Three layers of black sesame cake coated with black sesame buttercream and topped with marshmallow webs. This is ultimate Halloween cake!
Growing up, Halloween was a big deal at my house. My mom would go all out on Halloween, decorating the house and getting the BEST candies to pass out.
Throughout elementary school, we had the same routine. At the end of September my mom would ask me what I’d like to dress up as. Come October, she would sew together my outfit, gather the perfect accessories and organize our neighborhood trick-or-treat group.
It’s been ages since I’ve asked my mom to make me a costume. Although, I bet once grandchildren are involved, she’ll have her sewing machine out as early as August to prepare.
Even though I don’t dress up anymore (mainly because Alex refuses to do matching costumes), at least I get to dress up the pups all I want! AND most importantly, I get to make Halloween inspired sweets and treats like this black sesame cake with marshmallow webs.
New twist on black velvet cake
This cake was inspired by the recent Food Network Magazine cover photo. Their feature Halloween cake is carrot cake covered in chocolate frosting and a marshmallow web. I was quite intrigued by the web, so I put my own spin on it.
At first I thought about making a “black” velvet cake. Good thing, I didn’t have black food coloring. As I searched through my pantry, I came across black sesame and this cake was born.
This recipe makes three 6-inch cake layers. I have a photo of the black sesame flour/powder I used in my black sesame shortbread post. If this black sesame cake seems too daunting, here’s an easier black sesame cupcake with matcha frosting.
Fill, stack, and frost the cake as usual. Let it chill in the fridge for about 20 minutes to allow the frosting to set and harden before you decorate it with the marshmallow webs.
This marshmallow web goop is super easy to make. Simply heat the marshmallows in the microwave.
You end up with this shiny, glossy, and super stringy goop. (It’s my new favorite thing and I want to cover all sorts of cakes with it! Thanks, Food Network Magazine!)
The marshmallow webs sort of look like silly string. You can add as much or as little as you want on the cake. I should have stopped here for an artistic minimal look- but I went a little overboard as shown in the photo below.
As you can see, this marshmallow web goop stuff can get pretty messy. If you’re not careful, it’ll end up everywhere… on your camera buttons, in your hair, all over the table, on the floor, on your phone!
It’s best to work on a surface you can easily wash.
Black Sesame Cake
If you’ve never had black sesame desserts- it tastes quite similar to peanuts. It’s very toasty and nutty in flavor. The cake isn’t that sweet, neither is the frosting.
The sugary marshmallows really help to balance out the flavors in this cake. Alex couldn’t get enough of it. Two thumbs up means it’s definitely a cake I’ll repeat for future Halloweens to come!
