In a large bowl, combine almond flour, psyllium husk powder, xanthan gum, baking powder, and salt. Mix well.
Add olive oil and gradually add warm water. Mix until a dough forms. The dough should be slightly firm, not sticky.
Let the dough rest for a few minutes at room temperature to allow the psyllium to absorb moisture.
Divide the dough into 5 equal portions and roll each into a smooth dough ball.
Place the dough balls in the fridge for 10–15 minutes to firm up.
Place one dough ball between two sheets of baking paper. Press it down slightly, then roll outwards with a rolling pin, changing directions as you go. Aim for about 1/16 inch thickness (around 2 mm).
Peel the top paper away gently, flip the tortilla, and remove the bottom paper. If wrinkles appear, smooth them out by lightly re-rolling.
Use a lid or bowl to cut a round tortilla. Gather the excess dough and set aside. Repeat with remaining dough, then combine scraps to form the final tortilla.
Carefully transfer the tortilla onto your hand and place it onto a hot non-stick pan.
Cook on medium heat for about 90 seconds on each side, until lightly golden. Avoid overcooking.
Stack cooked tortillas and cover immediately to keep them soft.
