Put your gluten free self-raising flour, sugar and gf baking powder into a large mixing bowl and mix thoroughly.
Then add your eggs and milk and beat until smooth
Grab a second mixing bowl and split the mixture into two even amounts in each bowl.
To one bowl, add 1 tbsp of vanilla extract and to the other, sift in 2 tbsp of cocoa powder. Mix both bowls thoroughly until smooth again.
Set your hob to a low heat and add 1 tsp of oil to your frying pan. Spread the oil around the pan if possible with a brush or kitchen roll.
Using a tablespoon, spoon in one tbsp of the vanilla pancake batter. Then spoon in a tablespoon of the chocolate batter straight on top. Then spoon a tbsp of vanilla mixture on top of that, followed by a tbsp of the chocolate mixture again. Do this as quick as you can and try to spoon in the batter so the pancakes remains a fairly circular shape.
Marble the mixture immediately by using the back of your spoon to create a beautiful marbled pattern.
Allow to cook until the side facing up isn't super wet - then you can flip it without it splattering everywhere! This should take about 2 minutes at a low-ish heat.
Flip it over and cook for a further 1 minute or so and place to one side. Repeat until all the batter is used, using a tsp of oil per pancake to fry them.
Serve up with chocolate sauce and enjoy!
