- 2/3 cup unsalted butter, softened
- 2 cups brown sugar
- 3 eggs
- 1 teaspoon vanilla extract
- 2 cups matzo cake flour
- 1/2 teaspoon kosher salt
- 3/4 cup chocolate chips
- 1/2 cup chopped pecans
- Preheat oven to 350 degrees F (175 degrees C). Grease a 9×13-inch baking dish and line with parchment paper.
- Beat butter in a bowl using an electric mixer until smooth and fluffy; add brown sugar and beat until creamy. Beat eggs, 1 at a time, into creamed butter mixture, beating well after each addition. Beat in vanilla extract.
- Sift flour and salt together in a bowl; slowly stir into the creamed butter mixture just until dough is mixed. Fold chocolate chips and pecans into the dough; press into the prepared baking dish.
- Bake in the preheated oven until lightly browned and edges begin to crisp, 25 to 30 minutes.
