Preheat your oven to 300 degrees. In a medium sized bowl combine butter, crumbs and sugar. Press into the bottom of your spring form pan to make the bottom crust. Try to make the base as even as possible. I have used the side of a coffee mug to press down and flatten the crust as best as I can. Using a handheld or stand mixer beat cream cheese until fluffy. Add condensed milk, eggs and lemon juice and beat until smooth. Make sure mixture is totally blended. Pour on top of your crumb mixture and bake until center of cake springs back when lightly touched. Between 50 and 55 minutes. Allow to cool to room temperature in the pan. Keep refrigerated. Serve and enjoy!
