Heat beer to about 110°F (43°C)
In the bowl of your stand mixer, pour in the beer, careful to create as little head (foam) as possible. Sprinkle the entire packet of yeast on top, and allow it to sit for 10 minutes. A foam should develop as the yeast and beer begin to interact.
Add in the sugar, yogurt, egg, and salt. Add in about 2 cups of the flour and begin to slowly mix the ingredients using your stand mixer and dough hook.
Slowly add in more flour until the dough starts to stick together and pull away from the side of the bowl. You should end up using between 2½ and 3 cups of flour total.
Once dough comes together, increase the speed on your mixer and allow it to knead the dough for 3-4 minutes.
Coat your bowl with cooking spray, then transfer the dough to the bowl. Roll it around to coat all sides, then cover the bowl with Saran wrap and a kitchen towel. Place in a warm area for 1 hour to rise.
After an hour, the dough should have roughly doubled in size. Divide it into 8 balls, and cover. Again, place in a warm location and allow to rise another 30 minutes.
Roll out each ball into an oval shape, about 4-5mm in thickness. Brush one side with melted butter, then place buttered-side down on grill or skillet over medium-high heat. While the first side cooks, brush the other side with melted butter. Watch for small air bubbles to form. Once they appear, flip the bread to cook the other side. You'll cook each one 45-60 seconds per side, depending on how hot your skillet or grill is.
Serve warm and enjoy!
