Remove and discard the stems from the strawberries, then cut the strawberries into bite-sized pieces. Place in a bowl with the sugar, lemon zest, and lemon juice. Stir well to combine, then let this sit for 15 minutes.

In the meantime, place the graham crackers into a food processor, and pulse until ground into fine crumbs. If you don’t have a food processor, you can crush the graham crackers with a rolling pin instead.

Combine the graham cracker crumbs and melted butter in a bowl, and stir until the crumbs are moistened. Set aside.

In a large bowl, whip together the cream cheese, sweetened condensed milk, and vanilla paste with a hand mixer, for about a minute on medium high speed, until the mixture is smooth and combined.
