In a large bowl, whisk together the flour, baking powder, cinnamon, baking soda, and salt.
Cut the butter into tablespoon size chunks and sprinkle on top of the flour mixture. Work the butter into the flour using a pastry cutter tool, the back of a fork, or by pinching it into small pieces with your fingers. You could also use a food processor with a dough blade.
Stir in the raisins with a fork or spoon, and then add in the yogurt. Use your hands to squeeze the dough to help bring it together.
Turn the dough out onto a floured surface, sprinkle the top with more flour, and pat it out by hand to about 1" thickness. Cut out pieces with a cookie cutter of choice (any shape will work!), fold over scraps, and repeat until all the dough is used.
Space out pieces on a baking sheet and bake until golden brown, 12 to 15 minutes. My daughters think these are best served warm so eat right away or reheat before eating any leftovers.
