Easy Lemon Quark Cheesecake

Cheesecake used to scare me. All that talk about water baths and cracking tops made me think it was too hard for a regular Tuesday night dessert. But then I discovered quark, and everything changed. This German-style soft cheese makes the creamiest, easiest cheesecake you’ve ever had.

I stumbled across quark at my local grocery store and decided to give it a try. It’s lighter than cream cheese but still rich enough to make you happy. Add some bright lemon juice and zest, and you’ve got a dessert that tastes fancy but comes together in about 20 minutes of actual work.

The best part? No water bath needed. No worrying about cracks. Just mix, pour, and bake. My kids ask for this one more than any other dessert I make, and my husband always goes back for seconds.

What Kind of Quark Should I Use?

For this cheesecake, you’ll want to use plain, unflavored quark with a smooth, creamy texture. Most grocery stores carry quark in the dairy section near the yogurt and sour cream, and any brand will work well for this recipe. If you can’t find quark at your local store, you can substitute it with an equal amount of thick Greek yogurt or even cream cheese, though the flavor will be slightly different. Make sure your quark is well-chilled before using it, as this helps the cheesecake set properly and gives you that perfect creamy consistency.

Options for Substitutions

This cheesecake has some room for swaps, though a few ingredients are pretty important to keep:

• Quark: This is the star of the show and really shouldn’t be substituted if you want authentic results. If you absolutely can’t find quark, you can mix equal parts cream cheese and Greek yogurt, but the texture will be different.
• Vanilla sugar: No vanilla sugar? Just use regular sugar and add 1-2 teaspoons of vanilla extract to the mixture. The flavor will be just as good.
• Corn starch: You can swap this with all-purpose flour using the same amount, but cornstarch gives a smoother texture. If using flour, make sure to mix it well to avoid lumps.
• Heavy cream: You can use whipping cream instead, but avoid anything lower in fat content as it won’t whip properly and the cheesecake might not set right.
• Lemon juice: Fresh lemon juice is best, but bottled will work in a pinch. You could also try lime juice for a different citrus twist, using the same amount.
• Sugar amount: Feel free to reduce the sugar by up to 1/4 if you prefer less sweetness, but don’t eliminate it completely as it helps with the structure.

Watch Out for These Mistakes While Baking

The biggest mistake when making lemon quark cheesecake is not beating your egg whites to stiff peaks, which can result in a dense, heavy texture instead of the light, airy consistency you’re after – make sure your bowl and beaters are completely clean and free of any grease.

Another common error is overmixing once you fold in the egg whites, as this deflates all that air you just worked so hard to create – gently fold with a spatula using a cutting motion until just combined.

Temperature control is crucial here, so bake at a lower temperature (around 325°F) and avoid opening the oven door during the first hour, as sudden temperature changes can cause your cheesecake to crack or collapse.

Finally, don’t skip the cooling process – let it cool gradually in the oven with the door slightly open, then chill completely before serving to prevent cracks and ensure the perfect creamy texture.

What to Serve With Lemon Quark Cheesecake?

This light and tangy cheesecake is perfect on its own, but I love serving it with fresh berries like strawberries, blueberries, or raspberries that complement the bright lemon flavor. A simple berry compote or a drizzle of berry coulis makes it feel extra special without overwhelming the delicate quark texture. You could also add a dollop of whipped cream or a light dusting of powdered sugar if you want to dress it up a bit. For a nice contrast, try serving small slices alongside some crisp shortbread cookies or buttery ladyfingers for dipping.

Storage Instructions

Refrigerate: This lemon quark cheesecake needs to be kept cold in the fridge at all times. Cover it with plastic wrap or store it in an airtight container for up to 5 days. The flavors actually get better after a day or two, so don’t worry about making it ahead of time!

Make Ahead: This cheesecake is perfect for making a day before you need it. The texture sets up beautifully overnight, and the lemon flavor really develops. Just wrap it well and keep it chilled until you’re ready to serve.

Freeze: You can freeze individual slices wrapped tightly in plastic wrap for up to 2 months. Let them thaw in the fridge for a few hours before serving. The texture might be slightly different from fresh, but it’s still delicious and creamy.

• Calories: 2300-2500
• Protein: 110-125 g
• Fat: 130-150 g
• Carbohydrates: 190-210 g

Ingredients

For the cheesecake base:

• 4 1/2 cups plain quark (1000g)
• 4 tbsp lemon juice (freshly squeezed for best flavor)
• 1/4 cup vanilla sugar
• 3/4 cup sugar (granulated white sugar works best)
• 1/2 cup corn starch (for a smooth, firm texture)
• 4 egg yolks

For the whipped elements:

• 3/4 cup heavy cream (cold and full-fat for best whipping results)
• 4 egg whites

Step 1: Prepare the Baking Equipment and Ingredients

• 4 egg whites
• 4 egg yolks

Preheat your oven to 350°F (175°C).

Prepare a springform pan by lining it with parchment paper or greasing it to prevent sticking.

This is also a good time to separate the eggs into whites and yolks, setting each aside for later steps.

Step 2: Whip the Heavy Cream and Egg Whites

• 3/4 cup heavy cream (400 g)
• 4 egg whites (from Step 1)

Using a hand or stand mixer with the whisk attachment, beat the heavy cream until stiff peaks form.

Transfer it to a separate bowl and set aside.

Next, beat the egg whites separately until they also reach stiff peaks, and set them aside as well.

I recommend thoroughly washing the whisk between whipping the cream and egg whites so both whip up properly.

Step 3: Mix the Cheesecake Batter

• 4 1/2 cups plain quark (1000 g)
• 3/4 cup sugar (150 g)
• 1/4 cup vanilla sugar (50 g)
• 4 egg yolks (from Step 1)
• 4 tbsp lemon juice
• 1/2 cup corn starch (70 g)

In a medium-sized mixing bowl, combine the quark, sugar, vanilla sugar, egg yolks, lemon juice, and corn starch.

Use a whisk to stir everything together until well blended and smooth.

This will form the base of your cheesecake batter.

Step 4: Incorporate Cream and Egg Whites

• whipped heavy cream (from Step 2)
• beaten egg whites (from Step 2)
• cheesecake batter (from Step 3)

Carefully fold the whipped heavy cream (from Step 2) into the cheesecake batter (from Step 3) until just combined.

Then, gently fold in the beaten egg whites (from Step 2), being careful not to deflate them.

This will keep your cheesecake light and airy.

I always take my time here, using a spatula to gently fold until everything is homogeneous.

Step 5: Bake the Cheesecake

• batter (from Step 4)

Pour the finished batter (from Step 4) into your prepared springform pan.

Smooth out the top if needed.

Place in the preheated oven and bake for 60-70 minutes.

If you notice the cheesecake turning too brown, loosely cover the top with foil for the remainder of the baking time.

Step 6: Cool and Chill the Cheesecake

Once done baking, turn off the oven and open the door slightly.

Let the cheesecake sit in the oven for another 10-15 minutes.

Then, remove it from the oven and let it cool completely at room temperature.

After cooling, cover and refrigerate the cheesecake for at least several hours, or up to a week for best texture.

I like to let my cheesecake chill overnight to ensure it sets perfectly.

Step 7: Serve

Once the cheesecake is fully chilled and set, remove it from the refrigerator, slice, and serve.

It pairs beautifully with a side of whipped cream or fresh berries if desired.
