Place a 10-inch nonstick skillet over medium heat and brush the bottom with melted butter. Pour 1/4 to 1/3 cup of batter into the skillet. Immediately lift and rotate the pan in a circular motion to evenly spread the batter across the surface.
Cook the pancake until the edges start to bubble and golden spots form on the bottom. Gently flip using a thin spatula, and cook the second side until lightly browned.
Stack the cooked Swedish pancakes on a plate or fold them into triangles for serving. Garnish with a sprinkle of granulated sugar and a dollop of jam, or pair them with syrup, whipped cream, fresh strawberries, or your favorite toppings. Serve warm and enjoy!
