Optional, for serving: fresh berries, maple syrup, butter, powdered sugar
Instructions
Preheat oven to 425°F. Spray a 9 x 13-inch baking dish with cooking spray and set aside. Stir or whisk together all ingredients in a large bowl just until nicely combined (pancake mix, buttermilk, milk, egg, and oil). The batter will still be a little bit lumpy (and that’s fine) – don’t overmix or the pancakes will be dry.
Pour the pancake batter into the prepared baking dish.
Bake, uncovered, for about 10-15 minutes, or until cooked through in the center.
Slice into squares and serve with desired toppings!
Notes
For a larger batch, bake the pancakes on a rimmed baking sheet (instead of a 9 x 13-inch dish). To do so, increase the measurements to 3 cups of Bisquick, 1 ½ cups of buttermilk, ¾ cup milk, 2 eggs, and 6 tablespoons of oil. The pancakes will be slightly thinner, and will likely be done within about 10-12 minutes.
Do not over-mix the batter. Stir just until the ingredients are combined. You will still have some lumps, which is fine. Over-mixing will result in dense, tough, and dry pancakes.
If time allows, let the batter rest for 5-10 minutes. This gives the leavening agents extra time to react, which results in puffier, fluffier, light pancakes.
The total baking time will vary. If using a glass dish, the pancakes will need closer to 15 minutes in the oven. Metal or dark nonstick pans only require about 10-12 minutes. The pancakes are done when a toothpick inserted in the center comes out clean.
Slice the pancakes into 8 large rectangles or 16 smaller squares. Some readers have even suggested using cookie cutters to cut out fun pancake shapes for your kids!
