Ingredients and Equipment

The ingredients for this Costco lemon cake recipe are straightforward and easily accessible. Here's what you'll need:

• All-purpose flour
• Baking powder
• Salt
• Unsalted butter
• Granulated sugar
• Eggs
• Lemon zest and juice
• Vanilla extract
• Buttermilk
• Cream cheese
• Powdered sugar

Equipment

To make this recipe, you'll need the following equipment:

• Two 9-inch round cake pans
• Mixing bowls
• Electric mixer
• Silicone spatula
• Cooling rack
• Offset spatula (for frosting)

Making the Lemon Cake

Preheat your oven to 350°F (175°C) and grease and flour your cake pans. In a medium bowl, whisk together the flour, baking powder, and salt. Set aside.

In a large bowl, cream the butter and sugar until light and fluffy. Beat in the eggs, one at a time, until well combined. Stir in the lemon zest, lemon juice, and vanilla extract. Gradually add the dry ingredients to the wet ingredients, alternating with the buttermilk, beginning and ending with the dry ingredients. Divide the batter evenly between the prepared cake pans.

Baking the Cake

Bake the cakes for 25-30 minutes, or until a toothpick inserted into the center comes out clean. Allow the cakes to cool in the pans for 10 minutes, then transfer them to a wire rack to cool completely.

While the cakes are cooling, prepare the cream cheese frosting. In a large bowl, beat the cream cheese until smooth. Gradually add the powdered sugar, beating until light and fluffy. Add lemon juice and vanilla extract, and beat until well combined.

Frosting and Assembling the Cake

Once the cakes have cooled completely, spread a layer of frosting on one cake and place the second cake on top. Spread the remaining frosting over the top and sides of the cake. For an extra touch, you can grate some lemon zest over the frosting for a pop of color and flavor.

Store the cake in an airtight container at room temperature for up to 5 days, or refrigerate for up to 1 week. Enjoy your homemade Costco-inspired lemon cake!

Tips for Success

Here are some tips to help you achieve the best results with this Costco lemon cake recipe:

• Room temperature ingredients: Ensure your butter, eggs, and buttermilk are at room temperature for easier mixing and better emulsion.
• Don't overmix: Once you add the dry ingredients, mix just until combined to avoid developing too much gluten, which can lead to a tough cake.
• Test for doneness: Use the toothpick test to ensure your cakes are fully baked. If the toothpick comes out with a few moist crumbs, the cakes are done.
• Cool completely: Make sure your cakes are completely cool before frosting to prevent the frosting from melting and becoming a mess.

This Costco lemon cake recipe is a delightful treat that's perfect for any occasion. With its moist and tender crumb, vibrant lemon flavor, and luscious cream cheese frosting, it's sure to become a favorite. So, gather your ingredients, preheat your oven, and get ready to enjoy a taste of Costco's famous lemon cake right from your own kitchen. Happy baking!
