Me, tweaking the recipe on back of the box. I love pancakes and these fit the bill for me. I keep the pancakes warm by placing a clean dishtowel on a plate, add a double layer of paper towels the same length as dishtowel on top of the dishtowel. Place hot pancakes onto the papter towel. Fold both towels up over the hot pancakes to keep warm.
Place lemon juice in measuring cup and add enough milk to make 1 cup; let sit (abt. 5 mins.)while assembling other ingredients.
In bowl mix together bisquick, baking powder, sugar and cinnamon. Add eggs, vanilla and milk mixture, stir until all ingredients are combined. Do not over mix.
Heat griddle until a drop of water will dance across it. Brush about 1/2 tsp oil on griddle. (I only grease the griddle on the first batch, never after that.) Ladel pancake batter onto griddle. When bubbles appear and edges lose some of their shine it's time to flip and cook the other side. Cook until golden. Serve with butter and warm syrup or your favorite pancake toppings.
