Finnish oven pancake

EQUIPMENT
1 half sheet pan. 18x13 inch
INGREDIENTS
4 cups milk
4 eggs
2 cups all-purpose flour
½ teaspoon salt
3 tablespoon sugar
2 teaspoon ground cardamom (from green pods)
3 tablespoon butter
INSTRUCTIONS
Mix the dry ingredients together in a large bowl.
Add in the milk and eggs and give it a whisk.
Let your batter rest for at least 30 minutes. The clumps will even out when the flour swells.
Warm your oven to 400 F (200 C)
Melt the butter on the sheet pan in the oven. Take out the pan and give it a swirl so the butter spreads out evenly.
Pour your batter on the hot pan. Bake for 30-40 minutes until nicely browned.
Giant bubbles will form on the pannukakku while baking. You can break them while baking, so you get a more even color.
Serve slightly cooled with strawberry jam.
