Ingredient Notes

• Brownie Mix – Any boxed brownie mix will work, but a richer brand like Ghirardelli makes the brownies extra fudgy.
• Pillsbury Ghost Sugar Cookies – These Ready to Bake! ghost cookies are what make the recipe festive. If you can’t find them, swap in another seasonal shape like pumpkins or bats.
• Ghost-Shaped Baking Pan – A shaped pan turns this dessert into a Halloween centerpiece. Mine was from TJ Maxx, but any ghost or spooky-themed pan will do.
• Halloween Sprinkles – Use your favorite spooky sprinkle blend. Look for mixes with fun shapes like ghosts, bats, or pumpkins for an extra festive touch.

Before You Bake

Do I need a ghost-shaped pan to make Ghost Brookie Cake?
No! The ghost pan makes it extra festive, but you can use a regular 9×13 pan. You’ll still get the brookie layers of brownies and cookies with a sprinkle topping.

When should I add the ghost cookies?
If your pan is shallow and bakes quickly, place the cookies on top before baking. For deeper pans, wait until the brownies are halfway baked, then add the cookies so they don’t overbake.

Can I make this ahead of time?
Yes. Bake the Ghost Brookie Cake the day before, let it cool completely, and store it covered at room temperature. Slice before serving or flip onto a platter for parties.

Ingredients

Scale 1x2x3x

• Ghost-shaped baking pan (mine is The Bake Shop by Masterclass Ghost Cake Pan – $6.99 at TJ Maxx)
• 1 box of your favorite brownie mix + ingredients on the box (I used Ghirardelli)
• 1 package Pillsbury Ready to Bake! Ghost Sugar Cookies
• Halloween sprinkles

Instructions

1. Preheat the oven to 350°F. Generously coat your ghost pan with baking spray (I like Baker’s Joy).
2. Mix up the brownie batter according to the package directions and spread it evenly into the pan. Scatter with Halloween sprinkles.
3. For shallow pans that bake quickly, place the ghost cookies right on top before baking. For deeper pans, wait until the brownies are about halfway done, then gently press the cookies in so they don’t overbake.
4. Once baked, let the brookie cake cool completely in the pan.
5. For parties or a group, flip the entire pan onto a platter so the ghost shape really shows off. Set it out whole and let your guests slice it into spooky squares.
