Monster Halloween Brownies

These Monster Halloween Brownies are a fun and easy Halloween treats that will have the kids squealing with joy as they gobble them up.


1 box of brownie mix and the ingredients needed to make them (I used Pillsbury Funfetti Brownie Mix)

1 can of vanilla or white frosting (you will need less than a 1/3 of the container for 8 of these)

Regular size marshmallows

various food colors

various candies

Mini M&M'S, Candy Coated Sunflower Seeds, chocolate jimmies, and Wilton Rainbow Chip Crunch Sprinkles.


Mix the brownie mix according to the directions, but I substituted the oil out and put in unsweetened applesauce. This makes the brownies look a little different on top and a little denser, but healthier and lower in calories. Since this is easily mixed by hand, the bowl can easily go in the dishwasher. No dishes to hand wash. I baked the brownies in a 9x13 pan with a foil sling sprayed with baking spray. No pan to wash.

Within about 15 minutes you can easily lift the brownies out of the pan in the foil sling and let continue to cool on baking rack. I actually was able to begin the next step while the brownie was still a little warm. Now since my pan curves up in the corners, the bottom of the brownie is thinner on each of the short sides, so I cut that part off for snacking later. With a round cookie cutter, I was able to cut out 8 brownies. If you your pan is even all the way to the sides you will be able to cut out 10 to 12. You could also just cut them and leave them squares if you want!

After the brownies are baked, cooled, and cut, the decorating part takes no more than 15 minutes!

Put the little round brownies on a piece of wax paper to work with making clean up a snap!

Sit a marshmallow on top of the brownie, no need to stick it down with anything, it will stick from the melted frosting in the next step.

You will need 2-3 teaspoons of frosting per color if you are making 3 colors. Melt the canned frosting in the microwave in a glass bowl for about 20 seconds. I used Betty Crocker Whipped Frosting that I had leftover, and it did separate in the microwave, but easily mixed back together when adding the coloring.

Spoon the melted frosting to cover the marshmallow and drip down the sides a little, that will adhere the marshmallow to the brownie. After 3 or 4 brownies are covered, go back to the first and the icing will still be tacky enough to stick on your candy pieces. If you wait too long the icing will dry and the candy won't stick. If the candy wants to slide down the icing, wait a couple more minutes. You will know it is perfect when the candy sticks on and doesn't slide anywhere. This is quite easy when the frosting is at the right tackiness!
