I just love Halloween. I have been dreaming up these Monster Mash Halloween Cheesecake Bars for two Halloweens, and I finally spent an afternoon baking this yummy dessert along with a few other spooky treats like my Brimstone Brownies.
It sounds kind of silly, but my inspiration for this Halloween-themed cheesecake was a four-pack of gel food coloring at Walmart that was all Halloween colors. It had green, purple, orange, and black. I thought combining them all together would make a fun whimsical cheesecake.
How to make Monster Mash Halloween Cheesecake Bars
This cheesecake is perfect for a party. It’s made in a 9 x 13 pan. You can cut large bars and get about a dozen, or you can cut them smaller and get about 15-16 bars.
Before you begin, cover the bottom and sides of the 9 x 13 pan in foil, so you can easily lift out the cheesecake for cutting into squares.
I felt it was best to have an OREO cookie crust because a black crust would pair perfectly with these Halloween colors. I feel it works better than graham crackers because the creme fillings add some stickiness to help keep the crust together.
While the crust is cooling, make the cheesecake batter. Once you have made the batter, divide it into four bowls – one each for green, orange, black, and purple. You want bright vibrant colors, so just eyeball how much gel food coloring you need. I add a bit at a time until I get the color I want.
I did not want to really swirl the colors together. You can totally do that and randomly switch off adding a spoonful of each color of the batter. Instead, I just added one whole color at a time. Then, I gently swirled right at the color lines just a bit.
How do you prevent cracks in a cheesecake?
The secret to a good cheesecake without cracks is preventing it from getting too hot. I’ve read about placing the pan directly in a water bath while it cooks, but I don’t like that.
Awhile ago, I found What’s Cooking America recommends just setting a baking pan like a cookie sheet half filled with water on the lower rack and placing the cheesecake in the middle of the top rack with the top rack set at the middle level of the oven.
When I cook cheesecakes this way, they come out beautifully. This one had no cracks and baked to perfection.
To keep it looking lovely, I let the cheesecake cool on the counter for an hour or so, and then I put it in the fridge overnight.
Decorating your Monster Mash Halloween Cheesecake
After the cheesecake has set overnight, I pull it out of the fridge about an hour before I want to decorate it. You can decorate however you’d like. I decided to go with candy eyes and sprinkles in the same coordinating colors – orange, purple, and green.
How do you cut a cheesecake into bars?
My secret to cutting pretty squares of cheesecake is using a hot knife. I run it under hot water until the knife is completely hot. Then, I wipe off the water and slice. This will make pretty squares without any extra clumps of cheese.
