Chocolate Flan Cake with Cake Mix

Modified: Mar 19, 2025 · Published: Jan 8, 2021 by Anna · This post may contain affiliate links · 56 Comments

Jump to Recipe

The New York Times recently published a recipe for Dulce de Leche Chocoflan aka Impossible Cake. I haven't tried their recipe, but it reminded me of the Chocolate Flan Cake with cake mix I posted years ago. And by that I mean many years ago, as you can tell by the pictures! All of the ingredients are from H.E.B. which is one thing I miss about Austin. Then again, I can't complain because here in Raleigh we have Publix and Wegmans.

Flan cake ingredients

Anyhow, I plan on making Chocolate Flan Cake again and will add a few more notes and tips when I do. For now, here's the recipe from way back. As the pictures show, the flan mixture gets poured over the cake mix. The two batters "magically" trade places while baking so the cake is on the bottom and the flan is on the top.

The end results is stunning! More stunning if you manage to get the cake out of the pan. Luckily, I didn't have any problems with this one. Using flour-added baking spray did the trick.

Not in the Mood for Chocolate Flan Cake?

If you like pumpkin cheesecake more than flan, there's also a Pumpkin Cheesecake Topped Bundt, and it does NOT call for cake mix. Like the Chocoflan from New York Times, It has a scratch chocolate base.

Servings 12

Ingredients
 

  • 11 ounces caramel topping softened or at room temp
  • 1 box chocolate cake mix, plus ingredients listed on box
  • 14 ounces sweetened condensed milk
  • 12 ounces evaporated milk
  • ½ cup milk
  • 8 ounces cream cheese -- softened
  • 1 teaspoon vanilla
  • 5 large eggs

Instructions
 

  • Preheat oven to 350 degrees F. Spray a 12-cup bundt pan with flour-added cooking spray or grease the pan with shortening and dust with flour.
  • Pour the caramel topping into the greased and floured Bundt pan.
  • Prepare cake mix according to package directions. Pour the cake batter into the cake pan over the caramel topping.
  • Make the flan. Pour condensed, evaporated and fresh milks into a blender. Add softened cream cheese, vanilla and eggs and blend until smooth. Pour the flan mixture very slowly over the cake batter.
  • Spray a sheet of aluminum foil with cooking spray (or just use nonstick foil) and cover the pan TIGHTLY with the foil. Covering tightly is very important. Set the Bundt pan into a large pan (such as a roasting pan) and set on the oven rack.
  • Carefully pour hot water into the larger pan to a depth of 2 inches (the Bundt pan will be sitting in 2 inches of water). Bake for two hours.
  • After two hours, remove cake from water and allow to cool for 15 minutes. Peel off the aluminum foil. Invert cake onto a large plate with rim. The caramel topping should flow down the sides. Cool completely then refrigerate.

    Hi Sammi,
    Thanks so much for making it!! I just woke up to read this and you've already made my day. I haven't made it in a (very long!) while and need to, so it's great to have a review from another baker.

    I really like this recipe! It's very simple and easy to follow. Only thing was that when I made it my choco flan had more cake than actual flan so the next time I would want to use only half of the cake batter. I just made another one today with vanilla cake instead but again I forgot to only put half the cake batter lol! I hope it tastes just as good as it did with the chocolate cake. 🙂

    Made this today. My bundt pan held just over 10 cups of liquid, so I removed 3/4 cup of the choc cake mix, after it was prepared but before I poured it into the bundt pan. Followed all the other directions (actually used skim milk, because that is all I had). Baked for 2 hours. Cooled it about 45 minutes, then put it in fridge for one hour before serving. It was Awesome! Looked so pretty, too! Thanks for the fun recipe. It is a new family favorite.

    May 03, 2012 at 9:32 pm

    Just FYI, don't use the Pampered Chef springform bundt cake pan!! You end up with just chocolate cake! The custardy flan part leaked out and cooked itself in the water. 🙁 Will definitely try again though because it smells amazing and the cake part turned out pretty good.

    Hi Anna, your flan cake looks beautiful and delicious. I make Leche Flan Cake (that's how we call it) from scratch using chiffon cake and the procedure is different from yours. I got it from another blog and it's one of our favorite desserts.

    if u have problems with the flan u can buy a flan mix that u just add the milk , there is a different brands i use , is royal flan or jell-o . its really smooth and less work ..!

    I love love this cake. The cake is rather moist and the flan it smooth and creamy. It's a long process from start to finish and then to eating it but it's so worth it. I have made this cake 3 times and will make it again next week for my mom's bday, who has never had flan. I know she will like it though.

    You can also make this cake without the cream cheese. In a blender, add 1 can of evaporated milk, 1 can of sweet condensed milk, 1 teaspoon of vanilla, 6 eggs, 2 spoonfuls of sugar. Blend until incorporated, then add slowly to the cake mixture. Bake for 1 1/2 hours with foil. Also it's better if you can find cajeta instead of the caramel because the consistancy is better, or use a can of dulce de leche. This flan recipe is better than the above....I don't care for the cream cheese flan...

  25. Anna says

    February 22, 2010 at 7:25 am

    Hi!

    Sorry your first one didn't turn out. I am not an expert on flan or custard making and I only made this cake a couple of times, but I'm pretty sure the foil is to hold in the moist heat so that the custard will kind of steam rather than dry out?

    Before you start the second cake, you might want to check some other bloggers renditions of this cake and they might have better advice for you.

    Hi. Baked this last night and it turned out less than expected, mostly because my oven temp crept too high. I'm making another one this morning since I'm cooking for friends tonight. What's the reason for the aluminum foil covering the pan? And why such a long cook time? (novice guy-cook here)

    Hi Melanie,

    My first thought was that you switched Bundt pans, but you said you didn't do anything differently so I'm stumped! I haven't made this one in a while, but it's become quite a popular cake so you might want to look around for some clues.

    The other thing could be your oven. Have you noticed it baking things slower lately? Maybe it's just not getting as hot as it should be? For a while, my old oven was overcooking everything. I bought an oven thermometer and found it was about 40 degrees off!

    I have made 4 attempts to make this cake. 2 times it was great, but 2 times the cake did not set up properly during baking and was a gooey mess. Once, when this happened, I served it as a type of "cake pudding," because I didn't have time to make anything else. I didn't do anything different the 4 times I made it. Any thoughts?

    HI, i just wanted to say that i have tried this reciepe before but with german chocolate cake and with the carmel and coconut and pecan on top of the flan.You must eat it cold. VERY VERY EXCELLENT!!!

    Hi Anna
    I just made a version of this cake for Canada Day (July 1st)and we loved it. The recipe that I used omitted the fresh milk and it used only 3 eggs but otherwise was the same. It overflowed my Bundt pan but since it was in a water bath it didn't really matter too much but the next time I will remove some of the batter and the flan to a separate smaller pan-sort of like a taster cake. I liked the ideas of using different flavors of flan and cake that other commentators mentioned. I agree Anna-it's hard to beat a good cheesecake but this cake has a WOW factor going for it that is a big payoff for a relatively simple preparation.

  33. Anna says

    June 23, 2009 at 5:35 pm

    Just got a comment from someone who didn't like this cake. Not sure if the person actually tried it, but she said she did and that this flan was not authentic because of the cream cheese. Here's a tip. This cake is a fun, gimmicky cake. If you're looking for authentic flan, try a real authentic flan recipe.

  34. vanessa says

    May 24, 2009 at 9:48 pm

    i want to try this recipe but with another chocolate cake recipe. the cake recipe i want to use is poured into two 9 inch round cake pans baked at 350 degrees for 35 minutes....so do i still bake it at 350 for 2 hours or do i need to adjust the time+degrees? sorry im a beginner baker!

    I just recently stumbled across your blog and am amazed by all of the wonderfully yummy recipes!

    This cake is great for entertaining--it is easy and the end result is very impressive! I made mine with Banana cake and drizzled on some extra caramel! It smells, looks and tastes FANTASTIC!

    Thanks!

    I make chocolate Flan all the time and I have never hear of putting a cake into it. I'll try it and get back with you. My husband makes the regulate Flan. But since I have tried my hand at it, chocolate is the only one for us. But I would say the carmel syrup you speak of is not as sweet as real sugar, so to get the sweetness you should try it with the real sugar glazing.

    August 20, 2008 at 10:38 pm

    add the cajeta inside the pan before you bake it but make sure you warm it up in the microwave for 30 seconds then add it to the pan. i sprinkle some choped pecans after i inverted.

    Hi Lorna,

    The flan mixture sinks to the bottom, thus ending up on the top when you flip the cake.

  40. Lorna says

    June 16, 2008 at 10:19 am

    if i have to pour the cake mixture first how come the flan mixture is on top of the cake mixture that is in the pics above?

  41. Brittany says

    May 01, 2008 at 10:43 am

    This looks great i havent cut into it yet but i was just going to say if you want instead of using carmel you can go the mexican way and use cajeta it has a little more of a creamy flavor and instead of evaporated and condensed milk you can use la lechera and evaported just to make it more origial hope its good oh and just wondering do put the cajeta{carmel} straight into the bundt pan or into a seperate? please respond fast!!!!

    My results using SCRATCH cake: EXCELLENT!
    It was served at a holiday party and 4 people requested the recipe.

    However, My favorite cake recipe uses 1 & 3/4C Flour, 3/4C Cocoa and 1 & 3/4C Milk ... which made too much batter for the pan. So, if you do use a scratch recipe; I would say use one with smaller quantities of flour (and cocoa) and milk, use a larger Bundt pan or, as I did, use less of the cake batter.

  43. Muffy says

    December 09, 2007 at 3:41 am

    Has anyone tried this with homemade cake batter? What were the results?

    I don't use box mixes, and was wondering if anyone had done the scratch route yet. If not, I guess I will have to be the guinea pig and let you all know!

  44. Anna says

    November 18, 2007 at 10:41 pm

    I'm glad you all liked it. I haven't made this one in a while, so thanks for bringing it to my attention. It's a great holiday cake.

  45. Terri says

    November 18, 2007 at 9:42 pm

    This is THE BEST flan cake!! I've made it for family and friends, and everyone asks for it at parties and holidays. It gets easier the more you make it. I use an old original Bundt cake pan, ways a ton. But it has the room for all the ingredients. You have to slowly pour in the liguid onto the cake mix.

    Leslie,

    Thanks for pointing that out. I have changed the instructions to say "blender" since food processors tend to link.

  48. Leslie says

    November 07, 2006 at 2:26 pm

    I had trouble with this recipe. Seemed like the chocolate cake batter substantially filled the bundt pan, but as it turns out had room for the flan because it leaked out from my Cuisinart deluxe food processor. (huge mess) Finished the flan in the blender. Unless this is fabulous can't see making it again. Leslie

    I have Marta's pumpkin flan recipe, if you want it, drop me an email. It's really, really good. I've made it for Thanksgiving a couple of times.

    But this is The Perfect Flan.

  53. Anna says

    September 23, 2006 at 4:24 pm

    I was hoping this cake would make me like flan. It's not a dessert I hate, just something I don't find as appealing as cheesecake.

    At room temperature, this flan was kind of lumpy. After being chilled, it smoothed out quite a bit and had a much better texture. It's not very sweet, so you may want to add some more caramel sauce.

    In the meantime, I'd be curious to hear how a different but similar flan recipe works out. There's a prize winning recipe in Southern Living which is similar, however it uses extra yolks, sugar and is strained. It might make for a creamier, velvetier flan. Here's the link if anyone wants to experiment.

    http://www.foodnetwork.com/food/recipes/recipe/0,1977,FOOD_9936_25696,00.html

    Obviously, you'd skip the sugar burning part and just use the method this woman uses for flan -- separating eggs, straining, etc.

    I think maybe a pumpkin flan or a chai-spiced flan would be interesting too.
