Easy Brazo de Mercedes

We have this family friend who makes the best Brazo de Mercedes. I only tasted it once as a kid and I never forgot it. During the recent monsoon rains, we evacuated at their house and so we made one for fun. :) I never thought that it would be so easy!

INGREDIENTS:(Makes 2)
8 small eggs or 7 medium eggs
1 teaspoon of Cream of Tartar
1 can of Condensed Milk
1/4 of the biggest butter (we used Dari Creme Classic)
1 cup sugar
1 teaspoon of Vanilla (optional) -- we didn't add vanilla but I bet it'll be yummier with this
2 Parchment Paper/Wax Paper

STEPS:
-Separate egg white from yolk

-Mix the egg yolks, condensed milk, and butter using a double boiler (i.e., there's boiling water beneath the pot since you can't cook the mixture directly on fire)
-Don't stop stirring until the mixture becomes thick (you'll know it's ready when you scoop the mixture and it slowly falls from the spoon)

-After cooking the yellow filling, whip your egg whites and cream of tartar
-Add sugar gradually
-Add vanilla

-Prepare the cookie sheet by spreading small amounts of butter and then lining it with wax or parchment paper
-Spread the white mixture (meringue) on your cookie sheet
-Use oven or toaster to heat the top until it becomes golden brown (it's better to just hold it because if you leave the meringue inside the oven, the whole thing might get burned)

-When you get the desired "cook" of the meringue, flip it over so that you can spread the yellow filling next
-Spread the yellow filling (don't put it on the middle or too much on the side)
-Roll the meringue carefully
-Sprinkle sugar (granulated or confectioners sugar) on top
-Place inside ref first to cool before eating

P.S. We didn't use all the eggs so this little one right here got all angry at us :)) (Egg drawing by Angela)

Thanks again to the Robles family! :) This is such an easy dessert to make!
