In a medium bowl, whisk together the cornstarch, nutritional yeast, cinnamon, baking powder, and a small pinch of salt until evenly combined. Add the almond milk and maple syrup, then whisk again until the mixture is completely smooth. Pour the batter into a shallow dish for easy dipping.
Heat a nonstick skillet or griddle over medium heat and lightly coat it with coconut oil.
Dip each slice of bread into the batter, turning to coat both sides evenly. Allow any excess batter to drip off before placing the bread onto the hot skillet.
Cook each slice until golden brown on one side, then flip and continue cooking until the other side is evenly browned and the inside is cooked through. Adjust the heat as needed to prevent burning while ensuring proper cooking.
Remove from the skillet and repeat with the remaining slices, adding more coconut oil between batches if needed.
Serve warm with maple syrup or your preferred toppings.
