Chocolate Flan Cake is Mexican dessert also known as Chocoflan or Impossible Cake – it’s one of the most delicious desserts consisting of a thick velvety flan on top of a rich brownie like chocolate cake with a caramel topping. When you put the cake together, you pour the chocolate cake batter on the bottom of the pan and the flan mixture goes on top, when it’s done baking, the two layers switch places, so this “magic” is how it got the name Impossible Cake – seriously the coolest cake around.
I tried looking for a pan that fit into the Instant Pot in several stores, but I couldn’t find one small enough – so I ended up ordering a 7 Inch Bundt Pan on Amazon that fits in the 6 Qt and 8 Qt Instant Pot (link here) and it works perfectly for this recipe.

If you use your Instant Pot on the counter under your cabinets, this is an awesome accessory that diverts the steam downward and away from your cabinets (purchase here)

Looks delish! If I made this before work and left it refrigerated in the pan all day–instead of just two hours–would it still work?

Hi Victoria, yes you could definitely refrigerate it all day and it would still be amazing!

Looks Amazing! Will I be able to make this without using eggs? Is there a substitute for eggs in this recipe?

Hi Janani, sorry I have never made flan or cake without eggs so I don’t know how you would substitute it in this recipe.

I made this last night, looks like your picture and tastes pretty darn good. The only thing I was unsure of (after the cake was in the IP while re-reading the recipe) was the amount of sweetened condensed milk. I converted the can I bought here in Canada (300 ml) to fluid ounces and it was less than the 14 ounces you call for in the recipe. I was a little anxious, hoping it would set up and it did, whew 🙂

Hi Elisabeth, I’m glad the cake turned out well for you! I think all sweetened condensed milk cans are the same size, it’s 14oz in weight and about 1⅓ Cups measured which is the same as 300ml.

Thank you for this fabulous recipe! I had never tasted flan before, so after making this I made flan. However, your recipe combines the flan with chocolate cake, which seem to even improve with age in the refrigerator, rather than the cake part drying out. So, wonderful recipe! MY QUESTION: my granddaughters prefers dairy free recipes, so would it be possible to substitute rich coconut milk (canned) for the half& half cream? I could substitute Earth balance for the butter, & maybe just use the small amount of cream cheese.

Hi Joanne, I’m so glad you enjoyed there chocolate flan cake! Yes you can substitute coconut milk for the half and half in the chocolate cake recipe. Are you trying to make the flan dairy free as well?

Hi, can I make this in a 7″ springform pan instead of a bundt pan? Would I have to adjust the cooking time?
Van
May 23, 2018 at 6:54 am
Hi Susan, I have tried making this in a 7 inch springform pan & it doesn’t work well for this recipe, the cake cooks unevenly and you have to add more cooking time which dries out the out edge of the cake & over cooks the flan. It’s best to use a bundt pan.

I’m confused: Your list of ingredients call for a teaspoon of butter to cost the bundt pan yet the directions state use a stick of butter. Please advise.
Thanks
Van

Hi Deb, you only need about a teaspoon of butter to coat your pan, I just meant you could use a stick to do the coating, sorry for the confusing wording.

Hi, this recipe looks amazing and I’m eager to try it. I have a bundt cake pan from Amazon that says it’s 6-cup https://smile.amazon.com/gp/product/B00IOYJ186/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1. I’m wondering if I could use my pan for this recipe. This pan *just*fits* in my 6-qt Instant Pot. Could you possibly measure your pan and tell me how many cups of water it holds when filled to the rim? Thanks! Barbara
Van
June 5, 2018 at 4:34 pm
Hi Barbara, the bundt pan I used holds 5.5 Cups of liquid, so if you have a 6 cup bundt pan, that would work great for this recipe. Hope you enjoy it!

Awesome recipe! My husband loves chocolate cake and flan so this was the perfect recipe for him.

I just took this out.
Some cake spilled out to bottom of insert.
The foil was puffed up and cake doesn’t look cooked completely. Should I have plugged hole? I’m wondering if I should put it back in and save this desert
Van
July 9, 2018 at 9:11 pm
Hi Sheila, what pan did you use? Was it the same one that was posted with my recipe? You don’t need to plug the hole. Did you test the doness of the cake using a toothpick (it should come out clean) if you see wet batter on the toothpick you can put it back in for another 5 minutes.
Sheila
July 9, 2018 at 9:16 pm
Yes it was the same pan I will try that.
Thank you

This cake looks great! Could I use a box cake or brownie mix instead of making the chocolate cake from scratch? Thanks … gk
Van
September 20, 2018 at 10:16 am
Thanks Gina! You can use any chocolate cake box mix if you want, you only need to use 1/3 of the box though. Hope you enjoy it!

I don’t buy all purpose flour, I use self rising.
Could I use that and omit the baking soda and powder?
Van
September 27, 2018 at 8:21 am
Hi Bonnie, you can omit the baking powder in the recipe, but you still need to add the baking soda. Hope you enjoy it!

Please help! I tried your recipe twice and I don’t know what I’m doing wrong. The flan part mixes in with the cake in the Instant Pot. Almost the consistency of bread pudding instead of becoming it’s own separate layer at the top. Any suggestions?
Van

Hi Julie, are you making any substitutions and are you using a blender to blend the flan ingredients very well?
Julia
January 29, 2019 at 4:21 pm
I’m a little confused…You said to add the caramel to the bottom, then add the chocolate cake batter (which would be on top of the caramel) and then add the flan mixture. In that case, when you flip the cake out of the pan the chocolate would be on the top. Did you flip the cake over? Is there any caramel sauce on the flan part of the cake?
Van
January 29, 2019 at 8:18 pm
Hi Julia, if you read the little write up about this cake above the recipe, it explains why you put the flan and cake batter in that order – they switch places when you bake it – pretty cool huh? Hope you enjoy!
Lisa
June 29, 2019 at 4:45 pm
I followed your recipe exactly, letting it cool in the pan for an hour. I flipped it over onto a plate, however it is stuck in the pan. I thoroughly greased the entire inside with butter. Any thoughts on why this happened?
Lisa
June 29, 2019 at 5:03 pm
I was able to use a plastic knife to gradually loosen the cake from the pan. With all of the butter used, I thought it would slide right out. Would a non-stick spray have been a better option?
Van
July 2, 2019 at 9:42 am
Hi Lisa, which pan did you use? What caramel did you use? I haven’t tried a non-stick spray since I’ve never had an issue using butter – but give it a try next time and let me know if it helps.

Just rec’d the bundt pan in the mail. Can’t wait to make this.

I‘d like to try this now but don’t have the caramel sauce. Can I just make the caramel on stovetop with sugar and water, like for regular flan?
Van

Hello, yes that will work too, hope you enjoy it!

Just got a 6 inch bundt pan but it is too big for my 3 qt. Thought it would be perfect as I use a 6 inch springform for cheesecake. Can I bake this cake in an oven? I’m not going to buy a bigger instant pot or return pan. Thanks!
Van
July 19, 2020 at 3:24 pm
Hi Sammye, yes you can bake this in an oven. Pre-heat your oven to 350F. You’ll need a larger baking dish that can fit the bundt pan in, place it in the oven and fill it with an inch of boiling water and place the bundt pan into the dish. Bake for about 40-50 Minutes, the surface of the cake should be firm and a toothpick inserted should come out clean.

I used Hershey’s Special Dark cocoa powder and the cake part came out really dense, do I need to use the regular cocoa powder for a lighter or fluffier cake texture?
Van
July 22, 2020 at 4:10 pm
Hi Lena, the cocoa powder isn’t the reason the cake it dense – it’s from cooking it in the Instant Pot. If you read the description above the recipe I mention that it’s like a brownie.

made this as directed. It came out fabulous! Oddly my caramel sauce repositioned itself between the other two layers, but it works great there between the flan and the cake. Using the IP is so much better than the long bake recommended for the “regular” versions of this dessert, and the size of this recipe is perfect. Thank you so much.

I’m confused. Your directions say to put the flan ON TOP of the chocolate cake when putting it in the bundt pan yet the photo shows the flan as going in first, on top of the caramel. It doesn’t seem possible that the flan sinks below the chocolate cake while baking but in order to have the finished product look like the photo it would have to change places with the flan. Help, please
Van

Hi Jan, just read the short description above the recipe, I actually talk about this…

Anxious to try this recipe – I have pre-made dulce leleche sauce (made from condensed milk in IP) and wondering can I use that in the flan, rather then the condensed milk, if maybe I dilute a bit with some more 1/2 & 1/2 ?
Van
January 27, 2022 at 5:48 pm
Yes, that would work fine for the caramel.
