It's a Red Velvet Lemon Curd Vanilla Cheesecake. See my Inspiration Wedding Cake #1 for details and pictures of the layers.
For the brief description: It was decorated with light pink fondant for the main color, medium and small fuchsia, yellow and purple fondant circles, and light pink purple bow, a figure "2" for the new milestone and other fondant details mimicking a wrapped gift as well as fondant flowers.
I baked, torted and iced the cake (it was actually 2 cakes that were assembled together) and also made the decorations the day before the birthday let them dry overnight, and put it all together yesterday morning.
The little rolled pieces of paper were for support of the little structures and helped keep the round 3-dimensional shapes. I took the pictures around noon and the birthday was later in the evening so I took the pieces of paper out before we headed out.
Actually here is a video of it before the pictures.
