1 cup butter, room temperature
1 cup brown sugar
1 teaspoon vanilla extract
2 cups all purpose flour
1 teaspoon baking powder
1 teaspoon baking soda
1 teaspoon ground cinnamon
1/4 teaspoon salt
1/4 teaspoon cayenne pepper (see note)
1 12-ounce package semisweet chocolate chunks
Beat the butter and sugar in large bowl until fluffy. Beat in eggs 1 at a time, then beat in the vanilla.
Whisk the next 6 ingredients together and then add to the butter mixture, beating until just blended. Mix in chocolate chips.
Put the dough in the fridge until it is cold, at least 1 hour and up to 1 day.
Preheat oven to 350°F and line cookie sheets with silicone mats or parchment paper. Drop tablespoonfuls of the dough onto sheets about 2 inches apart.
Bake cookies until golden brown but still soft to touch, about 10 minutes. Cool for a few minutes, then place cookies on racks and cool.
