Dulce Leche Buttercream Cake



This is definitley a cake for the sweet tooth junkie. I love anything Dulce Leche (sweet milk) so I am always coming up with recipes that incorporate it. Last night my youngest son and his friends wanted something sweet so I went through the kitchen to see what I had on hand in ingredients and I came up with this. It is absolutely DELICIOUS!

How to Make Dulce Leche Buttercream Cake


  1. Remove label from sweetened condensed milk can. Boil entire can of milk on rapid constant boil for 1.5 hours. Set aside and allow to cool while preparing cake and frosting.
  2. Mix one tablespoon of cinnamon into yellow cake mix and bake cake in two separate cake pans according to box/recipe directions. Allow to cool on cooling rack.
  3. While waiting for cake and milk to cool prepare buttercream frosting:


    1 cup unsalted butter (2 sticks or 1/2 pound), softened (but not melted) Ideal texture should be like ice cream.

    3-4 cups confectioners (powdered) sugar, SIFTED

    1/4 teaspoon table salt

    1 tablespoon vanilla extract

    up to 4 tablespoons milk or heavy cream

    1.Beat butter for a few minutes with a mixer on medium speed. Add 3 cups of powdered sugar and turn your mixer on the lowest speed (so the sugar doesn’t blow everywhere) until the sugar has been incorporated with the butter. Increase mixer speed to medium and add vanilla extract, salt, and 2 tablespoons of milk/cream and beat for 3 minutes. If your frosting needs a more stiff consistency, add remaining sugar. If your frosting needs to be thinned out, add remaining milk 1 tablespoons at a time.
  4. Once cake and milk has cooled remove cake from pans and place one cake on plate. Cover cake with sweet milk. Allow to sit for 5 minutes. Add other cake on top. Butter with butter cream frosting.

    Note: I keep this cake in the refrigerator overnight if not serving immediately because of the milk and buttercream frosting. The cake and frosting will harden in the refrigerator. Allow cake to sit at room temperature before serving if you keep the cake in refrigerator overnight.
