Ingredients

1 pound unsalted butter

1 pound plus 12 ounces semisweet chocolate chips, divided

6 ounces unsweetened chocolate

6 extra-large eggs

3 tablespoons instant coffee granules

2 tablespoons pure vanilla extract

2 1/4 cups sugar

1 1/4 cups all-purpose flour, divided

1 tablespoon baking powder

1 teaspoon kosher salt

3/4 cup smooth peanut butter

Directions

  1. Preheat the oven to 350 degrees F. Butter and flour a 12 by 18 by 1 1/2-inch sheet pan.
  2. Melt together the butter, 1 pound of chocolate chips, and the unsweetened chocolate in a medium bowl over simmering water. Allow to cool slightly. In a large bowl, stir (do not beat) together the eggs, coffee granules, vanilla, and sugar. Stir the warm chocolate mixture into the egg mixture and allow to cool to room temperature.
  3. In a medium bowl, sift together 1 cup of flour, the baking powder, and salt. Add to the cooled chocolate mixture. Toss the remaining 12 ounces of chocolate chips in a medium bowl with 1/4 cup of flour, then add them to the chocolate batter. Pour into the prepared sheet pan. Spoon the peanut butter over the top of the chocolate mixture and using a knife, swirl it through the chocolate mixture.
  4. Bake for 20 minutes, then rap the baking sheet against the oven shelf to force the air to escape from between the pan and the brownie dough. Bake for about 10 to 15 minutes more or until a toothpick comes out clean. Do not overbake! Allow to cool thoroughly, refrigerate, and cut into large squares.

First, this is a TON of brownies so I reduced it by half. The math got a little complicated since the recipe requires you to sub divide the flour and chocolate so I’m leaving the quantities below. Remember 6 oz chocolate chips = 1 cup. Second, it is really greasy so next time I will only use one stick of butter. Third, I baked it 15 extra minutes and the toothpick was still gooey but the brownies firm up when they cool. Fourth, save yourself a lot of clean up and line your pan with parchment paper. Last, it had a couple extra steps (chocolate chips mixed with the flour and interrupting baking to shake out air bubbles) I thought weren’t necessary.<div><br /></div><div>Half batch recipe:</div><div>Use a 12x8 pan</div><div><div>14 oz semi sweet chocolate, divided into 8 oz (1 &amp; 1/3 c) and 6oz (1 c)</div><div>3 oz (1/2 c) unsweetened chocolate </div><div>2 sticks butter (recommend only 1 stick)</div><div>1.5 tb instant coffee</div><div>1 tb vanilla</div><div>1 &amp; 1/8 c sugar</div><div>3/4 c flour, divided into 1/8 c and 2/3 c </div><div>1/2 tb baking powder </div><div>1/3 c peanut butter </div></div>
