Prepare syrup by combining maple syrup and zest in a jug, cup, or bowl, and set aside to allow orange flavors to infuse.
Combine the wholemeal self-raising flour, white self-raising flour, raw sugar, and baking powder in a medium bowl.
Make a well in the center and add egg, buttermilk, almond milk, and orange juice. Mix until just combined.
Fold through orange zest and poppy seeds without over-beating the batter.
Cook on a non-stick pan using ¼ cup batter per pancake until golden, then flip.
Repeat with remaining batter until all pancakes are cooked.
Serve warm with prepared orange syrup and toppings of choice.
