There's no need to choose between cake and pie. This Key lime cake with three flavorful layers and a Key lime cream cheese frosting is the best dessert mashup.
Ingredients
- 1/2 cup butter, softened
- 1/4 cup canola oil
- 2 cups sugar
- 2 large eggs, room temperature
- 1/4 cup Key lime juice
- 1 tablespoon grated Key lime zest
- 1 teaspoon vanilla extract
- 2-3/4 cups all-purpose flour
- 1-1/2 teaspoons baking powder
- 1/2 teaspoon baking soda
- 1/2 teaspoon salt
- 1-1/2 cups whole milk
- FROSTING:
- 1/2 cup butter, softened
- 1 package (8 ounces) cream cheese, softened
- 3 cups confectioners' sugar
- 2 tablespoons heavy whipping cream
- 2 tablespoons Key lime juice
- 2 teaspoons grated Key lime zest
- 1/2 cup graham cracker crumbs, optional
Directions
- Preheat oven to 350°. Line 3 greased 8-in. round baking pans with parchment, set aside.
- In a large bowl, cream sugar, butter and oil until light and fluffy, 5-6 minutes. Beat in eggs, one at a time, until fluffy, 2-3 minutes. Beat in lime juice, lime zest and vanilla extract. Combine flour, baking powder, baking soda and salt; add to creamed mixture alternately with milk, beating well after each addition. Pour batter into prepared cake pans. Bake until a toothpick inserted in the center comes out clean, 35-40 minutes. Cool 10 minutes in pans; remove to wire racks to cool completely.
- In a large bowl, beat butter and cream cheese at medium speed until smooth, 3-4 minutes. Reduce mixer speed to medium-low; beat in confectioners' sugar, cream, lime juice and lime zest. Increase speed to medium-high; beat until well combined.
- Place 1 cake layer on a serving plate; frost top with 3/4 cup frosting. Repeat layers. Top with remaining cake layer. Frost top and sides of cake with remaining frosting. If desired, sprinkle with graham cracker crumbs.

Unlike the pie, this Key lime cake is topped with a decadent cream cheese frosting. You can top it with graham cracker crumbs as a nod to the original pie crust. —Taste of Home Test Kitchen
