To begin we are making a caramel sauce in a saucepan over medium-high heat add in half a cup of water followed by one cup of sugar

bring it to a boil and cook until it turns light brown make sure that the caramel sauce does not burn because if it does burn it's going to taste pretty bitter

once it turns brown quickly remove it from the heat and add it to the bottom of your cake pan

preheat your oven to 400 degrees F.

Now in a mixing bowl add in four large eggs a 12-ounce can of evaporated milk a 14-ounce can of sweetened condensed milk

one tablespoon of pure vanilla extract oh and be sure to use pure vanilla extract we don't do imitation thank you now whisk until thoroughly combined

then pour it inside your cake pan the caramel sauce would have cooled off by now but that's okay no worries

Transfer the cake pan to a large baking dish fill up the baking dish with cold water at least half the way full then transfer to the center of your preheated oven at 400 degrees for 30 minutes.

Now in a mixing bowl sift 1 cup of all-purpose flour 1 cup of sugar, 1/ 3 of a cup of cornstarch, 1 teaspoon of baking soda, 1 teaspoon of baking powder, 1 teaspoon of salt, 1/ 3 of a cup of Hershey's cocoa powder. Whisk the dry ingredients until thoroughly combined. Then add 3 /4 a cup of milk, 1 cup vegetable oil, and one tablespoon of pure vanilla extract.

With a hand mixer on low speed, go ahead and start mixing, and as we are mixing add two large eggs one at a time.

continue mixing on medium speed until thoroughly combined

and after 30 minutes get the cake pan out of the oven

then gently pour the cake batter over the flan

cover the cake pan with aluminum foil and reduce the temperature of your oven to 350 degrees now bake at 350 degrees for one hour

After one hour take out the oven, and remove the aluminum foil. Toothpick test if it comes out clean it means that it's done. Let it cool off for at least two hours before serving. And after it has cooled off place a plate on top of the cake pan and flip it over.

Enjoy, buen provecho!
