This lemon chiffon pie is filled with a perfectly creamy no-bake lemon custard. Not to mention the extra crispy Oreo crust is another factor makes you fall head over heels for this dessert.
If you're looking for such creamy, fluffy, sweet with a hint of sour pie, then this no-bake lemon chiffon pie or lemon meringue pie is definitely for you. Better yet, not a fan of pie? You can easily transform this into a lemon chiffon cake. But I bet the extra-crispy Oreo crust in this pie will definitely change your mind.
No-bake lemon chiffon cake deconstruction
This no-bake pie has two parts: the creamy filling and the crispy crust.
The lemon chiffon filling, just like chiffon cake, is leavened with whipped egg whites. Also, the addition of egg yolks and heavy cream help to makes the filling moister and richer. That is why it is safe to also call this as lemon meringue pie.
The crispy crust is made of Oreo cookies. You have an option to bake and not to bake the crust. Though the baked version of Oreo crust will be slightly crispier than the no-bake one, you can barely tell the differences between the two.
What goes in this no-bake pie recipe?
For Oreo crust:
Oreo cookies - you'll need 2 packs of Oreo for the crust, about 15 cookies with their fillings removed. Then you can either crush them by using a food processor or a rolling pin. If you insist on using a rolling pin, simply put the cookies inside a zip log bag then gently crush them. I prefer using the rolling pin method simply because it's faster and easier to handle.
Butter - I used unsalted butter in the recipe. However, if you like your crust a little bit lightly salty, you can always switch for salted butter.
Substitution - You can substitute Oreo crust for any other types of crackers such as saltine cracker. If you do, make sure to use unsalted butter as these crackers are already salty.
For lemon chiffon fillings
Gelatin sheets - because this is a no-bake pie, the appearance of gelatin is a must to bind everything together. 4 gold-rank gelatin sheets are called in the recipe, you can substitute for 1 packet of gelatin powder if prefer. You can read more about gelatin types, ranking, and usage here.
Egg whites - to create the voluminous filling, make sure to whip the egg whites to stiff peaks. If egg whites are too soft, the filling will become dense instead of airy and fluffy. That is why I also like to call this as lemon meringue pie.
- You can use pasteurized eggs instead of regular eggs as the whipped egg whites/meringue in this recipe is not cooked. However, it might be hard or impossible to get a stiff peak with these eggs because the pasteurization process affects the ability of the proteins in the eggs to get firm.
Egg yolks - as mentioned above, the yolks help this no-bake lemon chiffon pie moister and richer. Egg yolks are cooked on a double boiler then carefully tempered and incorporated in the egg whites with the help of sugar and heavy cream.
Heavy cream - another factor that helps the pie creamy and tasty.
Lemon - Lemon pie won't be completed without the most important ingredient "lemon". You'll need both lemon zest and fresh squeezed lemon juice for this chiffon cake recipe.
