Within the pages of the October issue of Martha Stewart Living [2], you'll find this irresistible hack for Halloween-themed brownies [3] without the frustration of decoration. Make Oreo monsters! According to the editors, "When you slice these brownies, you set loose a gaggle of red-eyed, chomping beasts — and your mob of hangry partygoers are the only ones who can defeat them." Heh — cute!

Here's how to re-create them:

1. Make a double batch of brownies [4] to fit in a 9-by-13 pan.
2. While brownies bake, break 16 cream-filled cookies, such as Oreos, in half. When brownies are hot out of the oven, press in the cookie pieces. Let cool.
3. Use royal icing [5] (or a premade tube of white icing) to dot two eyes on each cookie, and add red nonpareils for pupils.

According to Martha Stewart [6]'s test kitchen, their favorite, extrafudgy brownies recipe to use for the base is this Dark-Chocolate Spelt Brownies [7] recipe. They say the depth of flavor can't be beat!
