Step 1

Preheat the oven to 350°F.In a small saucepan over medium-low heat, add the sugar and melt until fully dissolved, keeping a close eye to prevent burning. Swirl the pan gently as the sugar starts to melt. Once the sugar turns a rich golden color, remove it from the heat.

Step 2

Quickly pour the melted sugar into the cake pan, spreading it evenly all around the bottom and sides of the pan before it hardens. Set it aside to cool.

Step 3

In a blender, combine the sweetened condensed milk, evaporated milk, eggs and vanilla extract until smooth. Pour the mix over the caramel sauce.

Step 4

In a large bowl, use a mixer to prepare the cake mix following the package instructions. Carefully pour the cake batter over the flan. DO NOT STIR THEM TOGETHER.

Step 5

Cover the cake with aluminum foil.

Step 6

Add the cake pan to a larger pan and fill the larger pan with hot water so that the water comes halfway up the sides of the flan cake pan.

Step 7

Carefully add the pans to the oven and bake for 1 hour and then check for doneness by inserting a toothpick or thin knife into the center. If it comes out clean the flan cake is done. Otherwise cook for an additional 20-30 minutes.Once done, remove the cake pan from the water bath and set aside to cool completely. Once cool, refrigerate the flan for a few hours or better overnight.

Step 8

To unmold, run a knife around the edges of the pan to loosen the flan cake a little bit. Then place a serving platter over the flan cake and holding it firmly, flip the plate and cake over, right side up. Cut the cake into slices and serve. Enjoy!
