To a large bowl add atta and besan.Now add to it all the spices - kasuri methi, red chili powder, turmeric, ajwain, sesame seeds, salt and baking powder.
Mix it well. Add oil and mix it well with the flour using your hands (rub the flour between your palms to incorporate the oil).The mixture will turn crumbly.Now, start adding water little by little to knead the dough.Knead it for 5 minutes.Cover and rest the dough for 15 to 20 minutes.Now roll the dough into a thin round/square sheet.Meanwhile pre-heat the oven to 180 C.Now you can either use cookie cutter or pizza cutter to shape the mathri.Using a fork poke the mathris so that they don't rise much while baking.Place the squares/rounds on a baking sheet lined with parchment paper. Leave a little space between each mathri.Bake at 180 C for 20-22 minutes, flipping them once half-way.Bake for a little longer if you want them crispy.Let it cool and then store baked methi mathri in an airtight container.
