This cake has a 10" base made with chocolate cake and chocolate frosting. The top tier is 8" and made out of rice krispie treats.
You can find the chevron cookie cutter I used on Etsy, the company name is Plastic Finatics and I bought their set of three sizes of cutters.
I made the flowers using Wilton's gerber daisy cutters in layers after using a pink powder dust from Hobby Lobby to color the petals. This was VERY time consuming but they ended up worth it and a little more realistic than if I had colored all the gum paste solid. I wasn't really thinking of any particular flower when I made them I just liked the look and went with it. I used floral wire to make them stand up and stick in the cake where I wanted them.
