You know it’s going to be a good week when samoas are involved.  If you don’t believe me, I have 25 samoa recipes just waiting to prove my point. That means plenty of toasted coconut, caramel, chocolate and more chocolate. The Girl Scouts are out and about on street slinging those wonderfully addicting cookies and I am sitting back trying to resist the urge to eat an entire box.

The only way I can avoid eating a whole box is by using them in a dessert. This Sinful Samoa Cake could not be any more decadent. You start with a basic chocolate cake, then layer in coconut caramel cream cheese. The cake is frosted with a rich, fudgy dark chocolate buttercream. I couldn’t think of a better way to top this cake then with a pile of toasted coconut slathered in more chocolate and caramel.

I didn’t originally set to out to make a samoa cake; it just sort of happened. I am SO glad that it did. I almost couldn’t wait long enough to get through my photo shoot to take a bite.

Let’s break it down. The chocolate cake recipe should be your favorite chocolate cake. I didn’t do anything special, I just used a box of my favorite cake mix and made some alternations. When I do bake from scratch, I always make my Moist Chocolate Cake Recipe. It’s light and fluffy and seriously THE BEST!

I really wanted to incorporate a “cheesecake” element into this cake, so I decided on a caramel cream cheese filling. The softer the cream cheese, the easier it is to spread on the cake. I wanted to add a bit of texture to the cheesecake, so I mixed in a cup of toasted coconut.

The fudgy dark chocolate buttercream is made with Hershey’s Special Dark Cocoa Powder. Now you can use any cocoa powder of course, but I always prefer dark chocolate. It is sweetened so you don’t get such a bitter taste. You could definitely dig into that buttercream with a spoon.

While the frosting is still soft, start to pile the toasted coconut on top of the cake. Save a little bit to garnish at the end. Then I drizzled this with caramel sauce and fudge sauce. I keep jars of caramel and hot fudge sauce in my refrigerator. You should heat up the hot fudge so it’s warm but not too hot and then drizzle over the cake.

Since there is a layer of cream cheese, this cake should be kept refrigerated. If you try to cut it straight out of the refrigerator, the frosting will be firm. So I like to let it sit on the counter for about a half hour before cutting into it. It’s hard to wait but I promise it is worth it.
