Sweetened Condensed Milk Chocolate Buttercream Frosting

"I love to bake cakes and cupcakes. Sometimes I get bored with traditional buttercream icing. So I experimented a little bit and made a very delicious and popular icing that was made with sweetened condensed milk. My Vanilla Sweetened Condensed Milk Buttercream Frosting recipe has been a huge hit on my blog and with people that have tasted the recipe. And I started to get some requests about how this could be a Sweetened Condensed Milk Chocolate Buttercream Icing."
