Whisk together the flour and baking powder in a small bowl.
In a larger bowl, whisk together the butternut squash purée, skyr or yogurt, sugar, salt and spices until smooth.
In batches, add the flour to the wet ingredients and mix until you form a shaggy dough.
Move this dough onto a floured work surface and knead for 5-6 minutes or until the dough is tight and smooth. Let this rest on the counter for 20 minutes.
After the dough has rested, divide it into 8 equal pieces. Add more flour to your work surface and roll each piece into a large circle. If you want them thin and pliable, make the dough circles with a 10" diameter. If you want them fluffy and smaller, make them into about a 6-8" diameter.
Bring a skillet to medium heat. Add 1 tablespoon of oil at a time and griddle the flatbreads for 2 minutes on each side, or until they puff and show golden brown spots all over.
Remove from the skillet and serve!
