1. In a medium-sized bowl, combine the graham cracker crumbs and melted butter. Mix until the crumbs are evenly coated and resemble wet sand.
2. Press the crumb mixture firmly into the bottom of a 9-inch springform pan to create the crust. Place it in the refrigerator to set while you prepare the filling.
3. In a large mixing bowl, beat the cream cheese until smooth and creamy. Add the sugar, lemon juice, lemon zest, and vanilla extract, beating until well combined.
4. In a separate bowl, whip the heavy cream until stiff peaks form. Gently fold the whipped cream into the cream cheese mixture until fully incorporated.
5. Gently fold in the blueberries, being careful not to crush them. Spread the mixture evenly over the prepared crust.
6. Refrigerate the cake for at least 4 hours, or until set. For best results, let it chill overnight.
7. Before serving, garnish with extra blueberries and lemon slices if desired. Release the cake from the springform pan and transfer to a serving platter.

As you make this cake, remember my abuela’s advice: cooking with your senses is just as important as following a recipe. Feel the textures, taste the flavors, and enjoy the process!
