Preheat oven to 375 degrees F.
Line a large baking sheet (21” x 15”) with parchment paper and lightly spray parchment with non-stick cooking spray. Set aside for now.
In a large bowl, whisk together eggs, melted butter, molasses, pancake syrup, light brown sugar, ginger, cinnamon, vanilla extract, nutmeg, ground cloves and salt. Whisk until well mixed. Break up any spices that have clumped together. It is important that all the wet ingredients are at room temperature before whisking them together. Too cold of ingredients will clump the melted butter together. Too hot of ingredients will cook the eggs. Make sure all wet ingredients are at room temperature before whisking together.
Whisk in milk and heavy cream.
Taking one piece of bread at a time, dip both sides of the French toast into the mixture. Use a spatula or forks to gently transfer each slice of dipped bread onto the prepared baking sheet. Stir the mixture again before each slice of bread is dipped. The spices tend to sink to the bottom of the bowl, so stirring the mixture between dipping each slice of bread helps to evenly distribute the spices.
Bake in oven for 15 minutes, then remove tray from oven and flip each slice of French toast over and bake for an additional 17-20 minutes (until French toast looks fully baked and soft but not too squishy).
Serve and enjoy!
