Step-by-Step Instructions
Step 1: Prep the Oven and Pans
Preheat oven to 350°F (175°C). Grease and line two 8-inch round cake pans with parchment circles.
Step 2: Mix Dry Ingredients
In a bowl, whisk flour, baking powder, baking soda, and salt. Set aside.
Step 3: Cream Butter and Sugar
In a large bowl, beat butter and sugar until light and fluffy (about 2–3 minutes). Add eggs one at a time, then mix in vanilla.
Step 4: Combine Wet and Dry
Mix in sour cream. Add dry ingredients in 2 parts, alternating with buttermilk, mixing just until combined.
Step 5: Bake
Divide batter evenly between pans. Bake for 25–30 minutes, or until a toothpick comes out clean.
Cool in pans 10 minutes, then turn out onto a rack to cool completely.
Step 6: Toast the Walnuts
In a dry skillet over medium heat, toast walnuts for 3–5 minutes until fragrant. Let cool.
Step 7: Make the Caramel Frosting
In a saucepan, melt butter and stir in brown sugar. Cook for 2 minutes while stirring.
Add milk/cream and bring to a gentle simmer for 1 minute, then remove from heat.
Cool for 5 minutes, then whisk in powdered sugar, vanilla, and salt until smooth and spreadable.
Step 8: Assemble the Cake
Place one cake layer on a plate. Spread caramel frosting and sprinkle toasted walnuts.
Top with the second layer. Frost the top and sides, then finish with more walnuts and optional caramel drizzle.
