CAKE
1 cup butter, softened, plus more for greasing pans
1 cup granulated sugar
1 cup packed light brown sugar
4 large Pace Farm eggs
3 cups all-purpose flour, plus more for pans
2 teaspoons baking powder
1/2 teaspoons ground cinnamon
1/2 teaspoon salt
1/2 teaspoon baking soda
1 1/4 cups whole buttermilk
2 teaspoons vanilla extract
Peach Buttercream Frosting
Fresh peach slices
PEACH BUTTERCREAM FROSTING
1 1/2 cups butter
5 peaches, peeled and coarsely chopped (about 700g)
1/2 teaspoon salt
3 (450g) pkg. icing sugar
3 teaspoons vanilla extract
8 to 9 tablespoons whole milk
PEACH BUTTERCREAM FROSTING
Butter should be heated in a small, heavy saucepan over medium heat while being regularly stirred for 8 to 10 minutes, or until it starts to become golden brown. Pour butter into a little bowl that can withstand freezing as soon as you remove the pan from the heat. Cover and refrigerate for approximately an hour, or until the butter is cold and starting to harden.
Peaches should be thoroughly smoothed out in a food processor while this is going on. Peaches should be poured into a basin via a fine mesh sieve. Discard the sediments. Place peaches that have been drained in a small, heavy pot and heat. Cook for 10 to 15 minutes, stirring frequently, until reduced to 1/2 cup. After 20 minutes, let cool completely.
Using a powerful stand mixer set to medium speed, combine chilled butter and salt and beat until smooth. Add 8 tablespoons of milk, 8 tablespoons of reduced peaches (about 6 tablespoons), vanilla, and powdered sugar gradually, alternately, mixing thoroughly after each addition. If more milk is required, add it up to 1 tablespoon at a time, beating after each addition to get the appropriate consistency.
