Butterscotch Caramel Cake

3 1/2 cups sifted cake flour
2 teaspoons baking powder
1/4 teaspoon salt
1 3/4 cups granulated sugar
1 3/4 cups light brown sugar, divided
1 1/4 cups butter, softened and divided
6 eggs
1 teaspoon vanilla extract
1 cup milk
1/2 cup evaporated milk

Preheat oven to 350°. Grease 2 (9-inch) round cake pans; line with wax paper. Combine flour, baking powder, and salt in a bowl; set aside. Place 1 3/4 cups granulated sugar, 1/4 cup light brown sugar, and 1 cup butter in a large bowl; beat with a mixer at medium speed 5 minutes or until well blended. Add eggs, 1 at a time, beating well after each addition. Stir in vanilla. Add flour mixture and 1 cup milk alternately to butter mixture, beginning and ending with flour mixture and beating at low speed after each addition. Pour into prepared pans; sharply tap pans once on counter to remove air bubbles.

Bake at 350° for 35 minutes or until wooden pick inserted in center comes out clean. Cool in pans on wire rack 10 minutes; remove from pans, and cool completely on wire rack. Place 1 layer on a cake plate.

Combine 1 1/2 cups brown sugar, evaporated milk, and 1/4 cup butter in a saucepan. Cook over medium heat, stirring until sugar is dissolved. Cook (without stirring) until a candy thermometer registers 238°. Transfer to a heat-resistant bowl, and beat 3 minutes or until thickened and easy to spread. Quickly spread filling over 1 cake layer on plate. Cover loosely with plastic wrap; chill 15 minutes or until set. Top with second layer. Frost cake. Chill 20 minutes or until frosting sets, then cover and chill 4 hours or overnight.

Caramel Cream Cheese Frosting
1/4 cup light brown sugar
10 tablespoon butter, divided
1/3 cup heavy whipping cream
8 ounces cream cheese, softened
1/2 teaspoon vanilla extract
Dash of salt
1 3/4 cups powdered sugar

Melt brown sugar and 4 tablespoons butter in a saucepan over medium heat. Stir until sugar dissolves. Bring to a boil over medium heat; remove from heat. Whisk in cream; blend well. Transfer to a heat-resistant bowl. Cool at room temperature, stirring occasionally.

Place remaining 6 tablespoons butter and cream cheese in a large bowl; beat with a mixer on medium-high speed until smooth. Beat in vanilla and salt. With mixer running, slowly pour in cooled brown sugar mixture; beat until smooth. Add powdered sugar gradually, beating well after each addition until completely smooth. Chill slightly for a firmer texture, stirring occasionally.

Frost cake and return to fridge until 10 minutes before serving. Leftovers must be kept refridgerated.
