I had some leftover pistachio butter-cream from making some pistachio macarons. I don't like to eat butter-creams in big doses, like a huge butter-cream cake. So I decided to make something small. Petit Fours came to my mind, as I have just eaten some really good ones in a nice Cafe in Regensburg, and wanted to try out to make them myself. I made a simple sponge sheet cake and filled it with the butter-cream and some homemade strawberry-vanilla jam. They were really good and can be made in many different flavor combinations.
I wish you all a very Happy Easter!
