What I decided to do is a sheet cake 11 X15 with a smaller pyrimid on top. I'm using a 8x8, 6x6 and 4x4 pan and carving it. Then using fondant to cover and luster dust for the shimmer. I'm hoping its dazzling! LOL
Let us know how it turns out! I guess I should have clarified that on the diagrams above they use an 8-inch 2-layer square, lined up with the edge of counter. Go in 2-inches on each side at a 45 degree angle I believe. That should give you an 8" sq. x 8" H pyramid. Sorry for not doing it sooner! HTH!
Awesome! Make sure to post pics. I haven't even tried this yet. I found the diagram somewhere, don't remember where a couple years ago, and have been wanting to try it. Just haven't had the right occasion to yet. Can't wait to see the finished product!
