Whisk together eggs, milk, vanilla, cinnamon and nutmeg until smooth.
Heat 1 tbsp of butter onto a skillet at medium heat until it melts.

Re-butter the skillet with the remaining tablespoon. Repeat with the rest of the pound cake.
Plate the French toast in a line, which each slice slightly resting on top of the other. Assemble berries on the side.
