I always whip up brownies in muffin pans ’cause they turn out crispy on the outside and chewy on the inside. No more fighting over the corners, lol! I use 2 boxes of brownie mix to make 24 brownie cupcakes, and I toss in an extra egg for extra gooeyness. Spray the pans really well with nonstick spray, and they’ll pop out easily with a butter knife. Bake ‘em at 350°F for 20 minutes, and let ‘em cool for 5 minutes before you take ‘em out of the pans.
