In a mixing bowl, combine the pumpkin puree, eggs, milk, vanilla extract, cinnamon, nutmeg, ginger, salt, and brown sugar. Whisk together until smooth and well combined. This mixture will coat the bread and infuse it with pumpkin flavor.

Heat a frying pan over medium heat and add 1 tablespoon of butter. Allow the butter to melt and bubble, but not brown.

While the pan is heating, dip each slice of bread into the pumpkin mixture, ensuring both sides are coated well. Let any excess mixture drip off before placing it in the pan.

Place the coated bread slices in the hot pan, making sure not to overcrowd the pan. Cook for about 3-4 minutes on each side, or until golden brown and cooked through. Adjust the heat as necessary to prevent burning.

Once cooked, transfer the French toast to a plate and keep warm while you repeat the process with the remaining slices, adding more butter to the pan as needed.

Serve the pumpkin French toast warm, drizzled with maple syrup and dusted with powdered sugar if desired. Enjoy your delicious fall-inspired breakfast!
