My dad’s birthday was this weekend, he really enjoys the Despicable Me films so I decided to bake him a minion cake. My first ever character cake! I used a 9″ x 13″ sheet pan and used a vanilla sponge receipe for the cake itself. The one I use is designed for a 7″ round tin but it worked well for this – no batter spillage and baked well! Yay!…
