What is Duff’s Cakemix?

Duff’s Cakemix is a do-it-yourself cake and cupcake decorating studio founded by Food Network star, Duff Goldman! We provide everything you need to bring your cake vision to life. Whether you follow one of our step-by-step guides or do your own thing, you get to focus on the most fun and creative part of cake-making – the decorating!

How long does the experience take?

Each reservation includes about an hour of decorating time. The entire expense from start to finish takes about an hour and 15 minutes.

Do I have to book in advance?

While we do accept walk-ins, as long as there is space available, we highly suggest booking in advance as we do tend to get pretty fully booked every day, especially on weekends.

What is your cancellation policy?

We do not charge a cancellation fee for standard reservations. However, as a courtesy to other guests who might otherwise be turned away, we kindly request as much notice as possible.

Do I need to choose my kit items ahead of time?

No need to order in advance, you can let us know your order once you arrive. However, if you’d like a 9″ or a two-tier cake please place your order in advance as we don’t always have them readily available.

Is there a minimum age for the activity?

Cake decorating is an amazing creative and social outlet for any age. We do recommend age 3 and up.

Is this a guided class experience?

Our standard experience is DIY (do-it-yourself), but we’ll give you instructions on how everything works upon arrival. We have step-by-step guides of our most popular designs, and members of Team Duff are always eager to share tips and tricks and answer questions. Even if you don’t fancy yourself an artist, it’s easier than you think to make beautiful, fun, cool looking cakes and cupcakes. We’ve seen over 100,000 people do it!

Will Duff be there when I visit?

Duff doesn’t have set times when he is in the studios, but he loves to stop by between filming, airplanes, and plying his own cake decorating craft with his friends at Charm City Cakes, so you never know when he might show up and give you some pointers, but be sure to tag @duffgoldman and @duffscakemix with your awesome creation and he just might holla back!

Is there a limit on the numbers of decorators?

Yes. We are currently only accepting reservations for up to 15 guests. That includes both people who are decorating and those who would rather watch. Unfortunately, we cannot accept ANY additional guests not accounted for in your reservation at this time.

What if I just want to come and watch, and do not plan to participate?

We are all about spending quality time with friends and family while decorating cakes. As long as the total amount of people in your group, including you, is 15 or fewer, you are more than welcome to just hang out and watch.

Can I bring in outside food?

We are not allowing outside food at this time. Beverages are totally fine to bring in as long as they do not contain alcohol.

Can I bring in alcohol?

No, unfortunately we are not permitted to allow guests to bring in their own alcohol.

Can I bring in my own decorations?

You are more than welcome to bring in your own balloons as that is the only kind of decorations our studios can accommodate at the moment.


Do I really have to wear a mask?

As per current California regulations masks are recommended but not required.

Can I book a private event?

Can I book an offsite event?

What is fondant?

Fondant, aka “sweet dough” or “rolled icing”, is a thick sugary, pliable dough. We cover all of our cakes in fondant which creates a smooth, beautiful surface for decorating. We also provide you with additional servings as part of your kit. It can easily be sculpted to create anything from the family dog to a unicorn horn to a beautiful flower. We offer a full assortment of colors, and of course you can always create your own by combining two or more of ours.


Unfortunately, we are not currently certified Kosher.


None of our cakes/cupcakes contain nuts as an ingredient. However, our cakes and cupcakes are baked at a kitchen where nuts are an ingredient in other products. For this reason, we cannot guarantee that their environment is completely nut free or free of cross-contamination. If you or one of your guests is highly allergic we recommend not eating our product. Please contact us for more information.

Vegan / gluten free

We are not currently offering vegan and/or gluten free options. Unfortunately, we cannot allow outside cakes to be brought into our studios at this time. Our fondant is vegan and gluten free. Our buttercream is gluten free, but not vegan.
