For the Crust:

  • 1.25 cups all-purpose flour (160 grams)
  • 1 teaspoon baking powder
  • 0.5 cup unsalted butter, cubed (100 grams)
  • 0.5 cup sugar (100 grams)
  • 1 large egg

For the Filling:

  • 3 large eggs
  • 1.75 cups sour cream (400 grams)
  • 0.25 cup sugar (75 grams)
  • 1 tablespoon lemon juice
  • 1 tablespoon cornstarch


  • Mixing Bowls

    Make sure you have a set of different sizes for efficient organization of ingredients.

  • Hand Mixer

    This will help you quickly and evenly beat the eggs and sugar for a smooth filling.

  • Parchment Paper

    Lining your baking form with this ensures an easy release and a perfectly intact tart.

  • Baking Form

    A round tart form with removable sides works best for this recipe, making it easier to serve.


Step 1

Prepare the Crust

Mix the flour and baking powder in a bowl.
Add the cubed butter and mix with your hands until the mixture resembles coarse crumbs.
Add the sugar and egg, then knead into a soft dough.
Refrigerate the dough for 1 hour.
Line the bottom of a baking form with parchment paper.
Press the dough into the form to create the base and sides of the tart.

Step 2

Prepare the Filling

Beat the eggs with the sugar until well combined.
Add the lemon juice and sour cream, then mix well.
Add the cornstarch and stir until fully incorporated.
Pour the sour cream mixture onto the prepared crust.

Step 3

Bake the Tart

Preheat your oven to 340°F (170°C).
Bake for 45-50 minutes, until the edges are golden and the center is slightly jiggly.
Let the tart cool in the oven with the door slightly open.
Refrigerate for at least 2 hours before serving.

Want to make this recipe gluten-free or vegan? 🌱 Here are simple substitutions to accommodate dietary needs:

Gluten-Free Variation: Replace the all-purpose flour in both the crust and filling with a gluten-free flour blend. Ensure that your baking powder is also gluten-free.

Vegan Variation: Substitute the butter with a plant-based vegan butter, and the egg in the crust with a flax egg (1 tablespoon ground flaxseed mixed with 3 tablespoons water, set for 10 minutes). For the filling, use a non-dairy sour cream (such as coconut-based) and replace each egg with 1/4 cup of applesauce.


  • Why is my crust crumbling?

    This can happen if you don't mix the dough ingredients well enough. Make sure to knead until you have a soft, cohesive dough.

  • How do I know when the tart is done?

    Look for the edges to be golden and the center to be slightly jiggly. As it cools, it will set more.

  • Can I use a food processor to mix the dough?

    Yes, using a food processor can speed up the process and ensure that the butter is evenly distributed.

  • Would adding fruits to the filling work?

    You can definitely add fruits! Fold in some berries or thinly sliced apples or pears for added texture and flavor.

  • How can I make the filling thicker?

    If your filling seems too loose, mix an additional teaspoon of cornstarch before pouring it onto the crust.

  • What is the best way to store leftovers?

    Keep your tart in an airtight container in the fridge. It should stay fresh for up to 3 days.
