Preparation Time

  • Assembly time: 15 minutes

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.

Serving Suggestions

  • Serve with coffee or tea for the perfect cozy dessert moment.
  • Add a scoop of vanilla ice cream for a “caramel sundae” vibe.
  • Garnish with caramel drizzle and whole walnuts for a bakery look.
  • Pair with fresh pears or apples for a fall-style dessert plate.
  • Serve chilled for cleaner slices, or slightly warm for extra caramel softness.

  • Cool layers completely before frosting to avoid melting.
  • Toast walnuts for stronger flavor and better texture.
  • If frosting thickens too fast, add 1–2 teaspoons milk to loosen.

  • Salted Caramel Walnut Cake: Add 1/2 teaspoon sea salt to the frosting and sprinkle flaky salt on top.
  • Chocolate-Caramel Twist: Add chocolate chips between layers or drizzle with melted chocolate.
  • Maple Walnut Version: Swap some brown sugar for maple syrup in the frosting.
  • Cupcake Version: Bake as cupcakes (18–20 minutes) and frost the same way.
  • Spice Cake Style: Add 1 teaspoon cinnamon and a pinch of nutmeg to the batter.
