Dark Chocolate Espresso Cake Ingredients
For the Cake
• Unsalted Butter (1 1/2 sticks / 170g) – Provides moisture and richness; substitute with margarine or vegan butter for a dairy-free option.
• Espresso (3 double shots / 6 oz) – Adds deep coffee flavor; use strong black coffee if espresso is unavailable.
• Cocoa Powder (1/2 C / 40g) – Enhances chocolate flavor and contributes to the structure; consider Dutch-process cocoa for a milder taste.
• Dark Chocolate Bar (1 / 3.5 oz, chopped) – Intensifies the chocolate flavor profile; swap with milk chocolate for a lighter sweetness.
• Light Brown Sugar (1 1/4 C / 240g) – Adds sweetness and moisture; white sugar can be used but will reduce flavor depth.
• Bourbon Vanilla Extract (1/2 Tbsp + 1 tsp) – Enhances flavor complexity; use pure vanilla extract as an alternative.
• Kosher Salt (1/2 tsp + 1/2 tsp) – Balances sweetness; feel free to substitute with sea salt.
• Large Eggs (3) & Egg Yolks (2) – Provide structure and moisture; replace with flax or chia eggs for a vegan option.
• All-Purpose Flour (1 C / 120g) – Gives structure to the cake; a gluten-free blend can be used if desired.
• Baking Soda (1/2 Tbsp) – Helps the cake rise; ensure it’s fresh for effective results.
For the Frosting
• Powdered Sugar (4 C / 450g) – Sweetens and thickens the frosting; can substitute with sugar alternatives for lower-sugar options.
• Heavy Cream (3 Tbsp / 45ml, cold) – Makes the frosting creamy; use coconut cream for a dairy-free version.
• Unsalted Butter (for browning) – Adds a nutty, rich flavor to the frosting, enhancing the overall cake experience.

Step‑by‑Step Instructions for Dark Chocolate Espresso Cake with Brown Butter Frosting
Step 1: Preheat and Prepare
Begin by preheating your oven to 350°F (175°C). Grease a 9×13 inch baking dish with butter or non-stick spray, ensuring all edges are covered to facilitate easy removal of the cake later. While this warms up, gather your ingredients to streamline your cooking experience and ensure you have everything on hand.
Step 2: Melt Butter and Espresso
In a small saucepan, combine 1 1/2 sticks of unsalted butter and 6 ounces of espresso over low-medium heat. Stir gently as the mixture melts, ensuring the butter combines with the espresso seamlessly. Once fully melted and smooth, remove the saucepan from heat, allowing the rich aromas to envelop your kitchen as you move on to the next step.
Step 3: Mix Chocolate and Cocoa
Add 1/2 cup of cocoa powder and a chopped dark chocolate bar (3.5 oz) to the melted butter and espresso mixture. Stir vigorously until smooth; there may be a few lumps remaining, which is fine. The combination will become glossy and fragrant, setting the stage for your indulgent Dark Chocolate Espresso Cake.
Step 4: Combine Sugar and Vanilla
In a large mixing bowl, whisk together 1 1/4 cups of light brown sugar, 1/2 teaspoon of kosher salt, and 1/2 tablespoon plus 1 teaspoon of bourbon vanilla extract. This mixture should be light and airy, forming a great base for your cake. The sweetness will balance the rich chocolate flavors that come next.
Step 5: Incorporate Chocolate Mixture
Pour the warm chocolate mixture into the bowl containing the sugar and whisk until the two mixtures blend beautifully and are fully combined. The color should become a deep chocolate hue while the texture remains silky and smooth. This luscious blend is what makes the Dark Chocolate Espresso Cake truly decadent.
Step 6: Add Eggs
Add three large eggs and two egg yolks to the chocolate mixture. Whisk vigorously until the mixture is glossy and thickens slightly, which will provide structure to your cake. The process should take about a minute, and the batter should feel rich and inviting as you prepare to include the dry ingredients.
Step 7: Incorporate Dry Ingredients
Sift in 1 cup of all-purpose flour and 1/2 tablespoon of baking soda directly into the bowl. Gently fold the dry ingredients using a spatula or wooden spoon until just combined, being careful not to overmix. The batter should be smooth with a slightly thick consistency, ready to pour into your prepared baking dish.
Step 8: Bake the Cake
Pour the cake batter into the greased baking dish, spreading it evenly with a spatula. Place it in the preheated oven and bake for 22-25 minutes, or until a toothpick inserted into the center comes out clean. The top should be set and slightly springy to the touch, indicating it’s perfectly baked.
Step 9: Cool Completely
Once baked, remove the cake from the oven and allow it to cool completely in the baking dish on a wire rack. This can take about 30-40 minutes. Ensuring the cake is fully cooled will help prevent the frosting from melting and guarantee a beautifully layered Dark Chocolate Espresso Cake with Brown Butter Frosting.
Step 10: Make Brown Butter Frosting
While the cake cools, prepare the frosting by browning 1/2 cup of unsalted butter in a small saucepan over medium heat. Stir continuously until the butter turns a golden amber color and emits a nutty aroma. This browning process is crucial for achieving the depth of flavor that complements your rich cake.
Step 11: Mix Frosting Ingredients
Transfer the browned butter into a large mixing bowl and allow it to cool slightly. Gradually add 4 cups of powdered sugar and 3 tablespoons of cold heavy cream, whisking until smooth and creamy. The frosting should be thick yet spreadable, ready to generously coat the cooled cake.
Step 12: Frost and Serve
Once the cake is completely cooled, frost it evenly with the brown butter frosting using a spatula. Take your time to create a lovely finish, and perhaps add a decorative touch, like chocolate shavings or a swirl. Now your Dark Chocolate Espresso Cake is ready to be sliced, served, and savored!

Expert Tips for Dark Chocolate Espresso Cake
• Prep Ingredients First: Organize and measure all ingredients before starting to streamline your baking process and reduce the chance of forgetting an important element.
• Melt Butter Gently: Be cautious while melting the butter with espresso; do so over low-medium heat to prevent burning, ensuring a rich, flavorful base for the cake.

What should I do if the cake is too dry?
If you find your cake is a bit dry, it could be due to overbaking. Always start checking for doneness around 22 minutes with a toothpick. If it comes out with moist crumbs, it’s ready!
