  • 1 cup granulated sugar

  • 1 cup packed light brown sugar

  • 4 large eggs, room temperature

  • 2 tsp vanilla extract

  • 2 tbsp instant espresso powder (or very strong coffee granules)

  • 1 cup buttermilk, room temperature

  • ½ cup brewed strong coffee, cooled

For the Caramel Sauce (homemade or store-bought)

For the Caramel Coffee Buttercream

  • 1 ½ cups unsalted butter, softened

  • 5 cups powdered sugar, sifted

  • 3 tbsp caramel sauce (from above)

  • 2 tbsp espresso or strong brewed coffee (cooled)

  • 2–3 tbsp heavy cream (as needed)

Step-by-Step Instructions

Step 1: Make the Caramel Sauce

  1. In a heavy-bottomed saucepan, heat sugar over medium heat, stirring constantly until it melts and turns amber.

  2. Add butter (careful, it will bubble up). Stir until melted.

  3. Slowly whisk in warm cream. Let bubble for 1–2 minutes.

  4. Remove from heat, add salt, and cool completely before using.

(Tip: This can be made 3 days ahead and stored in the fridge.)

Step 2: Bake the Coffee Cake Layers

  1. Preheat oven to 350°F (175°C). Grease and line three 8-inch cake pans with parchment.

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

  3. In a stand mixer, beat butter, granulated sugar, and brown sugar until fluffy (about 3–4 minutes).

  4. Add eggs one at a time, mixing well, then stir in vanilla.

  5. Dissolve espresso powder in cooled brewed coffee.

  6. Add dry ingredients alternately with buttermilk + coffee mixture, starting and ending with flour. Mix just until combined.

  7. Divide batter evenly among pans.

  8. Bake for 25–28 minutes, or until a toothpick comes out clean.

  9. Cool 10 minutes in pans, then transfer to wire racks to cool completely.

Step 3: Prepare the Buttercream

  1. Beat softened butter until creamy and pale (about 3 minutes).

  2. Gradually add powdered sugar, mixing on low to avoid a sugar cloud.

  3. Add caramel sauce and espresso, then beat until fluffy.

  4. Adjust with heavy cream for a spreadable consistency.

  5. Add a pinch of salt to balance sweetness.

Step 4: Assemble the Cake

  1. Level cooled cake layers with a serrated knife if needed.

  2. Place one layer on a cake board. Spread a layer of buttercream, then drizzle caramel sauce on top.

  3. Add the second cake layer and repeat with frosting and caramel drizzle.

  4. Top with the third cake layer. Spread a thin crumb coat of frosting over the cake, then chill for 20 minutes.

  5. Apply final coat of buttercream, smoothing sides with a spatula.

Step 5: Decorate

  • Warm caramel sauce slightly and drizzle over the edges for a dramatic drip effect.

  • Swirl extra buttercream on top using a piping bag.

  • Garnish with espresso beans, caramel shards, or a dusting of cocoa powder.

Expert Tips

  • Room temperature is key: Butter, eggs, and buttermilk should not be cold.

  • Espresso powder vs. instant coffee: Espresso has stronger flavor; instant coffee can be used but double the amount.

  • Chill before slicing: Refrigerating for 30 minutes before serving makes cleaner slices.

  • Don’t overbake: Coffee cakes can dry quickly; check early.

  • Salt matters: Salt enhances caramel’s depth—don’t skip it.

Variations

  1. Mocha Twist: Add cocoa powder to cake batter for a mocha flavor.

  2. Salted Caramel Version: Sprinkle flaky sea salt over each caramel drizzle layer.

  3. Cream Cheese Frosting Swap: Tangy cream cheese balances sweet caramel.

  4. Gluten-Free Option: Use a 1:1 gluten-free flour blend.

  5. Boozy Upgrade: Add 1–2 tbsp coffee liqueur (like Kahlúa) to buttercream.

Perfect Pairings

  • Drink: Espresso, cappuccino, or Irish coffee.

  • Sides: Vanilla gelato, chocolate mousse cups, or roasted nuts.

  • Occasions: Coffee dates, office parties, Thanksgiving, Christmas dessert table.
