Ingredients

Scale

Brownie Cake

  • 340 grams Danish Creamery European Style Unsalted Butter (melted)
  • 300 grams granulated sugar
  • 300 grams light brown sugar (lightly packed)
  • 6 large eggs (room temperature)
  • 1 Tbsp vanilla extract
  • 80 grams unsweetened cocoa powder (spooned and leveled, Dutch processed)
  • 1 tsp fine sea salt
  • 210 grams all-purpose flour (spooned and leveled)

Chocolate Buttercream Frosting

  • 227 grams Danish Creamery Unsalted Butter (room temperature)
  • 227 grams cream cheese (room temperature)
  • 720 grams powdered sugar (spooned and leveled)
  • tiny pinch of salt
  • 60 mL heavy whipping cream (room temperature, reserving 1 Tbsp for just the chocolate buttercream)
  • 2 tsp vanilla bean paste
  • 20 grams unsweetened cocoa powder (spooned and leveled, Dutch processed)

Instructions

  1. Prepare the Brownie Batter: In a large mixing bowl, combine the melted Danish Creamery European Style Unsalted Butter with granulated sugar and light brown sugar. Mix thoroughly until well incorporated to achieve a smooth, glossy texture.
  2. Add Eggs and Vanilla: Beat in the eggs one at a time, ensuring each is fully incorporated before adding the next. Stir in the vanilla extract to enhance the flavor.
  3. Mix Dry Ingredients: In a separate bowl, sift together the unsweetened cocoa powder, fine sea salt, and all-purpose flour to ensure even distribution and to remove lumps.
  4. Combine Wet and Dry Ingredients: Gradually add the dry ingredients to the wet mixture, folding gently but thoroughly to combine without overmixing, preserving the fudgy brownie texture.
  5. Bake the Brownie Cake: Preheat the oven to 175°C (350°F). Pour the batter into prepared greased and lined baking pans. Bake for about 30 to 35 minutes or until a toothpick inserted near the center comes out with a few moist crumbs. Allow to cool completely before frosting.
  6. Prepare the Chocolate Buttercream Frosting: In a stand mixer bowl, beat the room temperature Danish Creamery Unsalted Butter and cream cheese together until smooth and fluffy, about 3-4 minutes on medium speed.
  7. Add Cocoa and Flavorings: Gradually sift in the powdered sugar and unsweetened cocoa powder. Add the tiny pinch of salt and vanilla bean paste. Mix on low speed to avoid cocoa powder flying out, then increase speed until well combined.
  8. Finish Frosting Texture: Slowly add the heavy whipping cream (reserving 1 Tbsp), beating continuously until the frosting is light, creamy, and spreadable. If necessary, use the reserved tablespoon of cream to adjust consistency.
  9. Assemble the Cake: Once brownies have fully cooled, spread a generous layer of chocolate buttercream over one brownie layer. Stack the second layer on top, then frost the top and sides evenly with the remaining buttercream. Smooth the finish or create decorative swirls as desired.
  10. Chill and Serve: Chill the assembled brownie cake for at least one hour to set the frosting before slicing. Serve at room temperature or slightly chilled for best flavor and texture.

Notes

  • Using room temperature eggs and dairy ingredients ensures even mixing and better texture.
  • Dutch processed cocoa powder gives a richer color and milder acidity compared to natural cocoa.
  • For a gluten-free version, substitute the all-purpose flour with a 1:1 gluten-free baking flour blend.
  • Store the brownie cake covered in the refrigerator for up to 4 days or freeze for longer storage.
  • Allow the cake to come to room temperature before serving to enhance flavor and soften the frosting.
