Step‑by‑Step Instructions for Lemon Fluff

Step 1: Prepare the Lemon Mixture
In a large mixing bowl, whisk together the instant lemon pudding mix, 3/4 cup of heavy cream, and fresh lemon juice until smooth, about 2–3 minutes. You’ll know it’s ready when it starts to thicken and resemble a creamy paste. Let this mixture sit for approximately 5 minutes, allowing it to set properly for your lemon fluff.

Step 2: Whip the Cream
In a separate bowl, use an electric mixer to beat the remaining 1 cup of heavy cream, powdered sugar, and a pinch of kosher salt. Whip on medium speed for 3–4 minutes until soft peaks form, indicating that the cream is fluffy and airy. This step is crucial for achieving the light texture that makes your Lemon Fluff so delightful.

Step 3: Combine the Cream and Marshmallow Crème
Once the cream has reached soft peaks, gently add the marshmallow crème to the whipped cream. Mix on low speed for 1–2 minutes until stiff peaks form and the mixture is thick and creamy. This will ensure that your Lemon Fluff has a luscious, indulgent texture, beautifully complementing the citrus brightness.

Step 4: Fold in the Mixtures
Carefully fold the marshmallow mixture and the crushed shortbread cookies into the lemon pudding mixture using a spatula. This should be done gently to maintain the airy texture of the whipped cream while evenly distributing the flavors. You’ll see the creamy lemon fluff starting to come together beautifully!

Step 5: Serve and Garnish
Divide the lemon fluff mixture into individual serving cups or bowls, filling them generously to showcase its vibrant texture. Optional: Garnish with additional crushed shortbread cookies and a sprinkle of lemon zest on top for added color and aroma. Your delicious no-bake Lemon Fluff is now ready to impress!

No-Bake Lemon Fluff Recipe FAQs

How do I know if my lemons are ripe?
Look for lemons that are firm and heavy for their size. Their skin should be bright yellow without any dark spots or blemishes. Ripe lemons will yield slightly to pressure when you gently squeeze them, indicating juiciness. If they have any green patches, they might not be fully ripe yet.

How should I store leftover Lemon Fluff?
Store any leftover Lemon Fluff in an airtight container in the refrigerator for up to 1 day. This helps keep the fluff from losing its delightful airy texture. Remember, the cookies may soften over time, so it’s best enjoyed fresh. If you’re making it ahead, consider adding crushed cookies just before serving to maintain that crunch!

Can I freeze Lemon Fluff?
Absolutely! To freeze Lemon Fluff, transfer it to an airtight container and store it in the freezer for up to 1 month. When you’re ready to enjoy, simply thaw it overnight in the refrigerator. Once thawed, give it a gentle stir to restore its creamy consistency before serving.

What should I do if my whipped cream isn’t forming stiff peaks?
If your whipped cream is not forming stiff peaks, make sure your heavy cream is very cold. You can also try adding a tablespoon of powdered sugar while whipping—it can help stabilize the cream. If it’s still not working, it might be necessary to start over with fresh cream, ensuring the bowl and beaters are also chilled before beginning.

Are there any allergies to be aware of with this recipe?
Yes, this No-Bake Lemon Fluff contains dairy and may also include allergens from the cookies. If you or your guests have dairy allergies, consider using dairy-free whipped cream alternatives and gluten-free cookies. Always check labels to ensure safety for individuals with allergies.

How can I customize the flavors in my Lemon Fluff?
There are so many exciting ways to make this dish your own! You can swap the instant lemon pudding mix for other flavors, like vanilla or chocolate, for a delightful twist. Adding fresh berries or a swirl of berry puree can also enhance the dessert’s visual appeal and taste. Another fun option is using crushed graham crackers instead of shortbread for a different texture!
