  9. Cool for 15-20 minutes, remove from springform pan and drizzle glaze over top of coffee cake.

Recipe Notes

If you prefer you can add the blueberries to the top of the coffee cake prior to adding the streusel mixture instead of folding them into the batter.  Or go all wild and crazy and add 1/2 to the batter and 1/2 to the top.
