Black Sesame Cake

Three layers of black sesame cake coated with black sesame buttercream and topped with marshmallow webs. This is ultimate Halloween cake! 

Halloween Black Sesame Cake with marshmallow webs

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.

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!

Marshmallow helps for creating amazing stuff with a tad of imagination!

Heather (Delicious Not Gorgeous)

This is the most creative (flavor and look-wise) cake I’ve ever seen. I can’t wait to try this. I noticed that you’re in Pasadena? That’s where I’ve been for the past 20 years. I’m glad I came across your website. Can’t wait to try your many of your recipes.

Cheers to black sesame, I’ve been incorporating them into my diet to restore my hair (loosing it after gestation) and I can’t wait to try it in this cake. Thanks for inspiring…happy feasting!

ellie | fit for the soul

Your mom sounds like such a special lady and it’s awesome that she taught you how to appreciate yourself through small, yet meaningful actions like that. Amazingi stuff and I hope I can be half as involved in those areas with Selah since it takes a lot of work to break out of my indifferent-toward-holidays-type nature (I grew up like that, boooo, haha). And this is stunning, girl! I’m in love with the black sesame grey color.



Love the cake! Im trying to turn the recipe into metric, when it comes to the butter 10 tbsp equals 140ish g while 6 oz equals 170ish g (according to butter conversion tool) , which one is correct? Thank you.

    Maryanne Cabrera

    Hi Olivia, 10 tablespoons of butter is equal to 6 oz- about 170 grams.


Is milk used in the recipe? I don’t see it being mentioned in the instructions.

    Maryanne Cabrera

    I have updated the instructions. It was originally worded as “wet mixture” but I have changed it to be more specific. Thanks for pointing that out.


this looks incredible. how much in advance could i make the ‘web’…could i do it the day before serving…and if so, do you think the cake would need to be refridgeratred overnight, or just stored in an airtight container?

    Maryanne Cabrera

    You can assemble and decorate the cake the day before. I suggest storing it in the fridge because of the cream cheese in the frosting. Depending on the humidity of your fridge, you might want to keep the cake covered.

Cindy Rodriguez

I love, love, love this cake! It’s so my style and the marshmallow goop looks like so much fun to play with. Well done, Maryanne!

Amy Fothergill

how do you make the black sesame powder/flour? do you just grind the seeds?

    Maryanne Cabrera

    Yes, black sesame powder/flour is simply ground black sesame seeds. Major supermarkets usually sell black sesame flour.


Hi :) I made the cake but my frosting appears to be runny and not thick. Can I know how long you use to beat the cream cheese and butter? And how long you use to beat the black sesame paste, black sesame powder and icing sugar after that?


    Or is it because I did not use the icing sugar as per the amount in your recipe? Because I feel the frosting is quite sweet when I just added half of the amount of icing sugar in your recipe.


    And the measurement is in US or UK measurement?

    Maryanne Cabrera

    All the recipes on my site are in US measurements.

    Black Sesame Frosting: The cream cheese and butter is beat until smooth. You need to use the amount of confectioners’ sugar listed in the recipe. The sugar is responsible for thickening the frosting.


Hi! I was just wondering if i could skip the black sesame powder entirely. Could i substitute it with more black sesame paste or just put an equivalent amount of flour or just leave it entirely?

    Maryanne Cabrera

    I do not suggest omitting the black sesame powder. I do not recommend the substitutions as it will alter the ratios of this recipe.
