Cassava Cake with Custard Topping made with grated cassava and coconut milk. Soft and moist with a creamy flan topping, this classic Filipino treat is the ultimate snack or dessert. And it’s naturally gluten-free, too!

As a Filipino in the U.S. without complete access to indigenous ingredients, I, at times, have to make substitutions when recreating the Filipino dishes I grew up with. A good example would be my chicken tinola and ginisang munggo with chicharon; I usually use spinach leaves because the traditional malunggay or ampalaya leaves are not always easy to find even at Asian supermarkets.
These later years, however, have seen a considerable variety of Filipino food products now being imported and made available for us Filipino-American consumers. On most occasions, I have to forgo of “freshness” as these items come pre-packaged or frozen, but the convenience and time-saving elements are tradeoffs I don’t entirely mind.
If I have to peel and grate cassava roots, crack and milk coconut heads myself, I’d just as soon forget about making this cassava cake with custard topping. But by just heading to the freezer section for already-grated cassava and walking down the aisle for canned coconut milk, I can have it baking to sweet perfection in the oven in a matter of minutes.
What is Cassava Cake Made Of
Cassava cake in its basic form is made of grated cassava, coconut milk, and sugar which are combined into a batter, and then baked in the oven until set. The cooked cake is usually crowned with a choice of topping, ranging from a simple sprinkling of shredded cheese to a more elaborate custard made with eggs, condensed milk, and evaporated or coconut milk, and then baked a second time until golden.
As with most dishes, the recipe may vary depending on the cook and may include other additions to the batter mixture such as sweetened macapuno strips, young coconut meat, desiccated coconut, nata de coco or cheese.
How to Prepare Fresh Cassava
- Depending on the length, you might need to cut the tuber crosswise into halves or thirds to make peeling more manageable.
- With a sharp paring knife, slice the tuber lengthwise through the thick bark and carefully insert the thin end of the knife between the bark and the flesh to loosen. If the skin won’t peel easily, cut off the ends of the tuber and stand the root up on its end. With the knife, slice vertically down the sides of the root to peel the skin.
- Wash thoroughly and soak in a bowl of water until ready to grate to keep from discoloring.
- Grate the cassava using the small holes of a grater or run in a food processor into a fine texture.
- Using a cheesecloth, squeeze the grated cassava of the liquid which could be bitter. Please note that I use frozen cassava which I don’t drain when thawed; if using fresh, moisten with about 1/4 cup of water to yield the soft, moist texture of this recipe.
Tips on How to Make Cassava Cake with Custard Topping
- If using frozen grated cassava, thaw completely but DO NOT drain. If using freshly grated, which is usually squeezed dry, add about 1/4 cup water to moisten it. The recipe requires 16 ounces or two cups.
- I use a baking pan I bought in the Philippines which is 9 x 6-inches in size. If using a less-wide pan, adjust the cooking time as the cake will be thicker. Insert a toothpick in the center; if it comes out clean the cake is ready to top for the second baking.
- Aside from a few dark spots at the edges, you can see that the cake is mostly even in color. Make sure to use a light colored baking pan, so the bottom of the kalamay doesn’t darken too much through the twice-bake process. If the cake or the custard is browning too fast before fully set, tent with foil.
- Do not cover the cake until fully cooled as the escaping steam will cause water puddles to pool on top.
- Leftovers should keep in the fridge for up to 3 days. Cover tightly with plastic film to lock in freshness.
I first published this recipe in June 2013 and am updating it today with new photos and tips. I also modified the recipe and halved the ingredients to fit one pan (the previous measurements were for two pans).
Make this cassava cake today! I know taste is subjective and bragging is not allowed on the blog 🙂 but I have to say, this is one of, if not the best cassavang kalamay you’ll ever try. I used to sell it along with mini egg pies, and they were both my bestsellers!
The cassava layer is soft, moist, and delicious on its own but the flan topping takes it over the top. It’s like having two desserts in one bite!

Return to the oven and continue to bake for about 15 to 20 minutes until a toothpick inserted in the center of the flan comes out clean; if the top is browning too much, loosely tent with foil.

Lalaine,
My interest in Cassava is for low carbs and gluten free. The nutrition information does not list the serving size and the carbohydrate total is 78g. Would guess that some of that is from coconut?
The addition of the custard will make a delicious combination with fresh eggs from my hens.
Have you ever tried cassava with tapioca? I liked it with a little honey.
Anne says
Hello,
Can I use whole milk (fresh milk) instead of evaporated milk for the custard topping?
Kate I says
Hello po! Can I use 8×8 pan instead of 9×6? Will the proportions be the same?
Marie says
I tried making your cassava but without the flan topping . When its all done the entire thing was soft . . I even extended the time hoping cake will harden but still came out soft.Not sure what i did wrong . — Marie S

Mey says
Hi. I made this recipe but after 1 hr and 30 minutes, it’s still wet. I wonder why?
Melanie De Leon says
After several times of making this, I find that leaving out the 1/4 cup of sugar and macapuno is best, otherwise it’s too sweet that you can’t appreciate the cassava’s flavor. Also, clean up and cutting for sharing large portions is easier with a teflon pan. In place of foil, I use parchment paper atop for even baking, no brown spots. Thank you for another wonderful recipe. God bless!
Loreta Bourdeau says
This is one of the Filipino dessert that my Canadian husband liked. So I tried your recip and it was good! I don’t have a light colored brown pan so it darken the edges. I don’t mind eating it even when a little brown because stilp taste good. Btw I’m a big fan of your’s because your recipes are easy to follow.
Ann Say says
I found other recipes that include eggs/egg yolks in the cassava cake mixture. What’s the difference between the one with eggs and the one without? Your recipe looks so soft and yummy I’m going to try it
Joan says
Theh best cassava cake ive have ever made!
Melanie De Leon says
Yummy! I’ve made this a few times but the last time I made it, I used grated cassava from Vietnam because they didn’t have my usual Filipino brand and it turned out gooey, watery and lacking the cassava flavor.
Also, I double the custard because the canned ingredients come in that volume so I just use the whole can.
Melanie De Leon says
what if i double the amount of custard ingredients? will it turn out okay?
Amy says
Hi can i bake cassava cake with no mustard topping? Or i can i just mix the custard topping and bake altogether.?
Thank u and take care
