Ingredients

• 1 cup Unsalted butter
• 2 cups Granulated sugar
• 4 Large eggs
• 2 teaspoons Pure vanilla extract
• 2.5 cups All-purpose flour
• 2 teaspoons Baking powder
• 0.5 teaspoons Baking soda
• 0.5 teaspoons Salt
• 1 cup Whole milk
• 1.5 cups Chopped walnuts
• 1 cup Brown sugar
• 0.5 cup Heavy cream
• 2 cups Powdered sugar
• 0.5 cup Unsalted butter (for frosting)

Directions

Step 1

Preheat your oven to 350°F (175°C) and grease two 9-inch round cake pans. Line the bottoms with parchment paper for easy release.

Step 2

In a large mixing bowl, cream together 1 cup of unsalted butter and 2 cups of granulated sugar until light and fluffy, about 3-4 minutes.

Step 3

Add the eggs one at a time, mixing well after each addition. Stir in the vanilla extract.

Step 4

In a separate bowl, whisk together the flour, baking powder, baking soda, and salt.

Step 5

Gradually add the dry ingredients to the wet ingredients, alternating with the milk, beginning and ending with the dry ingredients. Mix just until combined.

Step 6

Fold in the chopped walnuts gently until evenly distributed.

Step 7

Divide the batter evenly between the prepared cake pans and smooth the tops with a spatula.

Step 8

Bake in the preheated oven for 30-35 minutes or until a toothpick inserted into the center comes out clean.

Step 9

Let the cakes cool in the pans for 10 minutes, then invert them onto a wire rack to cool completely.

Step 10

To make the frosting, melt 0.5 cups of butter in a medium saucepan over medium heat. Add the brown sugar and stir until dissolved, about 2-3 minutes.

Step 11

Stir in the heavy cream and bring the mixture to a boil. Remove from heat and let cool for 15 minutes.

Step 12

Gradually beat in the powdered sugar until the frosting reaches your desired spreading consistency.

Step 13

Place one cake layer on a serving plate, spread a layer of frosting on top, then place the second layer on top. Frost the top and sides of the cake.

Step 14

Decorate with additional chopped walnuts, if desired, and refrigerate for 30 minutes to set the frosting before serving.
