Sift the spelt flour into a large mixing bowl and make a well in the center.
Crack each egg individually into a small cup first, then add to the well.
Gradually add the water and dairy-free milk, whisking continuously until smooth.
Add the vanilla extract, salt, and oil. Mix well until fully combined.
Rest the batter in the fridge for 1–2 hours to eliminate lumps.
Heat a non-stick crepe pan over high heat and lightly grease with oil.
Pour one ladle of batter into the pan, immediately swirling to spread it thinly and evenly.
Cook for 1–2 minutes until bubbles form, then flip and cook for another 1–2 minutes until golden.
Serve immediately with your choice of sweet or savory fillings.
