Ingredients

2 cups white sugar
2 cups all-purpose flour
1 cup hot water
2/3 cup creamy peanut butter
1/2 cup butter
1 cup vanilla yogurt
2 eggs
1 teaspoon baking soda
2/3 cup chunky peanut butter
1/2 cup butter
6 tablespoons milk
2 1/2 cups confectioners' sugar
1 tablespoon pure Michigan maple syrup
1/2 cup finely chopped walnuts
1/3 cup finely chopped pecans
1/4 cup sliced almonds
1 (8 ounce) package cream cheese, softened
1/2 cup confectioners' sugar
1 tablespoon milk
1 teaspoon almond extract
1 cup frozen whipped topping, thawed

Directions

1 Preheat the oven to 400 degrees F (200 degrees C). Grease and flour the bottom of a 15x20-inch rimmed baking sheet or jelly roll pan or line with parchment paper.
2 Sift white sugar and flour together into a bowl.
3 Combine hot water, creamy peanut butter, and ½ cup butter in a saucepan; bring to a boil, stirring frequently, until well blended. Remove from heat.
4 Combine yogurt, eggs, and baking soda in a separate bowl; add creamy peanut butter mixture in a steady stream, stirring constantly. Stir in flour mixture until batter is combined. Spread batter into the prepared baking sheet.
5 Bake in the preheated oven until center of cake springs back when touched lightly with a fingertip, about 20 minutes. Cool on a wire rack until warm.
6 Combine chunky peanut butter, ½ cup butter, and 6 tablespoons milk in a small saucepan; bring to a boil, stirring constantly. Reduce heat to low; stir in confectioners' sugar and maple syrup until sugar dissolves and frosting is smooth. Pour frosting over warm cake; sprinkle walnuts, pecans, and almonds over top. Cool completely.
7 Stir cream cheese, ½ cup confectioners' sugar, 1 tablespoon milk, and almond extract together in a bowl until smooth; fold in whipped topping until drizzle is creamy and runny. Drizzle over top of cooled cake.
