Buttercream Lego brick cake with fondant lettering. The size of this cake is approximately 11"x5.5" and 3" high for the bottom brick and 5.5"x5.5" and 3" high for the top brick. The knobs on top of the bricks were made using a muffin tray and cut to 1 3/4" circles using a cookie cutter. It's always important to do a crumb layer of buttercream icing to avoid visibly seeing crumbs Such a fun cake!!
