In a big mixing bowl add the gluten-free flour, yeast, butter, sugar, salt, oil, and warm milk. Mix to combine all the ingredients, and then transfer the dough on a lightly floured surface and kneed for 5 to 6 minutes. The dough should be a little sticky. *Tip: After the dough rises, before rolling it out you can add a bit more flour if it is too sticky to be rolled out. (I've noticed that with gluten-free flours the dough rises better, if it is a bit looser and sticky, if your dough is too hard it may not rise very good)
Place the dough in an oven friendly dish, cover it with a towel, and place it in the oven on 30C degrees. Let the dough rise for about 40 minutes or until doubled in size
Once the dough rises, take it out from the oven.
Preheat the oven to 180C.
Lightly dust your work surface with flour. Divide the dough into 3 parts. Take one part and roll it in a circle shape.
On one side of the dough add the filling of marinara sauce, mozzarella cheese, grated lactose-free cheese, Italian herb mix, and fresh basil.
Fold the dough over and pinch to seal the edges.
Repeat the same with the second piece of dough.
Place the calzones over a baking tray lined up with a baking paper.
Place them in the oven and bake for 30 to 35min
Best served warm.
