cake without drying it out.
• Place the leftover sprinkle sheet cake on a baking sheet. If the cake is already sliced, arrange the slices with a bit of space between them to ensure even heating.
• Cover the cake loosely with aluminum foil. This helps retain moisture and prevents the top from becoming too crispy.
• Heat the cake in the oven for about 10-15 minutes. Check for warmth by inserting a toothpick or a small knife into the center. If it comes out warm, the cake is ready.
• For a quicker method, use the microwave. Place a slice of cake on a microwave-safe plate.
• Cover the cake slice with a damp paper towel. This will help keep the cake moist.
• Microwave on medium power for 20-30 seconds. Check the cake and continue heating in 10-second intervals until it reaches your desired warmth.
• If you prefer a slightly crispy texture, use a toaster oven. Preheat the toaster oven to 300°F (150°C).
• Place the cake slice on a piece of parchment paper or directly on the toaster oven rack.
• Heat for about 5-7 minutes, checking frequently to avoid over-toasting. The edges should be slightly crispy while the inside remains soft.
• For an indulgent twist, reheat the cake in a skillet. Melt a small amount of butter over medium heat.
• Place the cake slice in the skillet and heat for 1-2 minutes on each side. This method gives the cake a delightful buttery crust.
• Serve the reheated sprinkle sheet cake with a scoop of vanilla ice cream or a dollop of whipped cream for an extra treat.

• Oven: Used to bake the sheet cake at the specified temperature of 350°F (175°C).

• Sheet pan: The baking pan where the cake batter will be poured and baked.

• Mixing bowl: Used to combine and mix the ingredients.

• Whisk: Helps in mixing the dry ingredients together.

• Electric mixer: Ideal for creaming the butter and sugar until light and fluffy, and for beating in the eggs.

• Measuring cups: Used to measure out the flour, sugar, and milk accurately.

• Measuring spoons: Used to measure out the vanilla extract, baking powder, and salt.

• Spatula: Useful for folding in the sprinkles and scraping down the sides of the mixing bowl.

• Toothpick: Used to check if the cake is done by inserting it into the center of the cake.

• Wire rack: Allows the cake to cool completely in the pan.

• Non-stick spray: Used to grease the sheet pan to prevent the cake from sticking.

• Flour sifter: Helps in sifting the flour to remove any lumps and to aerate it.

Pre-measure ingredients: Measure and prepare all ingredients before you start. This will streamline the baking process and prevent any last-minute scrambles.

Use a stand mixer: A stand mixer can save you time and effort when creaming butter and sugar or mixing batter.

Room temperature ingredients: Ensure your butter and eggs are at room temperature. This helps them blend more easily and speeds up the mixing process.

Line the pan: Instead of greasing and flouring, line your sheet pan with parchment paper for quicker cleanup.

Batch tasks: Combine similar tasks, like measuring dry ingredients together, to save time.
