Prep Time 20 minutes mins

Cook Time 45 minutes mins

Total Time 1 hour hr 5 minutes mins

Servings 8 servings

Ingredients

  

• For the crust:
• 1 cup graham cracker crumbs (about 8 sheets)
• 2 tablespoons granulated sugar (or zero-calorie sweetener, to taste)
• 3 tablespoons light butter or buttery spread, melted
• Pinch of salt
• For the filling:
• 8 ounces reduced-fat cream cheese (Neufchâtel), softened
• 1 cup nonfat plain Greek yogurt
• 2 large eggs
• 1/2 cup granulated sugar or 1/3 cup erythritol/monk fruit blend (adjust to taste)
• 1 tablespoon cornstarch
• 1 tablespoon pure vanilla extract
• 2/3 cup fresh key lime juice (or regular lime juice)
• 1 tablespoon finely grated key lime zest
• 1/8 teaspoon salt
• Optional topping:
• 1/2 cup light whipped topping or lightly sweetened Greek yogurt
• Extra lime zest or thin lime slices for garnish

Instructions

 

• Prep the pan and oven: Heat oven to 325°F (163°C). Line the bottom of an 8- or 9-inch springform pan with parchment. Lightly mist the sides with baking spray.
• Make the crust: In a bowl, mix graham crumbs, sugar or sweetener, melted light butter, and a pinch of salt until the texture resembles damp sand. Press evenly into the pan, going slightly up the sides. Bake for 8 minutes, then set aside to cool slightly.
• Beat the cream cheese: In a large bowl, beat reduced-fat cream cheese until smooth and fluffy, about 1 minute. Scrape the bowl so no lumps remain.
• Add yogurt and sweetener: Beat in Greek yogurt and sugar (or sweetener) until smooth. Avoid overbeating to keep air bubbles minimal.
• Incorporate eggs: Add eggs one at a time, mixing on low until just combined. Do not whip. Stir in vanilla, salt, and cornstarch.
• Flavor it: Add key lime juice and zest. Mix on low until fully blended and creamy.
• Pour and smooth: Pour filling over the crust. Tap the pan firmly on the counter 3–4 times to release air bubbles. Smooth the top with a spatula.
• Bake low and slow: Bake at 325°F (163°C) for 35–45 minutes, until edges are set and the center wobbles like Jell-O. If the top browns too fast, tent loosely with foil.
• Cool gradually: Turn off the oven, crack the door, and let the cheesecake sit inside for 30 minutes. Move to a rack and cool to room temperature.
• Chill to set: Cover and chill at least 4 hours, ideally overnight. This step locks in the texture and brightens the lime flavor.
• Garnish and serve: Top with a light dollop of whipped topping or a swipe of sweetened Greek yogurt. Add lime zest or slices. Slice with a hot, thin knife for clean edges.

Why This Recipe Works

Save

• Lightened base, full flavor: Greek yogurt and reduced-fat cream cheese create a creamy texture without the calorie load of full-fat versions.
• Bright citrus lifts the sweetness: Fresh key lime juice and zest add zing, so you need less sugar to feel satisfied.
• Smart crust swap: A lighter graham cracker crust with less butter keeps the structure crispy but cuts fat.
• No-water-bath method: Low, steady heat prevents cracks and keeps the interior silky, skipping the hassle of a water bath.
• Make-ahead friendly: The flavor actually improves after chilling, making it ideal for planning ahead.

Storage Instructions

• Refrigerator: Cover tightly and store for up to 5 days.

  Keep the topping separate until serving for the cleanest look.

• Freezer: Freeze whole or in slices for up to 2 months. Wrap in plastic and foil or use airtight containers. Thaw overnight in the fridge.
• Meal prep tip: Slice and portion into single-serve containers.

  Add topping right before eating to keep it fresh.

Health Benefits

• Lower in calories and fat: Reduced-fat cream cheese and light crust ingredients deliver a creamy dessert without the heavy calorie count.
• Protein boost: Greek yogurt adds protein, which helps with satiety and makes the cheesecake more filling than a typical slice.
• Less added sugar: Bright lime flavor means you can cut back on sugar without losing satisfaction. Using a non-nutritive sweetener can drop calories further.
• Vitamin C from limes: Lime juice and zest provide a small dose of vitamin C and a natural flavor punch.

Pitfalls to Watch Out For

• Overmixing the batter: Too much air leads to cracks and a spongy texture. Mix on low and stop when combined.
• Overbaking: A fully firm center in the oven means it’s overdone.

  Pull it when the middle still jiggles.

• Skipping the chill: Cheesecake needs time to set. Rushing this step will leave it soft and less flavorful.
• Using bottled lime juice: Fresh key lime juice tastes brighter and less bitter. If you use regular limes, add a touch more zest.
• Too much sweetener swap: Some sugar substitutes can taste cooling or bitter in high amounts.

  Blend sweeteners or use a partial sugar mix for balance.

Alternatives

• Crust options: Try almond flour or oat flour crust with a little light butter and sweetener. For gluten-free, use gluten-free graham crackers.
• Dairy tweaks: Swap Greek yogurt for skyr. For lactose sensitivity, use lactose-free cream cheese and yogurt.
• No-bake version: Use the same crust but chill it.

  For the filling, blend reduced-fat cream cheese, Greek yogurt, lime juice, zest, sweetener, and 2 teaspoons powdered gelatin bloomed in 2 tablespoons water; pour and chill 6 hours.

• Mini cheesecakes: Bake in a lined muffin tin for 16–20 minutes. Great for portion control and quicker chilling.
• Topping ideas: Add a thin layer of lime curd (lightened with yogurt), fresh berries, or a sprinkle of toasted coconut.

FAQ

Can I use regular limes instead of key limes?

Yes. Regular Persian limes work well.

The flavor is slightly less floral, so add a little extra zest to boost the aroma.

How do I know when the cheesecake is done?

The edges should look set, and the center should still jiggle when you gently shake the pan. It will firm up as it cools and chills.

What sweetener works best?

A blend of erythritol and monk fruit often tastes clean and bakes well. If you’re sensitive to cooling aftertaste, use half sugar and half sweetener.

Can I make it without eggs?

Yes.

Replace the eggs with 2 teaspoons powdered gelatin bloomed in 2 tablespoons cold water, then dissolved. Fold into the filling and chill to set. The texture will be more mousse-like.

Why did my cheesecake crack?

Cracks usually come from overmixing, overbaking, or a rapid temperature change.

Mix gently, bake until just set, and cool gradually in the oven with the door cracked.

How many calories are in a slice?

Estimates vary by ingredients and slice size, but a typical 1/12 slice of this lightened version is roughly 180–230 calories when made with reduced-fat dairy and a low-calorie sweetener.

Do I need a water bath?

Not for this recipe. Baking at a lower temperature and cooling slowly helps prevent cracks without the hassle of a water bath.
