Ingredients
Cake Ingredients
- 1 cup butter, softened
- 2 cups sugar
- 2 large eggs, room temperature
- 1 cup cold mashed potatoes (without added milk and butter)
- 1 teaspoon vanilla extract
- 2 cups all-purpose flour
- 1/2 cup baking cocoa
- 1 teaspoon baking soda
- 1 cup 2% milk
- 1 cup chopped walnuts or pecans
Caramel Icing Ingredients
- 1/2 cup butter, cubed
- 1 cup packed brown sugar
- 1/4 cup evaporated milk
- 2 cups confectioners' sugar
- 1/2 teaspoon vanilla extract
Instructions
- Cream the butter and sugar: In a large bowl or stand mixer, beat the softened butter and sugar together until the mixture becomes light and fluffy, about five to seven minutes. This step aerates the batter, which prevents a dense cake.
- Add the eggs: Beat in the eggs one at a time, making sure each is well incorporated before adding the next. The batter might look curdled at this stage, especially if ingredients are cold, but it will even out.
- Mix in wet ingredients: On low speed, add the cold mashed potatoes and vanilla extract to the batter and mix gently to combine.
- Combine dry ingredients and milk: Whisk together the flour, cocoa powder, and baking soda in a separate bowl. Gradually add these dry ingredients into the batter alternating with the milk, starting and ending with the flour mixture. Beat well after each addition without overmixing.
- Stir in nuts: Fold in the chopped walnuts or pecans gently using a spatula to incorporate evenly without toughening the batter.
- Bake the cake layers: Divide the batter evenly between two greased and floured 9-inch round pans. Bake in a preheated 350°F oven for 25 to 30 minutes, or until a toothpick inserted in the centers comes out clean. Let cakes cool in pans for 10 minutes before transferring to wire racks to cool completely.
- Prepare the caramel icing: In a saucepan over low heat, melt the butter with the brown sugar until smooth. Stir in the evaporated milk and bring to a boil while stirring constantly. Remove from heat and cool to room temperature. Whisk in the confectioners' sugar and vanilla extract until smooth and spreadable.
- Assemble the cake: Place one cake layer on a serving plate and spread a generous layer of caramel icing on top. Add the second cake layer and spread icing across the top. Optionally, sprinkle extra nuts over the top. Note that the sides are typically left uniced unless desired otherwise.
Notes
- For best texture, ensure mashed potatoes are without added milk or butter to avoid altering the batter moisture content.
- Do not rush the creaming of butter and sugar to achieve a fluffy cake texture.
- The batter may look curdled after adding eggs, but this is normal and will resolve after adding other ingredients.
- Alternating with milk and dry ingredients prevents overmixing and helps distribute ingredients uniformly.
- You can double the icing recipe if you want to cover the sides of the cake for a more formal appearance.
- Use room temperature eggs and cold mashed potatoes for optimal mixing results.
