Heat a 10-11” cast-iron or other nonstick skillet to medium-low. While skillet is heating, combine flour, starch, salt, pepper, garlic powder, onion powder and baking powder in a mixing bowl. Whisk to incorporate.
Whisk in 1 cup milk. If batter is not runny enough to pour, add another ¼ cup milk or as needed.
Combine melted butter and minced garlic in a small bowl and grab a pastry brush or spoon.
Pour a scant ¼ cup batter into the pan and QUICKLY spread with a spatula into approximately 5” circles (in diameter). I can usually get 2 in the pan at a time.
Allow to cook for 3-4 minutes, or until you can easily flip with a spatula without it feeling sticky. Use a thin, firm spatula to flip and cook on the remaining side. In my experience, the first side will be golden-brown all over, whereas the second side will get more traditional “naan-looking” charred spots.
Once both sides have some color and are no longer sticky/tacky to touch, remove from the pan. Remove to a serving plate. Immediately brush with garlic butter or spread a little on with a spoon.
Repeat with remaining batter. NOTE: Cook time will decrease as you go, and you may also need to decrease the heat. Feel free to get creative with your add-ins & toppings! Leftovers keep tightly sealed in the fridge up to 5 days. I reheat in the oven at 400 until warmed through.
