In a large measuring cup, combine the milk and orange juice; set aside.
Melt the butter in a microwave-safe dish for 45 seconds; set aside.
In the mixing bowl, add the dry ingredients: flour, sugar, baking powder, baking soda, cinnamon, and salt. Mix on low speed to “sift” the ingredients.
To the dry ingredients, slowly add the melted butter, milk & orange juice, vanilla, and eggs (one at a time). Mix on low/medium speed for 2 minutes.
Allow the mixture to rest while you preheat the cooking surface. If using an electric skillet, preheat to 350. If using a skillet on the stove, preheat on low/medium heat and use additional butter to “grease” the pan so they don’t stick.
Once preheated, pour the batter a quarter cup at a time on to the skillet.
After small bubbles begin to appear and are popping, flip the pancake and cook the other side.
Serve alone (my preference), or with butter, syrup, or topped with fruit.
