Chocolate Peanut Traybake

Hello everyone, I thought I would share the Chocolate Peanut Traybake I made for my sister’s birthday. Chocolate and peanut butter is a favourite combination when I’m baking. I wanted to make a cake based round M&Ms but nothing that was too much as my sister doesn’t have as big a sweet tooth as me. I decided to keep it as a traybake one layer cake and just frost the top of the cake. The bright colours of the M&Ms made this a fun birthday cake to share with the family.
