In a large mixing bowl, combine flour, salt and baking powder.
In a microwave-proof bowl or liquid measuring cup, melt butter and water together. Once butter is completely melted, whisk and add to dry mixture.
Mix with your fingers until dough comes together. Knead on a lightly floured surface until you have a smooth dough ball. Cover tightly with plastic wrap and let rest for 10-15 minutes.
With your hands, pinch off equal sized pieces. Roll into individual dough balls.
Place back into the bowl. Cover for 10-15 minutes.
On a lightly floured surface, roll out each piece of dough to a 10-12" round. Add extra flour to rolling pin and surface, as needed. (Tip: For perfect rounds, a sharp knife or pizza cutter are extra helpful!)
Preheat a large skillet over medium heat. Place one tortilla at a time. Once bubbles form and rise, flip and cook for 30 more seconds.
As tortillas come off the pan, cover them in a kitchen towel.
Use immediately in any of your favorite recipes that need tortillas. Or, cover in a towel or parchment paper and place in a resealable plastic bag to use later.
