Meanwhile, place 2 cups all-purpose flour, 1 (3.4-ounce) box instant vanilla pudding mix, 1 1/4 teaspoons kosher salt, 1/2 teaspoon baking soda, and 1/4 teaspoon baking powder in a medium bowl and whisk to combine. Place 24 Nilla wafers in a large zip-top plastic bag, seal, and crush lightly with a rolling pin or bottom of a heavy pan into 1/4 to 1/2-inch pieces (about 1 cup).
