Sweet sandwiches anyone? Well, these delicious chocolate cakes with marshmallow filling will certainly satisfy your cravings. They did mine.

When I whipped them up, my intention was to make whoopie pies which are a huge fave of mine. Technically I guess these could still be called whoopie pies, but I couldn’t bring myself to name them that since the tops of my cakes weren’t smooth like the ones I associate with whoopie pies or “gobs” like they’re also called in some states.

Anyway, short story shorter… I’m going with cakewiches. Chocolate cakewiches because smooth or not, these were so good I had to share.

Start out with simple ingredients to make your batter.

Then use a 2 to 2-1/2 inch scoop for equally sized cakes. Mine was 2-1/4 inches wide.

The batter will spread so give them plenty of room. I’d go with about 3 inches in between to be on the safe side. Just bake them in multiple batches.

You’ll end up with 12-14 cakes that are about 3-1/2 inches in diameter.

You can also use a smaller scoop and end up with more, but I like a big handheld size cakewich.

Once baked and cooled, transfer them all to a large baking sheet to assemble.

Make the marshmallow filling and pipe on a thick layer using an Ateco #807 decorating tip.


Sandwich those babies together. Just be gentle when pressing so you don’t break the cakes. They are delish, but also delicate.

I wish (whoopie pies) or cakewiches like these, were sold in more bakeries. I would absolutely buy them whenever I came across them.

Buy them or bake them, I dream of sinking my teeth into them. Just. Like. This. OMG! so good.
