How to Make Dark Chocolate Espresso Cake with Brown Butter Frosting
Step 1: Preheat the Oven
Preheat the oven to 350ºF. Prep a 9×13 baking dish by greasing the sides and bottom. There’s no need for parchment paper since the cake will remain in the dish.
Step 2: Melt Butter and Espresso
In a small saucepan over low-medium heat, melt unsalted butter along with espresso. Once melted completely, remove from heat.
Step 3: Add Cocoa Powder and Chocolate
Immediately add cocoa powder and chopped chocolate into the saucepan. Stir until completely melted; some cocoa lumps may remain but will mix in later.
Step 4: Mix Dry Ingredients
In a large bowl, combine dark brown sugar, kosher salt, and bourbon vanilla extract.
Step 5: Combine Mixtures
Pour the melted chocolate mixture into the large bowl. Whisk until smooth.
Step 6: Add Eggs
Add eggs and egg yolks to the bowl. Whisk until glossy and smooth.
Step 7: Incorporate Flour
Add all-purpose flour and baking soda. Whisk until fully combined.
Step 8: Bake Cake
Pour batter into prepared baking dish. Bake for about 22-25 minutes or until a toothpick inserted comes out clean.
Step 9: Cool Completely
Allow the cake to cool completely before frosting it.
Step 10: Prepare Brown Butter
While the cake bakes, melt additional unsalted butter in a large saucepan over low-medium heat. Stir constantly while scraping the bottom of the pan.
Step 11: Brown Butter
When browned bits appear at the bottom of the pan and give off a nutty aroma, remove from heat. Transfer browned butter to a heatproof bowl to cool completely.
Step 12: Make Frosting
In a stand mixer with whisk attachment, mix cooled brown butter with powdered sugar at low speed for thirty seconds. Increase speed until fully combined; don’t forget to scrape down sides halfway through mixing.
Step 13: Finish Frosting
Add bourbon vanilla extract, kosher salt, and heavy cream. Whisk until smooth.
Step 14: Frost Cake
Spread frosting evenly across cooled cake before serving!

Common Mistakes to Avoid
Baking can be tricky, especially when making a Dark Chocolate Espresso Cake with Brown Butter Frosting. Here are some common mistakes and how to avoid them:
- Using Cold Ingredients: Always ensure your eggs and butter are at room temperature. Cold ingredients can prevent the batter from mixing properly, resulting in a dense cake.
- Not Measuring Ingredients Accurately: Baking is a science. Use a kitchen scale for dry ingredients like flour and sugar to ensure accuracy for the best results.
- Overmixing the Batter: Mixing too much after adding flour can lead to a tough cake. Mix just until combined for a light and airy texture.
- Ignoring Oven Temperature: Oven temperatures can vary. Always preheat your oven and consider using an oven thermometer for precise baking conditions.
- Skipping the Cooling Time: Allowing the cake to cool completely before frosting is crucial. If you frost while warm, it will melt the frosting and create a mess.
