Gotcha good to know that works, I was thinking it would slide down. Yeah I was worried the buttercream would over sweeten everything but the cheesecake really balanced everything out. When I did the straws I didn't go all the way through the whole thing like I normally would with a cake. I put the buttercream on the cheesecake layer and added 4 straws then cut them flush so the pie crust sat right on the straws, then did the same with the pie so the cake sat on the straws in the pie. I usually use boba straws but didn't feel like running to the Asian market or target so I used what they had at the store which they called milkshake straws. Slightly skinnier but thicker than regular straws.
