Preheat oven to 355° F. / 180° C. and grease an 8-inch /2 0 cm springform pan. Set on a baking sheet and set aside. *Note: if you are using a dark springform pan, reduce temperature to 340F / 170C.
When the cake has baked for 20 minutes, remove from oven. (The egg mixture should have set somewhat so that the crumbs won't sink into the cake. If it is too liquidy still, return to the oven for a few more minutes.) Evenly sprinkle the crumb mixture over the top. Return to the oven and bake a further 20 - 25 minutes or until the edges are starting to become golden and pull away from the edge and the center is set. As long as it's not too jiggly and a tester inserted in the centre comes out with just crumbs (not liquid), it's ready to take out of the oven. It should have bake about 60-65 total, including all 3 steps.
