1 tablespoon powdered sugar, plus more for dusting
1 tablespoon lemon zest
Directions
Preheat the krumkake iron. Lightly grease both the iron and a cooling rack with oil.
In a medium bowl, whisk together the melted butter, eggs, granulated sugar, and vanilla extract until smooth.
Add the cardamom, flour, and baking powder and mix with a wooden spoon until well combined.
Add about 2 teaspoons of batter to each cookie section of the krumkake iron. Close the iron and cook for about 45-50 seconds; the cookies are ready when they are very light golden brown.
Use a fork to remove the cookie from the iron and, while it is still pliable, quickly roll it around a wooden or stainless steel cone to form. Let it cool on the cone for at least 1 minute before removing and setting aside on a wire rack. Repeat with the remaining cookies.
Make the filling by using a beater with a whisk attachment. Beat the cream, powdered sugar, and lemon zest until stiff peaks form.
Fill a piping bag with the whipped cream and squeeze it into the cookies.
Dust the krumkake with additional powdered sugar, and enjoy.
