In a large mixing bowl, combine water, yeast, and sweetener. Let it sit for about 5 minutes to allow the yeast to activate and bloom.
Preheat your oven to 450 degrees Fahrenheit.
Add flour, salt, baking powder, and oil to the yeast mixture. Mix well until the dough forms.
Cover the bowl with a clean kitchen towel and let it rise in a warm, draft-free place until the dough doubles in size, usually for about 1-2 hours.
Once the dough has doubled in size, pour it into a prepared baking pan and let it rise for another 30 minutes.
Make some holes in the dough using your fingertips and drizzle with olive oil. Sprinkle with chopped rosemary and sea salt.
Bake the bread in the preheated oven for about 17-20 minutes or until it’s firm and golden brown.
