I did a Pinkie Pie cake. It was supposed to be a subtle reference but like, ten people in my class knew what it was right away, lol.
For those of you who care, the cake is a pistachio sponge dipped in a mixture of raspberry liqueur and simple syrup. The filling is a raspberry mousseline. The cutie mark and the white blue stripes are fondant, and the border of those is covered with piped Italian meringue buttercream.
