Preheat your oven to 350°F (175°C). Grease a 6-inch round cake pan and line the bottom with parchment paper.
In a large mixing bowl, crack in the eggs and whisk until the yolks and whites are best friends.
Add the yogurt and sweetened condensed milk. Stir until it’s all smooth and dreamy—no lumps allowed.
Pour the batter into your prepared pan and give it a little shimmy to level it out.
Bake for about 30 minutes, or until the top is golden and the center jiggles ever so slightly (yes, we like a little jiggle).
Let it cool completely before removing it from the pan. Chill in the fridge for a couple of hours for best texture.
