Tips for Baking Success

To achieve the best results with your Copycat Costco Vanilla Cake, it's crucial to measure your ingredients accurately. Using a kitchen scale can help ensure precision, especially with flour and sugar. Remember to sift the flour to aerate it, which contributes to the cake's fluffy texture.

Another tip for success is to let your butter and eggs come to room temperature before mixing. This allows for better incorporation and a smoother batter. Additionally, avoid overmixing once you combine the dry and wet ingredients; this will help you maintain that light, airy quality in the finished cake.

Storing and Serving Tips

After you’ve baked and frosted your Copycat Costco Vanilla Cake, you may wonder how to store it. To keep the cake fresh, store it in an airtight container at room temperature for up to three days. If you need to keep it longer, refrigerate it for up to a week, but bring it back to room temperature before serving for the best flavor and texture.

When it comes time to serve, consider pairing your cake with a scoop of vanilla ice cream or a drizzle of chocolate syrup for an indulgent dessert experience. You can also garnish with fresh berries or mint leaves for a pop of color and a refreshing contrast to the sweet vanilla.

Ingredients

For the Cake

2 cups all-purpose flour
1 ½ cups sugar
½ cup unsalted butter, softened
1 cup whole milk
3 large eggs
2 ½ teaspoons baking powder
1 teaspoon vanilla extract
½ teaspoon salt

For the Frosting

1 cup unsalted butter, softened
4 cups powdered sugar
3 tablespoons heavy cream
2 teaspoons vanilla extract
Pinch of salt

Make sure all ingredients are at room temperature for the best results.

Instructions

Prepare the Cake Batter

Preheat your oven to 350°F (175°C). In a large bowl, cream together the softened butter and sugar until light and fluffy. Add the eggs one at a time, mixing well after each addition. Stir in the vanilla extract.

In another bowl, whisk together the flour, baking powder, and salt. Gradually add the dry ingredients to the wet mixture, alternating with the milk until fully combined.

Bake the Cake

Pour the batter into two greased 9-inch round cake pans. Bake for 25-30 minutes or until a toothpick inserted in the center comes out clean. Allow the cakes to cool in the pans for 10 minutes before transferring them to a wire rack to cool completely.

Prepare the Frosting

While the cakes are cooling, make the frosting. In a medium bowl, beat the softened butter until creamy. Gradually add the powdered sugar and mix until well combined.

Add the heavy cream, vanilla extract, and a pinch of salt. Beat until smooth and fluffy.

Assemble the Cake

Once the cakes are completely cooled, place one layer on a serving plate. Spread a generous amount of frosting on top. Place the second layer on top and frost the top and sides of the cake.

Serve and Enjoy

Slice the cake and serve. Enjoy the delicious flavors of this Copycat Costco Vanilla Cake!

Store any leftovers in an airtight container at room temperature for up to 3 days.

Frequently Asked Questions

One of the most common questions about this recipe is whether it can be made in advance. The answer is yes! You can bake the cake layers a day ahead and store them tightly wrapped. Just frost them on the day you plan to serve for the freshest taste.

Another frequently asked question is about substituting ingredients. If you’re looking for a dairy-free option, you can use almond milk or coconut milk in place of whole milk. For a richer flavor, consider substituting half of the sugar with brown sugar.

Serving Suggestions

This cake is delightful on its own, but there are numerous ways to elevate its presentation and flavor. Serving it with a side of whipped cream or a fruit compote can add a delightful contrast and make it feel even more special. For a more festive touch, add colorful sprinkles or edible flowers on top.

If you're planning a themed party, try customizing the cake with colored frosting or themed decorations. This adaptability makes it not only a delicious treat but also a beautiful centerpiece for your table.
