Pannukakku is a Finnish dessert that's kind of like a pancake, but a little fluffier and less dense. It's made by mixing together eggs, flour, milk, and sometimes sugar and vanilla extract.
The mixture is poured into a special type of pan called a pannukakkupannu, which is round and has low sides. The pan is heated on the stovetop until the mixture starts to bubble and steam.
After a few minutes, the pannukakku is flipped over so the other side can cook. It gets a nice golden-brown color on both sides, and when it's done, it's usually cut into pie-shaped slices and served with toppings like fresh berries, syrup, whipped cream or jam.
So, pannukakku is like a yummy pancake that's a little different from what we're used to eating. It's a treat that people in Finland really love, especially during special occasions like holidays and family gatherings.
