Add butter to an 8x8 baking dish.
Put the dish into a cold oven and preheat to 400 allowing the butter to melt while the oven preheats.
Remove from the oven as soon as butter is melted.
In a separate bowl combine Bisquick, yogurt, and soda.
Stir until just combined.
Do not over-stir.
If the dough is too sticky, add some more Bisquick.
Pat the dough into a square then cut like a tic-tac-toe to form 9 biscuits.
Form the biscuits into circles then place in the butter.
Bake in the oven for 20 minutes until golden brown.
