Flan Imposible

Directions

1. 1
   Preheat the oven to 375F.
2. 2
   Lightly grease the bottom and sides of an 8-inch cake pan.
3. 3
   Pour the cajeta over the bottom and sides of the cake pan using a brush or the back of a spoon (you can heat the cajeta very slightly in the microwave so that it is easier to spread).
4. 4
   TO MAKE THE CAKE, combine the sugar, flour, cocoa powder, baking soda, baking powder, and salt in a large bowl and whisk until well blended.
5. 5
   In a separate bowl, whisk together the buttermilk, vegetable oil, egg, and vanilla.
6. 6
   Add to the flour mixture, whisking until thoroughly combined.
7. 7
   Pour the cake batter into the pan and set aside.
8. 8
   TO MAKE THE FLAN, combine the evaporated milk, condensed milk, eggs, vanilla, and salt in a blender and blend until there are no visible lumps.
9. 9
   Pour gently over the cake batter.
10. 10
    Cover loosely with foil, place in a large baking dish, and fill the baking dish with hot water so that it comes halfway up the sides.
11. 11
    Bake until a toothpick inserted into the center comes out clean, about 50 minutes.
12. 12
    Remove the cake pan from the baking dish and allow to cool for at least 4 hours or refrigerate overnight.
13. 13
    To unmold, lightly pass a warm knife around the edge, place a plate or dish on top, and carefully but rapidly flip over.
14. 14
    Garnish with the toasted nuts.
15. 15
    Serve cold or at room temperature.
