Step 1

Preheat the oven to 350°F. Grease a 9x13-inch glass baking dish and line with parchment paper. Set it aside.

In the bowl of a stand mixer, combine eggs and vanilla extract. Using the whisk attachment on the mixer, whisk the egg mixture for 1 to 2 minutes.

Step 3

Add the cocoa powder, salt, and baking powder to the mixture and whisk for an additional minute.

Step 4

Meanwhile, in a large bowl, melt the butter in the microwave. Once melted, whisk the sugar into the hot butter.

Step 5

Add the hot butter/sugar mixture to the stand mixer bowl and mix until combined.

Step 6

Add the flour to the batter, mixing just until fully combined.

Step 7

Fold in the chocolate chips.

Step 8

Spread the brownie batter into the prepared baking dish.

Step 9

Bake for 35 to 40 minutes, until just a few crumbs, cling to a toothpick/knife when stuck in the center of the brownies. Remove from the oven and allow to cool completely.

Step 10

Cut into squares to serve.
