Fudgy Chocolate Chip Brownies

Method

1. Position a rack in the middle of the oven and preheat to 350° F. Oil an 8 x 8-inch square pan and then line the bottom with parchment paper. Do not oil the paper.
2. Place a wire mesh strainer over a medium bowl. Add the all-purpose flour, pastry flour, cocoa, granulated sugar, whole cane sugar, arrowroot or cornstarch, baking powder, and salt to the strainer and stir with a whisk to sift the ingredients into the bowl. (If any small bits remain in the strainer, add them to the mixture in the bowl.) Whisk to aerate the mixture.
3. Whisk the oil, maple syrup, nondairy milk, vanilla, and chocolate extract, if using, in a separate medium bowl until completely combined. Pour into the dry ingredients and mix with a silicone spatula until the batter, which will be thick, is smooth. Allow the batter to rest for ten minutes.
4. Stir the chocolate chips and nuts, if using, into the batter. Spoon the batter into the prepared pan, and spread into an even layer with a metal spatula.
5. Bake for 23 minutes until the top is set and dry and the sides have pulled just slightly away from the pan.
6. Remove the pan from the oven and set on a cooling rack. Immediately insert a wooden tester diagonally into the brownies. The tester will be coated with batter, but not wet. If necessary, bake for another minute.
7. Cool to room temperature. The middle of the cake will sink as it cools; don’t worry. Once cold you can push the sides down to level the cake if you like. Refrigerate until very cold before cutting into squares.

Keeping: Refrigerate the brownies in a covered container, in layers separated by parchment, for up to three days, or freeze for up to one month. Defrost unwrapped or eat straight out of the freezer.
