6. Spread both crumb mixtures on the prepared baking sheet and bake for 10 minutes. Let cool completely.

Strawberry Cake Layers:

1. Preheat oven to 350°F (177°C). Grease and flour two 6-inch round cake pans.
2. In a large bowl, combine cake mix, eggs, melted butter, milk, and strawberry gelatin mix. Mix on medium speed for 2 minutes.
3. Pour batter evenly into prepared cake pans and bake for 20-25 minutes, or until a toothpick inserted into the center comes out clean.

2. Add cream cheese, heavy cream, and vanilla extract. Mix on medium speed until smooth.
3. Add eggs and mix on low speed until just combined.
4. Pour batter into a greased and floured 6-inch springform pan.
5. Wrap the outside of the pan with foil and place it in a large baking dish. Fill the dish with about an inch of water to create a water bath.
6. Bake for 50-60 minutes, or until the cheesecake is just set in the center.
7. Turn off the oven, crack the door open, and let the cheesecake cool in the oven for 30 minutes.
8. Remove from the oven and let cool completely to room temperature, then chill for at least 4 hours.

2. Frost the cheesecake and top with one cake layer. Frost the cake layer and top with the second cake layer. Frost the entire cake.
3. Press the cookie crumb mixture onto the sides of the cake.
4. Refrigerate for at least 30 minutes to allow the frosting to set.
5. Slice and serve.
