It's a good thing this wasn't for anyone in my house because I would eat the whole thing myself. It's chocolate cake with dulce de leche filling and dulce de leche flavored buttercream icing. I have never made dulce de leche before, but it was super easy. You just boil a can of sweetened condensed milk for a couple of hours making sure the keep the can completely covered with water and you end up with the yummiest treat EVER!
For the dulce de leche buttercream: Use your favorite buttercream icing recipe and add 1/4 cup of dulce for every 1cup of buttercream. Mix until well blended, making sure there are no lumps.
To assemble: Fill the cake with strait dulce de leche, but first pipe a dam of icing so it doesn't ooze out the sides. Frost the cake with the dulce buttercream. Use some buttercream, tinted the same color green as the leaves, to pipe the stems. Add the sunflowers, using extra icing if needed to get them to stick to the side of the cake, and the leaves. I did mine at slightly varying heights around the cake. To finish, I piped a simple bead border around the bottom of the cake and piped the message on the top with buttercream.
Because the most time consuming part of making the cake is done in advance, it goes together really quickly the day of. I would love to see pictures if you try it!
