Ingredients You’ll Need
For the layers:
- Graham crackers or vanilla wafers – sturdy and dependable
- Heavy cream – whipped into fluffy goodness
- Cream cheese, softened – structure and richness
- Powdered sugar – smooth sweetness
- Lemon zest – bright and fragrant
- Lemon juice – fresh is best
For extra lemon energy:
- Lemon curd – optional but highly encouraged
- Vanilla extract – balances the citrus
Step-by-Step Instructions
- Prep the pan.
Line a 9×13-inch pan with parchment paper or lightly grease it. Future slicing will thank you. - Whip the cream.
Beat heavy cream until soft peaks form. Chill it briefly while you prep the rest. - Make the lemon cream.
Beat cream cheese, powdered sugar, lemon zest, lemon juice, and vanilla until smooth and creamy. - Combine the filling.
Gently fold whipped cream into the lemon mixture until light and fluffy. Don’t rush this. - Build the first layer.
Arrange graham crackers or wafers in a single layer in the pan. Break pieces to fit—no perfection needed. - Add the cream layer.
Spread a generous layer of lemon cream over the crackers, smoothing evenly. - Repeat the layers.
Continue layering crackers and lemon cream, finishing with cream on top. - Chill hard.
Refrigerate for at least 6 hours, preferably overnight. This is when the crackers soften and become cake-like. - Finish and serve.
Top with lemon curd swirls or extra zest just before serving. Slice and enjoy.
Common Mistakes to Avoid
- Skipping chill time.
This dessert needs patience to become cake, not pudding. - Over-whipping the cream.
Grainy cream ruins the texture. Stop at soft peaks. - Using bottled lemon juice.
Fresh juice makes a noticeable difference. - Uneven layers.
It affects slicing. Take a few extra seconds. - Serving straight from the fridge too early.
Let it set fully for clean slices.
