How to Make Gold Rush Peanut Butter Cake

  1. **Prepare the Cake:** Preheat oven to 350°F (175°C). Grease and flour three 9-inch round cake pans.
  2. In a large mixing bowl, cream together 1 cup (2 sticks) unsalted butter and 1 cup creamy peanut butter until light and fluffy.
  3. Add 1 ½ cups packed light brown sugar and mix until well combined.
  4. Beat in 4 large eggs one at a time, mixing well after each addition.
  5. In a separate bowl, whisk together 3 cups all-purpose flour, 2 teaspoons baking powder, and ½ teaspoon salt.
  6. Gradually add the dry ingredients to the wet ingredients, alternating with 1 cup milk, beginning and ending with the dry ingredients. Mix until just combined.
  7. Stir in 1 teaspoon vanilla extract.
  8. Divide the batter evenly among the prepared cake pans.
  9. Bake for 40-45 minutes, or until a wooden skewer inserted into the center comes out clean.
  10. Let the cakes cool in the pans for 10 minutes before inverting them onto a wire rack to cool completely.
  11. **Prepare the Filling:** In a medium bowl, beat together ½ cup (1 stick) softened margarine, 8 ounces softened cream cheese, and 2 cups powdered sugar until smooth and creamy.
  12. Stir in 1 teaspoon vanilla extract and ½ cup creamy peanut butter.
  13. **Prepare the Frosting:** In a saucepan over medium heat, combine ½ cup (1 stick) margarine, 1 cup packed light brown sugar, and ½ cup Karo syrup. Bring to a boil, stirring constantly.
  14. Remove from heat and stir in ½ cup milk, 2 cups powdered sugar, 1 teaspoon vanilla extract, and ½ cup creamy peanut butter until smooth and creamy.
  15. **Assemble the Cake:** Once the cake layers are completely cool, frost the top of one layer with a generous amount of the peanut butter filling. Top with the second layer and frost with the remaining filling. Place the final layer on top and frost the entire cake with the brown sugar frosting.
  16. Refrigerate for at least 30 minutes before serving to allow the frosting to set.
