Dark Chocolate Espresso Cake Ingredients
• Discover the magic of rich flavors!
For the Cake
- Unsalted Butter (1.5 sticks) – Adds moisture and richness; use salted butter if unsalted isn’t available.
- Espresso (3 double shots, 6 oz) – Infuses intense coffee flavors; substitute with strong brewed coffee for a milder taste.
- Cocoa Powder (0.5 C, 40g) – Provides chocolate flavor and dark color; use Dutch-processed for a richer flavor.
- Dark Chocolate (1 bar, 3.5 oz, Ghirardelli 72%) – Enhances the chocolate richness; select chocolate with at least 70% cacao for best results.
- Light Brown Sugar (1.25 C, 240g) – Ensures sweetness and moisture; opt for dark brown sugar for a deeper flavor.
- Bourbon Vanilla Extract (0.5 Tbsp) – Adds aromatic sweetness; regular vanilla extract works in a pinch.
- Kosher Salt (0.5 tsp) – Balances sweetness; avoid table salt as it might be too salty.
- Large Eggs (3) and Egg Yolks (2) – Provide structure and moisture; flax eggs substitute for a vegan option.
- All-Purpose Flour (1 C, 120g) – Builds structure in the cake; gluten-free flour can be used for a gluten-free version.
- Baking Soda (0.5 Tbsp) – Helps the cake rise; make sure it’s fresh for the best results.
For the Brown Butter Frosting
- Powdered Sugar (4 C, 450g) – Sweetener for frosting; adjust to taste for less sweetness.

Step‑by‑Step Instructions for Dark Chocolate Espresso Cake with Brown Butter Frosting
Step 1: Prep Baking Dish
Preheat your oven to 350°F (175°C) and prepare a 9×13 inch baking dish by greasing it with butter or using parchment paper for easy removal later. Set the dish aside while you gather and measure your ingredients, ensuring everything is within reach for a smooth baking process.
Step 2: Melt Butter and Espresso
In a medium saucepan, combine 1.5 sticks of unsalted butter and 6 oz of espresso over low to medium heat. Stir the mixture gently until the butter is fully melted and blended into the warm espresso, taking about 5 minutes. The aroma will envelop your kitchen, signaling that your Dark Chocolate Espresso Cake is already coming to life.
Step 3: Combine Chocolate
Add 0.5 cups of cocoa powder and 3.5 oz of chopped dark chocolate to the melted butter-espresso mixture in the saucepan. Stir continuously until everything is thoroughly melted and smooth, about 2-3 minutes. Remove from heat once you have a glossy chocolate mixture, setting it aside to cool slightly while you work on the other ingredients.
Step 4: Mix Dry Ingredients
In a large mixing bowl, whisk together 1.25 cups of light brown sugar, 0.5 tsp of kosher salt, and 0.5 tbsp of bourbon vanilla extract. Ensure that the sugar is well incorporated for an even distribution of sweetness. This will serve as the base for your Dark Chocolate Espresso Cake, so make sure the dry ingredients are lump-free.
Step 5: Combine Mixtures
Once the chocolate mixture has cooled down slightly, pour it into the bowl with your dry ingredients. Using a whisk or a spatula, mix until you achieve a smooth batter with no visible lumps, about 2 minutes. This step is crucial for achieving a rich and decadent flavor in your cake.
Step 6: Incorporate Eggs
Add 3 large eggs and 2 egg yolks to the chocolate mixture in the bowl. Whisk vigorously until everything is combined and the batter has a glossy appearance, about 1-2 minutes. The eggs will help to provide structure and moisture to your Dark Chocolate Espresso Cake, giving it that desired fudgy texture.
Step 7: Add Dry Ingredients
Gently fold in 1 cup of all-purpose flour and 0.5 tbsp of baking soda into the batter using a spatula or wooden spoon. Mix until just combined—be careful not to overmix, as this can affect the cake’s texture. You’ll want to see a few flour streaks remaining, as they will disappear during baking.
Step 8: Bake
Pour the batter into your prepared baking dish, spreading it evenly with a spatula. Bake in the preheated oven for 22-25 minutes, or until a toothpick inserted into the center comes out clean. You want your Dark Chocolate Espresso Cake to be set with a slight bounce, but still moist to ensure a delicious texture.
Step 9: Cool
Remove the cake from the oven and let it cool in the baking dish on a wire rack for about 15-20 minutes. Once slightly cooled, gently turn the cake out onto the rack to cool completely before frosting. This step is vital as frosting on a warm cake can result in a melted mess!
Step 10: Prepare Brown Butter
While the cake cools, start on the frosting by melting 1 stick of unsalted butter in a saucepan over low to medium heat. Stir continuously until it turns golden brown and has a nutty aroma—this should take about 5-7 minutes. Once browned, transfer it to a bowl and let it cool completely.
Step 11: Make Frosting
In a mixing bowl, combine your cooled brown butter with 4 cups of powdered sugar, gradually whisking them together. Add in 0.5 tbsp of vanilla extract, 0.5 tsp of kosher salt, and 3 tbsp of cold heavy cream. Beat until the frosting is smooth and creamy, taking care to achieve the desired consistency.
Step 12: Frost Cake
Once the cake has completely cooled, spread the luscious brown butter frosting evenly over the top using a spatula. Make swirls or decorative patterns if you like, and revel in the beautiful contrast that the frosting creates with the rich, dark cake. Now your Dark Chocolate Espresso Cake with Brown Butter Frosting is ready to be sliced and savored!

Dark Chocolate Espresso Cake with Brown Butter Frosting Recipe FAQs
What is the best way to select ripe ingredients for this recipe?
Absolutely! For the best results, choose high-quality dark chocolate with at least 70% cacao to ensure a rich flavor. When selecting espresso, opt for freshly ground beans if possible. Look for a robust aroma and avoid any signs of staleness. Fresh eggs are crucial; they should be clean and uncracked, and preferably at room temperature for easy incorporation into your batter.
How should I store the cake, and how long will it last?
Very! Store the Dark Chocolate Espresso Cake covered at room temperature for up to 3 days, ensuring it’s kept away from direct sunlight. If you’re saving it for later or have leftovers, refrigerate it for up to a week in an airtight container. To preserve its fluffy texture, let it cool completely before covering.
Can I freeze the Dark Chocolate Espresso Cake?
Absolutely! If you want to keep it longer, you can freeze the cake for up to 3 months. Here’s how: Wrap individual slices tightly in plastic wrap to prevent freezer burn, then place them in a resealable freezer bag. When you’re ready to enjoy it, simply thaw overnight in the fridge, then let it sit at room temperature for a bit before serving. You can even warm individual slices in the microwave for about 10-15 seconds!
What should I do if my cake is too dense or doesn’t rise?
Oh no! If your cake turns out too dense or fails to rise, it could be due to a few common issues. First, ensure that your baking soda is fresh, as old leavening agents lose their effectiveness. Additionally, be careful not to overmix the batter after adding the flour; mixing just until combined is key for a light texture. Lastly, the temperature of your ingredients can play a role—if your eggs and butter were too cold, it might affect the cake’s rise!
Are there any dietary considerations for this cake?
Very! The recipe is not vegan due to the use of eggs and dairy. However, you can substitute flax eggs (1 tablespoon of flaxseed meal + 3 tablespoons of water for each egg) for a plant-based alternative. If you’re concerned about allergens, ensure the chocolate doesn’t contain dairy, and check that the flour is gluten-free if you have gluten sensitivities. Enjoy the cake knowing it can be tailored to fit various dietary needs!
Can I make any substitutions to make this cake healthier?
Absolutely! If you want a healthier twist on the Dark Chocolate Espresso Cake with Brown Butter Frosting, consider using whole wheat flour instead of all-purpose flour for added fiber. Additionally, swapping half or all of the sugar with a sugar alternative like coconut sugar or a natural sweetener can reduce calories. For the frosting, using Greek yogurt or a reduced-fat cream cheese can lighten the frosting while retaining taste—an indulgent treat made a little lighter!
