Frequently Asked Questions About No-Bake Lemon Éclair Cake
Can I make No-Bake Lemon Éclair Cake ahead of time?
Yes! In fact, making it ahead of time is recommended. The longer it sits in the fridge, the better the flavors meld together, and the graham crackers soften into a cake-like texture. Prepare it the night before and let it chill overnight for the best results.
Can I substitute the Cool Whip in this recipe?
If you don’t have Cool Whip or prefer not to use it, you can substitute stabilized whipped cream. Just ensure the whipped cream is firm enough to hold its shape and not become runny. You can also use a non-dairy whipped topping if you’re looking for a dairy-free version.
What if I don’t have lemon frosting?
If lemon frosting isn’t available, you can easily make your own lemon glaze by mixing powdered sugar, lemon juice, and a touch of melted butter. This will give you a similar sweet and tangy topping. Alternatively, a simple layer of whipped cream can also work if you prefer a lighter topping.
How long can I store the No-Bake Lemon Éclair Cake?
You can store the No-Bake Lemon Éclair Cake in the fridge for up to 2–3 days. Just make sure it’s tightly covered to maintain its freshness. However, like most desserts, it’s best enjoyed within the first couple of days for optimal texture and flavor.
