INSTRUCTIONS:

1st Step

To make the cake batter, just follow the steps outlined in the package. Put the batter in a 9×13-inch baking dish that has been buttered. Bake as directed on the packet. Don’t touch the cake until it’s totally cooled.

2nd Step

Make holes all over the top of the cooled cake with the handle of a wooden spoon or something similar. Verify that the holes reach the base of the object.

3rd Step

Combine the egg yolks, sugar, and cornstarch in a medium saucepan and stir until smooth. While whisking, slowly pour in the milk.

4th Step

Cook the mixture over medium heat until it thickens and comes to a low boil, stirring often. Turn off the heat and add the vanilla. Please wait a few minutes until the custard cools.
