Step 1: Prepare the Pancake Batter

1. In a large bowl, whisk together flour, sugar, baking powder, baking soda, and salt.
2. In a separate bowl, mix buttermilk, milk, egg, melted butter, and vanilla extract.
3. Gradually add the wet ingredients to the dry ingredients, stirring until just combined. (A few lumps are okay—don’t overmix.)

Step 2: Cook the Pancakes

1. Heat a non-stick skillet or griddle over medium heat and lightly grease with butter.
2. Pour 1/4 cup of batter onto the skillet for each pancake.
3. Cook until bubbles form on the surface (about 2 minutes), then flip and cook another 1-2 minutes until golden brown.
4. Transfer to a plate and keep warm.

Step 3: Make the French Toast Custard

1. In a shallow dish, whisk together eggs, milk, heavy cream, sugar, cinnamon, and vanilla extract.
2. Dip each cooked pancake into the custard mixture, ensuring both sides are coated but not soaked.

Step 4: Cook the French Toast Pancakes

1. Heat butter in a skillet over medium heat.
2. Cook the custard-dipped pancakes for about 2 minutes per side, until golden brown and slightly crispy.
3. Stack on a plate and serve with your favorite toppings.
