How to make a no bake graham cracker crust
Crushing and pressing the crumbs right gives you a sturdy base without baking.
- Line the pan with foil or plastic wrap, leaving an overhang for easy removal. Lightly spray the pan.
- Combine crushed graham crackers and melted butter in a bowl. Mix until crumbs are evenly moistened.
- Press the mixture firmly into the bottom of the prepared pan. Chill while you prepare the filling.
Step-by-step: Lemon cheesecake filling that sets in the fridge
Follow each step and cool the gelatin before combining with dairy. Work quickly with the dissolved gelatin.
- Stir the lemon gelatin into 1/2 cup boiling water until dissolved, about 2 minutes.
- Add 1/2 cup ice water to cool the mixture. Set aside to reach room temperature.
- Beat softened cream cheese with sugar until smooth and lump‑free.
- Gradually beat in sweetened condensed milk until fully incorporated.
- Mix in the lemon juice, then add the cooled gelatin and blend until uniform.
- Gently fold in the whipped topping until the filling is light and even.
- Spread the filling over the chilled crust and smooth the surface. Tap the pan to settle the filling.
- Refrigerate for several hours, or ideally overnight, until the filling is firm.
Make the lemon curd topping
The curd adds a bright, glossy finish. Cook until it thickly coats a spoon.
- Melt butter in a small saucepan over medium heat, then remove from heat.
- Whisk in sugar, lemon zest, and lemon juice until smooth.
- Whisk in the beaten egg and yolk. Return to medium heat and stir constantly.
- Cook about 4–6 minutes, until the curd thickens and coats the back of a spoon.
- Transfer to a bowl, press plastic wrap onto the surface, and cool to room temperature.
Assemble, slice, and serve
- Lift the chilled cheesecake from the pan using the foil overhang and place on a cutting board.
- Spread cooled lemon curd over the set filling in an even layer.
- Slice into squares with a sharp knife. Wipe the blade between cuts for clean edges.
- Top slices with whipped cream and mint leaves, if desired.
Variations, swaps, and scaling tips
- Use a springform pan to serve a round lemon cheesecake instead of bars.
- Substitute digestive biscuits or shortbread crumbs for graham crackers.
- Swap whipped topping for stabilized homemade whipped cream for a fresher taste.
- Double the ingredients and bake sheet pans for large gatherings.
Storage and make‑ahead advice
- Keep leftovers in an airtight container in the refrigerator for up to 4 days.
- Make the curd up to 3 days ahead and refrigerate. Bring to room temp before spreading.
- Chilling overnight yields the best texture.
Helpful tips for success
- Soften cream cheese at room temperature for a lump‑free filling.
- Cool the dissolved gelatin before adding to dairy to avoid separation.
- Press the crust firmly so bars hold together when sliced.
- For glossy slices, chill briefly after adding curd before slicing.
