As a professional baker I love to show you how you can make impressive desserts that really are super easy to make! Just like this brownie cake. It’s made in a bundt pan, but don’t be nervous about that! Make sure to read how to get a bundt cake out of a pan for my best tips and tricks!

So what exactly is a brownie cake? Simply put, this is a delicious dessert that combines the best of both worlds: the dense, fudgy texture of a brownie and the airy fluffiness of a cake. The result is a decadent treat that’s both rich and satisfying, with a deep, decadent chocolate flavor. To take it over the top it is frosted with my highly rated 5 minute brownie frosting.

Switch to a spatula, then fold in the vanilla extract until combined. Slowly add the flour, then the cocoa powder, along with the salt. Mix with the spatula until just combined.

TIPS FOR RECIPE SUCCESS

  • I use a 10 cup bundt pan for this recipe. If you have a smaller one it will take longer to bake, if you have a larger one it will take shorter.
  • When using the brownie frosting, you may need to thin it out with a few tablespoons of milk or cream to get it to a consistency where it will drizzle easily.
  • To prevent over mixing the batter, add the dry ingredients in small batches and mix until just combined.
  • For the best results, use high-quality ingredients such as real butter and high-quality cocoa powder like Ghirardellhi or Hersheys.
  • To avoid over baking the cake, check it after 45 minutes and continue to check it every 5 minutes until it is done. The cake is done when a toothpick or cake tester inserted in the center comes out with just a few moist crumbs.
  • Let the cake cool completely before adding frosting, as the frosting will not set properly if the cake is still warm.

Fudgy Chocolate Brownie Cake (From Scratch!)

This Fudgy Chocolate Brownie Cake is the perfect treat for any chocolate lover. It is rich, fudgy, chocolatey, and easy to make from scratch with simple pantry ingredients you already have on hand! It's made in a bundt cake but you can make it in a round cake pan too!

Ingredients

  • 1 cup (227 g) butter, unsalted
  • 4 oz (113.4 g) semi sweet chocolate
  • 1 cup (200 g) white sugar
  • 1 cup (200 g) brown sugar
  • 5 (5) eggs, large
  • 1 tbsp (1 tbsp) vanilla extract
  • 1 cup (120 g) all purpose flour
  • ¾ cup (65 g) unsweetened cocoa powder
  • ½ tsp (0.5 tsp) kosher salt

Instructions
 

  • Preheat the oven to 350° F and heavily grease an 8- 10 cup bundt pan.
  • In a microwave safe bowl combine the 1 cup butter and 4 oz chocolate. Microwave for 30 seconds at a time stirring in between until the chocolate is completely melted. Up to 90 seconds total. Let the chocolate cool for 5 minutes.
  • Add in 1 cup white sugar, 1 cup brown sugar and 5 eggs. Whip using a whisk or the whisk attachment of an electric mixer on high speed for 3 minutes.
  • Switch to a spatula and add in 1 tbsp vanilla and mix until combined. Next add in the 1 cup flour, 3/4 cup cocoa powder, and 1/2 tsp kosher salt. Mix until combined.
  • Pour the batter into the bundt pan and bake in the middle rack of the oven for 45 minutes for a fudgy cake or 50 minutes for less fudgy.
  • Cool in the pan for 15 minutes then flip over a wire rack to cool completely.
  • Drizzle with brownie frosting. If it is too thick, thin it out with 3 more tablespoons of milk or cream.

Notes

I used a 10 cup bundt pan here. If you use and 8 cup, it will take a little longer to bake, if you use a 12 cup it will take a little shorter.
