Add the oat flour and mix until a dough forms. At this stage it will be a little sticky but don’t be tempted to add more flour. Place the dough in a bowl, cover and lave to rest for 10 minutes.
Dust a clean surface with more oat flour and transfer the ball of dough to the counter. Cut the dough into 10 equal sized pieces and roll each piece into a ball.
Take a ball of dough and flatten gently into a puck. Dust the top and bottom with more oat flour.
Use a rolling pin to roll out the balls into 16cm circles. Trim the edges using a 15cm circular cookie cutter or bowl. Alternatively just leave the edges rough if you’d like a home-made feel to your tortillas.
Heat a large dry frying pan over medium heat. Once hot, place a tortilla in the centre and cook for 30 seconds before flipping and repeating on the other side. The cooked side should be browned in spots.
Transfer the cooked tortilla to a clean napkin or tea towel and wrap completely to keep it warm. Repeat with the remaining tortillas, stacking as you go and remembering to wrap with the napkin each time.
Serve warm with fillings of your choice. Alternatively, allow to cool fully then wrap well and place in an airtight container before freezing. When ready to use, defrost at room temperature then warm each tortilla for 10 seconds in the microwave.
