"This short stack was made with 1/3 cup scoops. Top pancakes with butter, maple syrup, and/or powdered sugar. If storing in the freezer, cut pancake-sized sheets of waxed paper or parchment paper to separate. Store pancakes in a freezer bag."
Whisk baking mix, bran meal, sugar, flax seeds, chia seeds, and baking powder in a large bowl until well mixed.
Whisk milk, eggs, oil, and vanilla extract in a separate bowl until well combined.
Make a well in the center of the baking mix mixture; add egg mixture 1 tablespoon at a time, whisking well after each addition, until batter takes 1 to 2 seconds to fall off the whisk.
Heat a griddle over medium-high heat. Grease with butter. Drop batter by large spoonfuls onto the griddle about 4 inches apart and cook until bubbles form and the edges are dry, 3 to 4 minutes. Flip gently and cook until browned on the other side, 2 to 3 minutes. Repeat with remaining batter.
