Preheat oven to 375 degrees F
Grease a 9X13 inch baking dish with gluten free cooking spray or butter (you can use Melt dairy free butter)
Add peaches, sugars, vanilla and almond extracts, cinnamon, nutmeg, corn starch, cream of tartar, water, and lemon juice and stir until combined.
Drop pats of butter evenly over the top.
Bake uncovered for 20 minutes.
While peaches are baking, whisk together gluten free flour, baking powder, salt, and sugars.
Stir in vanilla and whipping cream. The mixture should be pretty wet and sticky, like a drop biscuit.
Remove peaches from the oven.
Increase oven temperature to 425 degrees F
Top the peaches with prepared dough using a spoon or cookie scoop. There should be 9 or 10 scoops and there will be a little space in between each one.
Use a pastry brush to brush the leftover cream in the measuring cup on top of the biscuits, then sprinkle with 2-3 tablespoons of coarse sugar (the coarse sugar is optional, but oh, so good)
Return the cobbler to the oven and bake uncovered for 15-20 minutes, until the crust is golden brown.
Top with vanilla ice cream or fresh whipped cream (or dairy free alternatives) and serve!
