Ingredients for Lime Mousse Cheesecake

Every ingredient in this cheesecake plays an important role, from the crunchy crust to the fluffy mousse topping. Here’s what you’ll need.

For the Crust

The base of this cheesecake is a buttery, slightly sweet graham cracker crust that provides a crisp contrast to the creamy layers above.

• 1 ½ cups graham cracker crumbs – This forms the base of the cheesecake. You can also use digestive biscuits or vanilla wafer crumbs.
• ¼ cup granulated sugar – Adds a little sweetness to the crust.
• 6 tablespoons unsalted butter, melted – Holds the crumbs together and gives the crust its rich, buttery flavor.

Tip: If you want to switch things up, try using an Oreo crust or a crushed almond crust for a nutty variation.

For the Cheesecake Layer

This is where the creamy, tangy magic happens. The cheesecake layer is smooth, rich, and packed with fresh lime flavor.

• 16 oz (2 blocks) cream cheese, softened – Always use full-fat cream cheese for the best texture.
• ½ cup granulated sugar – Just enough to balance the tartness of the lime.
• 1 teaspoon vanilla extract – Adds depth to the flavor.
• 2 tablespoons fresh lime juice – Brings out that bright citrusy taste.
• 1 teaspoon lime zest – Adds extra lime flavor and a slight bitterness that enhances the cheesecake’s balance.
• ½ cup heavy whipping cream (whipped to soft peaks) – Helps make the cheesecake light and creamy.

Tip: If you love a stronger lime flavor, add a little extra zest, but be careful not to use too much—it can turn bitter.

For the Lime Mousse Layer

This is the secret to making this cheesecake feel light and airy, rather than heavy like traditional cheesecakes.

• 1 cup heavy whipping cream – The base of the mousse, giving it that soft, fluffy texture.
• ½ cup powdered sugar – Adds sweetness without the graininess of granulated sugar.
• 3 tablespoons fresh lime juice – Infuses the mousse with bright citrus flavor.
• 1 teaspoon lime zest – Enhances the flavor with little bursts of lime.
• 1 teaspoon gelatin powder – Helps set the mousse, giving it structure while keeping it airy.
• 2 tablespoons water – Used to bloom the gelatin before adding it to the mousse.

Tip: If you don’t want to use gelatin, you can substitute agar-agar for a vegetarian-friendly version.

For Garnish (Optional, But Recommended)

A few simple toppings take this cheesecake to the next level, both in appearance and flavor.

• Lime slices – A fresh, colorful topping.
• Whipped cream – Adds extra creaminess.
• Extra lime zest – A little sprinkle on top enhances the citrus aroma.

If you want a contrast in flavor, consider topping with fresh berries like raspberries or blueberries. The tartness of the berries pairs beautifully with the lime.

With all these ingredients ready, you’re just a few steps away from making a creamy, zesty, and absolutely delicious Lime Mousse Cheesecake. In the next section, I’ll walk you through the step-by-step process to ensure you get the perfect texture and flavor every time.

How to Make Lime Mousse Cheesecake (Step-by-Step Guide)

Now that you have your ingredients ready, let’s walk through the process of making this Lime Mousse Cheesecake step by step. Each layer has its own role—a crisp crust, a smooth cheesecake filling, and a light, citrusy mousse on top. Follow these instructions, and you’ll have a dessert that looks as good as it tastes.

Step 1: Prepare the Graham Cracker Crust

A great cheesecake starts with a solid foundation. This buttery, crunchy graham cracker crust adds the perfect contrast to the creamy layers above it.

Instructions

1. Preheat your oven to 350°F (175°C). Grease a 9-inch springform pan with butter or non-stick spray.
2. In a mixing bowl, combine the graham cracker crumbs, sugar, and melted butter. Stir until the mixture resembles wet sand.
3. Pour the crumb mixture into the springform pan, pressing it down evenly with the back of a spoon or a measuring cup.
4. Bake for 8-10 minutes, or until the crust is slightly golden. This helps firm it up, giving it a sturdy base.
5. Let the crust cool completely before adding the cheesecake layer.

Tip: If you prefer a no-bake crust, simply press the mixture into the pan and refrigerate for at least 30 minutes instead of baking.

Step 2: Make the Cheesecake Layer

This layer is smooth, creamy, and infused with fresh lime flavor. The key is to beat the ingredients just enough to make them silky without incorporating too much air, which can lead to cracks.

Instructions

1. In a large mixing bowl, beat the softened cream cheese and granulated sugar with an electric mixer on medium speed until smooth and creamy. Scrape down the sides of the bowl to ensure there are no lumps.
2. Add the vanilla extract, fresh lime juice, and lime zest, then mix again until fully combined.
3. In a separate bowl, whip the heavy cream until soft peaks form. This helps lighten the texture of the cheesecake.
4. Gently fold the whipped cream into the cream cheese mixture using a spatula. Be careful not to deflate the whipped cream—this step keeps the cheesecake layer light and airy.
5. Pour the cheesecake mixture over the cooled crust and spread it evenly with a spatula.
6. Place the cheesecake in the refrigerator while you prepare the mousse layer.

Tip: If your cream cheese isn’t fully softened, you may end up with lumps. To avoid this, let it sit at room temperature for at least 30 minutes before mixing.

Step 3: Prepare the Lime Mousse

This is what makes this cheesecake unique. The lime mousse layer is light, fluffy, and bursting with citrus flavor. The key to achieving the right texture is whipping the cream properly and dissolving the gelatin correctly.

Instructions

1. In a small bowl, sprinkle the gelatin powder over 2 tablespoons of water and let it sit for about 5 minutes. This step is called “blooming,” and it ensures the gelatin dissolves smoothly.
2. Once the gelatin has bloomed, heat it in the microwave for about 10 seconds, just until it’s fully dissolved. Let it cool slightly.
3. In a large mixing bowl, beat the heavy whipping cream and powdered sugar until soft peaks form. This means the cream holds its shape but still has a slight curl at the tip when you lift the beaters.
4. Add the fresh lime juice and lime zest, then mix until combined.
5. Slowly pour the dissolved gelatin into the mousse mixture while continuing to mix on low speed. This will help stabilize the mousse without causing lumps.
6. Pour the mousse over the chilled cheesecake layer, smoothing the top with a spatula.
7. Cover the cheesecake and refrigerate for at least 4 hours (or overnight) to allow it to fully set.

Tip: If your gelatin sets too quickly before you add it to the mousse, warm it slightly and whisk it well before mixing it in.

Step 4: Serve and Enjoy

Once the cheesecake is fully set, it’s time to remove it from the pan and add the finishing touches.

Instructions

1. Run a knife around the edges of the cheesecake before releasing the springform pan to ensure a clean removal.
2. Transfer the cheesecake to a serving plate.
3. Garnish with lime slices, whipped cream, and extra lime zest for a fresh and elegant look.
4. Slice with a sharp knife, wiping it clean between cuts for neat slices.
5. Serve chilled and enjoy the perfect blend of creamy, citrusy goodness.

Tip: For an extra burst of flavor, drizzle the cheesecake with a homemade lime glaze made by simmering lime juice and sugar until slightly thickened.

Now that you’ve mastered the steps to making this Lime Mousse Cheesecake, you’re ready to serve a dessert that will impress everyone at the table. In the next section, I’ll share expert tips, storage instructions, and answers to common questions to help you get the best results every time.

Pro Tips for a Perfect Cheesecake

Use Full-Fat Ingredients

For the creamiest, most flavorful cheesecake, always use full-fat cream cheese and heavy cream. Low-fat versions won’t give you the same rich texture.

Don’t Overmix the Batter

When making the cheesecake layer, mix just until the ingredients are combined. Overmixing can introduce too much air, which can cause cracks as it sets.

Whip the Cream Correctly

For both the cheesecake and mousse layers, the heavy cream should be whipped to soft peaks. If it’s under-whipped, the texture will be too dense. If it’s over-whipped, the mousse can become grainy.

Bloom the Gelatin Properly

Let the gelatin sit in water for at least 5 minutes before heating it. If you don’t let it bloom, it may form lumps in the mousse.

Chill for At Least 4 Hours (Preferably Overnight)

Cheesecake always needs time to set properly. While 4 hours is the minimum, overnight chilling yields the best results—a firmer, more developed flavor.

Use a Hot Knife for Clean Slices

Dip a sharp knife in hot water, wipe it clean, and slice. This will give you smooth, clean cuts every time.

How to Store Lime Mousse Cheesecake

If you have leftovers (which is rare because this cheesecake disappears fast), here’s how to store it to keep it fresh.

At Room Temperature

• Because this cheesecake contains dairy, it should not be left out for more than 2 hours. Keep it refrigerated when not serving.

In the Refrigerator

• Store the cheesecake covered with plastic wrap or in an airtight container for up to 4 days.
• If the cheesecake has whipped cream on top, store it uncovered for the first hour so the topping stays firm.

Freezing Instructions

• This cheesecake freezes beautifully for up to 2 months.
• Wrap individual slices in plastic wrap and store them in an airtight container.
• To thaw, let the cheesecake sit in the fridge overnight.

Frequently Asked Questions (FAQs)

Can I Make This Without Gelatin?

Yes! You can replace gelatin with agar-agar (a plant-based alternative). Use the same amount, but let it simmer in the lime juice for a minute before adding it to the mousse.

Can I Use Bottled Lime Juice Instead of Fresh?

Fresh lime juice is best because it has a brighter, more natural flavor. Bottled lime juice often has preservatives that can make the cheesecake taste artificial.

What If I Don’t Have a Springform Pan?

If you don’t have a springform pan, you can use a deep pie dish or an 8×8 baking dish. Just line it with parchment paper so you can lift the cheesecake out easily.

Can I Make This in Advance?

Absolutely! In fact, this cheesecake is best when made a day ahead because it allows all the flavors to develop. It will keep well in the fridge for up to 4 days.

How Can I Make This Recipe Even More Unique?

Try these variations:

• Swap the graham cracker crust for an Oreo crust for a chocolate-lime twist.
• Add coconut flakes to the crust for a tropical flavor.
• Drizzle with a homemade lime glaze for extra citrusy goodness.
