Directions for Cake Costco Copy Cat
Let’s bake this Cake Costco Copy Cat—a perfect bakery-style cake!
Prep the Oven and Pans
I preheat the oven to 350°F (175°C) and grease two 9-inch round cake pans, lining the bottoms with parchment for easy release of this fluffy vanilla cake.
Mix Dry Ingredients
In a medium bowl, I whisk 2½ cups flour, 2 tsp baking powder, ½ tsp baking soda, and ½ tsp salt, ensuring even leavening for a light celebration cake.
Cream Butter and Sugar
In a large bowl, I cream ¾ cup butter and 1½ cups sugar with a mixer until pale and fluffy, about 3–4 minutes, for a tender Cake Costco Copy Cat crumb.
Add Eggs and Vanilla
I beat in 3 eggs one at a time, scraping the bowl, then add 2 tsp vanilla extract for that signature bakery-style cake flavor.
Combine Wet Ingredients
In a small bowl, I mix ¾ cup sour cream and ¾ cup milk until smooth, ready to blend into this fluffy vanilla cake batter.
Mix the Batter
I alternate adding the flour mixture and sour cream mixture to the butter mixture, starting and ending with flour, mixing on low until just combined to keep this celebration cake tender.
Bake the Layers
I divide the batter evenly between the pans, smooth the tops, and bake for 30–35 minutes until a toothpick shows a few moist crumbs. I cool the cakes in pans for 10 minutes, then transfer to a wire rack to cool completely for this bakery-style cake.
Make the Frosting
I whip 2 cups heavy cream with ½ cup powdered sugar, 1 tsp vanilla, and 1 tbsp pudding mix (if using) until stiff peaks form, creating a stable frosting for this fluffy vanilla cake.
Assemble the Cake
I place one cake layer on a plate, spread with whipped cream and sliced strawberries (if using), top with the second layer, and frost the top and sides with whipped cream, swirling for a festive Cake Costco Copy Cat look.
