In the large bowl of a stand mixer fitted with the dough hook add warm water, sugar and yeast. Allow to stand for about 5-10 minutes. It should bubble and look frothy.
In a medium bowl, use a whisk to sift together the flour, baking powder and salt.
Once the yeast has bloomed, to the yeast mixture add the egg and oil. Mix on low speed just until combined.
With the mixer on medium speed, gradually add 3 cups of flour. Continue to mix adding the remaining 1/2 cup flour,1 Tbsp at a time. Mix on medium-high just until the dough is no longer sticky and it pulls away from the sides of the bowl.
Transfer dough to a lightly floured surface and using your hands, shape dough into a smooth ball, fold edges under.
Spray the inside of a clean mixing bowl with nonstick cooking spray or brush with oil. Place dough back into the bowl. Cover with a clean cloth and place in a warm draft free place. Let dough rise until doubled in size, for about an hour.
Place the Dutch oven, with the lid into the oven to preheat. Set oven temperature to 450°F.
Once dough has doubled, place it in the middle of a piece of parchment paper. Make small slits on top of the dough with a sharp knife.
Carefully remove the lid from the hot dutch oven and use the corners of the parchment to transfer to the center of the dutch oven. Be careful, it's hot!
Place the lid firmly on top and return to the oven and bake. Bake for 40 minutes.
Remove the lid and bake for an additional 5-10 minutes or until the top is golden brown.
Use the parchment paper to transfer to a wire rack to cool completely, slice and enjoy.
