In a medium size mixing bowl, combine flours, sugar, spices, salt and orange zest (if using).
In another bowl, combine milk, egg replacer mixture (or whisked egg) and vanilla extract.
Add the wet ingredients to dry ingredients and mix until just combined. Set the mixture aside for 15~20 minutes. The batter should be of pouring consistency. Add more milk if it is too thick.
Heat a 8" non-stick pan on medium heat. Add a small pat of butter and wipe it off with a paper towel.
Pour ¼ cup of batter into the pan. Gently swirl the pan around to evenly distribute the batter. Cook for about 1 minute or until the bottom of the crepe starts to leave the pan around the edges. Genty flip and cook for 10~15 seconds.
Remove onto a plate and repeat with the remaining batter. Serve right away with toppings of choice.
