Thick & Gooey Brownies

Prep Time15 mins
Cook Time25 mins
Total Time40 mins


  • 11 tablespoons butter 1 stick + 3 tablespoons
  • 1 1/4 cup sugar
  • 3/4 cup cocoa powder
  • 2 large eggs room temperature
  • 1 teaspoon vanilla
  • 1 teaspoon instant coffee or espresso
  • 1/2 cup flour
  • 1 tablespoon cornstarch
  • 1/4 teaspoon salt
  • 1 11.5 oz bag chocolate chunks


  • Preheat the oven to 325° and line a 9x9 pan with parchment paper. Set aside. 
  • In a small sauce pan over medium heat, melt butter. Once melted, add sugar and stir for 1-2 minutes. Sift in the cocoa powder, stir and let in cool for about 5 minutes.
  • Pour into a large bowl and add eggs one at a time, mixing well. Add in the vanilla and coffee. Add in the flour, cornstarch, and salt and mix until no flour packets remain.
  • Fold in the chocolate chunks and pour into prepared pan.
  • Bake for 25-35 minutes or the center is set. The toothpick test doesn't work well on these brownies because of the chocolate chunks.
  • Let fully cook before removing from pan and cutting.
