Whisk together the eggs, heavy cream, sugar, vanilla extract, and cinnamon in a medium bowl until well blended.
This mixture serves as your custard base for soaking the bread.
Slice your brioche into thick pieces if not already done.
Dip each slice into the custard mixture, ensuring it's soaked on both sides.
Melt the butter in a large non-stick skillet over medium heat.
Once the butter is fully melted and slightly bubbling, place the soaked bread slices onto the skillet.
Cook each slice of bread for about 2-3 minutes per side, or until they're golden brown and cooked through.
Keep a close eye to avoid burning.
Transfer the cooked French toast to a plate and serve immediately, with your choice of toppings like fresh fruit, syrup, or a sprinkle of powdered sugar.
