• Preheat the oven to 400 degrees Fahrenheit. Place the butter in a 9x13-inch baking dish, and put it into the oven to melt and become slightly bubbly.
• Using a hand mixer or stand mixer, whisk together the 4 eggs.
• Add in the flour, milk, salt, and sugar. Whisk everything together until the batter is smooth, the batter will be thin.
• Pull the pan out of the oven with the melted butter, and slowly pour the batter on top of the melted butter.
• Put the pan back in the oven and cook for 28-30 minutes. When it's done it will be golden brown around the edges and bubble up over the sides.

Peppered Bacon:

• Preheat the oven to 400 degrees Fahrenheit. Line a baking sheet with aluminum foil.
• Place the bacon lying side by side on top of the aluminum foil, and sprinkle each piece with a little black pepper and brown sugar.
• Bake for about 15-20 minutes or until desired crispness.
• Once the bacon is done, transfer it to paper towels to drain the excess grease.
• Serve the bacon with the Pannukkau and enjoy!
