These butter mochi cake muffins are dense and chewy with a crispy buttery exterior that’s completely addicting! A spin on the classic Hawaiian dessert, this butter mochi recipe is baked with brown sugar, coconut milk, and toasted sesame seeds for rich toffee-like caramel and nutty notes.
The title for this recipe – butter mochi cake muffins – gets any confusion out of the way up front: these are absolutely dessert. They’re cake first, muffins second. Sure, you could call them cupcakes, but that would also be misleading, in my opinion. I don’t want you going into this expecting some sort of frostable cupcake. This mochi cake is dense and unbelievably chewy inside, with a slightly crunchy browned crust that together make a textural paradise. The muffin shape is there simply to ensure the highest ratio of delicious crispy browned crust. So mochi cake muffins it is, ok?
Also, because we’re calling them muffins, you can definitely definitely eat one for breakfast. These are magic muffins that might turn you into an irrational beast trying to savor and defend the muffins from being eaten by anyone but you. I would know.
I mentioned before that my neighbors brought over a batch of homemade gluten-free muffins the day we brought Ira home from the hospital two months ago. It was a batch of butter mochi cake muffins. There were at least a dozen muffins – plenty for everyone, but I knew how special these muffins were. They were my favorite kind of muffin and I didn’t have a recipe for them yet.
So when I caught Lucas at midnight eating on of these muffins in two bites like a monster, I snapped at him about how these weren’t meant to be midnight snacks you shove into your face like marathon fuel, they were special treats for our breakfast. I’d just birthed a 9lb baby and my hormones were all over the charts, but I had to protect my mochi muffins (our mochi muffins). After all, they were MY muffins (they definitely weren’t).
I’m fully aware how ridiculous that was and that I’m lucky he’s still my husband. But now you know: these butter mochi muffins are so delicious and addicting that you’ll be tempted to eat one right after another in huge bites, but, in my opinion, every last crumb is meant to be savored and enjoyed. Do either or both though. I won’t come after you in an unreasonable fit of rage, I promise.
What is butter mochi?
Butter mochi is a classic hawaiian dessert that bakes up as a dense chewy cake that’s typically sliced into pieces. My butter mochi recipe is a cross between classic Hawaiian butter mochi cake recipes and a mochi muffin that’s taking over cafes here in the East Bay Area.
Whenever I go for boba (often), I also grab a sesame-topped butter mochi muffin made by Third Culture Bakery. It’s one of my favorite snacks and, and $4 a pop, I’ve been looking to crack the recipe for years. Apparently so has everyone else because folks have been trying to sneak into his kitchen to steal the recipe!
When my neighbor showed up with a batch of similar mochi muffins I immediately texted for the recipe. Using his recipe as a jumping off point, I made several more batches – some with coconut sugar, some using evaporated milk – until settling on this very simple version that, in my mind, is mochi muffin perfection.
Butter mochi ingredients
The classic Hawaiian butter mochi cake uses eggs, sugar, butter, coconut milk, and mochiko (sweet rice flour). In my research, I also noticed many recipes call for evaporated milk or sweetened condensed milk, neither of which are ingredients I keep on hand nor prefer to use. My friend in Hawaii confirmed that his friend who is in charge of mochi cake for all their fundraisers and events uses both coconut milk and evaporated milk, while is auntie uses only coconut milk.
I went the latter route with just coconut milk because I prefer the simpler, cleaner ingredients.
The East Bay mochi muffin man uses Indonesian palm sugar and infuses his batter with pandan, both of which add distinctive notes to the muffin. Ultimately, I want a muffin I can make when the craving strikes using pantry staples. So I adapted and tweaked my recipe to capture that toffee-like flavor without hard-to-find ingredients.
These butter mochi muffins get their flavor from organic dark brown sugar and an extra splash of molasses. Combined with the sweet tropical notes from coconut milk and nutty toasted black and white sesame seeds, these muffins are exactly what I’ve been looking for.
How to make mochi cake muffins
The best part? They’re super easy to make. Add the wet ingredients to the dry ingredients, divide among a greased muffin tin, sprinkle with sesame seeds, and bake until golden brown with a slightly crispy shell.

*Organic dark brown sugar is richer and more caramel-y than conventional, but you an use conventional in a pinch!
**Any muffin tin will do, but for ultimate crispy exterior, I recommend a dark non-stick muffin tin.
***If using a light muffin tin, you may have to bake the muffins a little bit longer.
****If keeping them for longer, they'll lose their crispiness after a day or two in storage, but you can pop them in the oven for a few minutes to get them crispy again before eating.
