In a food processor, pulse the cookies with fillings and all into fine crumbs.
Add half of the melted butter and mix until well combined. If needed, add more butter to get wet sand texture. (TIP: Squeeze a small amount of cookie mixture in your hand. If it holds its shape, then it's ready. You don't want to dry or too oily cookie mixture.)
Transfer the cookie mixture into 9-inch springform pan and spread it evenly on the bottom and about 1-inch up the sides. Refrigerate.
To make the filling:
In a mixing bowl with paddle attachment, beat cream cheese until fluffy.
Add sweetened condensed milk, raspberry jam, lemon juice,lemon zest and food coloring, if using. Mix until smooth and well combined, scraping the sides of the bowl half way.
Pour the filling into the prepared crust and refrigerate until set, at least 3 hours or overnight. You can also put it in the freezer.
To serve, remove the sides of the pan and decorate the cheesecake with fresh raspberries and lemon slices, if desired.
Notes
Note 1: 1 package is 370g cookies.Note 2: Don't add all the butter at once. Depending on your cookies, you may not need all of it. Choose unsalted butter, if you can.Note 3: Buy a block of plain, full fat cream cheese for the best flavor and texture. For ultra-smooth texture, soften cream cheese at room temperature for 1-2 hours.Note 4: You'll get 3 tablespoons of juice out of 1 large lemon.Note 5: I prefer seedless raspberry jelly for nice and smooth filling. My homemade raspberry jelly works great!Note 6: Food coloring is optional. However, the natural color of the cheesecake is dull pink color, and I like to brighten it up with a touch of red food coloring. 1 small drop of gel, or 1/8 teaspoon of liquid.Storing Tips: Keep the leftover cheesecake, tightly covered, in the fridge for up to 5 days. This cheesecake freezes well too. Freeze it in airtight container for up to 1 month.
