A little abstract buttercream painting on a fully creamed cake - there are many ways to it. Overlaid contrasting colours with dots, or single colour highlights with gold splatters, or a design with horizontally applied strokes. Let me know in the comments which one you like best and also your choice of colours.
Lemon | Raspberry = an airy, just slightly lemony cake, drizzled with a lemon syrup and inbetween those layers a decadent crème patîssière made with 80% high quality raspberry puree, seedless and melt in your mouth.
Chocolate | Cream Cheese = layers of soft and not too sweet chocolate cake with chocolate chips are soaked with berry syrup; two layers of cream cheese mousse are matched by one layer of dark chocolate mousse. However, if you prefer cherry compote instead, just leave a comment and it will be done!
Orange | Blueberry = moist orange cake with blueberries in it, topped with blueberry compote and fresh yoghurt cream. Someone once said the cream takes like the one from "Milchschnitte".
Pistachio Berry | White Chocolate = possibly the most decadent of them all - pistachios and freeze dried berries give this vanilla cake texture, while every cake layer is spread with a most delicious pistachio-white chocolate mousse and some berry puree.
Hazelnut | Vanilla = hazelnut cake that tastes like ice cream, luxurious vanilla crème patîssière with lots of real vanilla and inbetween those two layers is one with hazelnut brittle.
Yoghurt | Fruit = fresh and moist yoghurt cake accompanied by a light and lemony yoghurt cream while the highlight is the thickened fruit puree. You can choose between mango, mixed berries or raspberry.
