In a large mixing bowl, whisk or sift together the flour blend with the baking powder, baking soda, cinnamon if using, and salt.
In a separate bowl or large measuring cup, whisk together the plant-based milk, oil, vanilla extract, and maple syrup.
Pour the wet ingredients into the dry ingredients. Mix just until a batter forms and no visible pockets of dry flour remain. Do not overmix!
Set a nonstick or well-seasoned cast iron skillet over medium heat. After 2 minutes when the oil or vegan butter is hot, ladle ¼ cup (60 mL) of batter per pancake into the skillet, leaving space between each to allow for spreading. Depending on the size of your skillet or griddle, it is likely you will cook the pancakes in more than one batch.
Cook over medium heat for 2 to 3 minutes, or until the edges look set and bubbles form across the surface. Flip and cook the second side for 2 minutes, or until golden brown and cooked through.
Transfer to a warm plate and repeat with the remaining batter, adding more oil or vegan butter as needed between batches.
Serve hot with vegan butter, maple syrup, whipped cream, or fresh fruit as desired.
