Flan Cake

Flan Cake is easy and so delicious! A combination of cake, flan, and caramel sauce all in one pan!
Flan cake is one of those things that I arrived at in a very round-about way:

  • I had a yummy dessert at Alt Summit in SLC in January that was labeled “flan,” only it wasn’t flan, it was cake, pudding, and whipped cream (tasty, just not flan)…
  • I did some research to see where in the world they would have gotten the idea to call that flan…
  • It turns out that there’s a Puerto Rican dessert called flancocho that has a layer of cake topped with a layer of flan topped with a layer of caramel sauce…
  • I decided that flancocho looked darn tasty, and even if it bore no resemblance to the “flan” from Alt Summit, I was going to make some and see if it tasted as good as it looked…
  • Most flancocho recipes use a boxed yellow cake mix for the cake layer (no!), and have quite a hefty dose of cream cheese in the flan layer (what?!), so I would need to search more intensely…
  • It’s easier to find from-scratch Chocoflan recipes, which have a layer of chocolate cake topped with flan and caramel sauce…
  • Only I had already made up my mind to have a vanilla cake layer, so why oh why was I having such a difficult time with this…
  • After 4 months of not being able to figure out how to solve this problem, I finally hit upon a not-exactly-rocket-science solution–adapt a dang Chocoflan recipe to make the cake layer vanilla instead of chocolate…
  • Boom. Flan cake.
Should that have taken me 4 months? Probably not. Were the results of all my research and fretting sweet, delicious, and well worth it? Absolutely.

Flan Cake is easy and so delicious! A combination of cake, flan, and caramel sauce all in one pan.
Recipe type: Dessert
Serves: 16
for the caramel layer:
  • 1 cup caramel sauce (store-bought is fine)
for the cake layer:
  • 10 Tablespoons butter, plus more for greasing the pan
  • 1 cup sugar
  • 1 egg
  • 2 cups all-purpose flour, plus more for dusting the pan
  • 2 Tablespoons cornstarch
  • ¾ teaspoon baking powder
  • ¾ teaspoon baking soda
  • 1¼ cups whole milk
for the flan layer:
  • 1 12-oz can evaporated milk
  • 1 14-oz can sweetened condensed milk
  • 4 eggs
  • 1 teaspoon vanilla
  • sweetened whipped cream for serving
  1. Preheat the oven to 350°F and put a kettle of water on to boil. Also, find a big roasting pan (big enough for a 9x13" pan to sit inside of) and set it aside.
  2. Butter a 9x13" pan generously and dust it with flour. Turn the pan upside-down over the kitchen sink and shake out the excess flour.
  3. Pour caramel sauce evenly over the bottom of the pan. If the caramel sauce doesn't want to spread itself out, gently tip the pan back and forth until the caramel covers the bottom of the entire pan evenly; set pan aside.
  4. Using a stand mixer or hand mixer, cream softened butter and sugar until fluffy. Add egg, and beat, scraping down the sides of the bowl as necessary. In a medium bowl, combine flour, corn starch, baking powder, and baking soda. Add ⅓ of the flour mixture to the butter and sugar mixture, beating until just combined. Add ½ of the milk, and beat until combined. Continue adding flour mixture and milk until all ingredients have been added. Turn the mixer up to medium speed and beat 30 seconds. Carefully spread the cake batter over the caramel sauce in the pan.
  5. In a blender, combine all flan ingredients until smooth. Pour the liquid very gently and evenly over the cake batter.
  6. Put your big roasting pan in the oven, set the 9x13" pan inside it, and pour enough boiling water into the roasting pan to come about half-way up the sides of the cake pan. Be careful not to pour hot water into the cake pan!
  7. Bake for about 55 minutes, until the cake has begun to pull away from the sides of the pan. A knife inserted in the center should come out clean. It's OK if the knife comes out wet, as long as the liquid is completely clear.
  8. Allow the flan cake to cool in it's pan for about 1 hour, then run a knife all the way around the edges. Take a rimmed baking sheet, place it face down on top of the cake pan, grip both very tightly, and flip the whole contraption over. Set it on the counter and gently remove the cake pan. You should have cake on the bottom, flan next, and caramel sauce on top! Allow it to finish cooling before serving. You probably don't want to serve it to guests straight off the cookie sheet, so you might want to plate individual pieces first. And you'll definitely want to top each piece with lots of sweetened whipped cream! If there are any pieces leftover, cover them tightly with plastic wrap and refrigerate.

  1. Ever since I was a little girl my mom always made a cake that’s very similar. For the cake she uses an Angel food cake in a bunt pan and instead of cream cheese in tghe flan we use carnation milk.
    Back home in the Philippines we call the custard Leche Flan and its a common recipe in every household.

  2. How can you have cake at the bottom, flan next and caramel on top when you flip it over when during preparation you put the cake batter first on the caramel sauce then the flan last. This recipe looks so delicious but I’m a little confused…

    1. So, that is the magic of this cake! As the cake bakes, the flan and cake switch places, so the cake ends up on top with the flan underneath it. So when you flip it all over to let it cool, you end up with cake on the bottom, then flan, then caramel sauce! It’s magic!!

  3. Hi Lulu, my daughter and I are making this today to take to a Mexican themed party and are excited to try it. Just wanted to let you know that the 2Tbl of cornstarch in the ingredients list isn’t used in the instructions in case you wanted to revise.

    Thanks for the recipe! I’ll let you know how it turns out!

  4. I have to say, I do love a great flan. And my favorite is the one that has cream cheese (which would be a cheesecake flan). Now, this one looks amazing…but I a bit bitter that NONE of all the puerto rican friends I grew up with shared this deliciousness with me. Those sneaky friends. 🙂

  5. My husband works with a Mexican woman, Lupe’ Maria, and she is the most awesome cook! Her recipe calls for cream cheese in the flan but I didn’t know it was “cheesecake” flan. Sometimes when I want it really rich I use 2 cans of condensed milk and eliminate the evaporated. Extra yummy and thick!

  6. This was my first attempt at flan cake and it turned out very good! I used an oven thermometer to make sure the oven temp was accurate, and it baked beautifully. I followed everything in the recipe with the exception of the caramel.(I made it homemade.) Thank you for sharing this delicious recipe.

  7. Finally!! A cake flan recipe with a cake made from scratch!! I’ve been searching and searching but all the recipes are made with boxed cake mix. I can hardly wait to try it. I’m making it for my brother’s 14th birthday on the 15th of this monyh

    1. I’ve never tried it! I know I’ve seen chocolate flan cakes baked in bundt pans. Perhaps you could check the baking time and temp on one of those just for reference. Best of luck!

      1. Yes, most Flan Cake recipes use a Bundt pan. I’m wondering about using two 9X9 pans instead ( for two different gatherings on the same day
