In a large bowl, combine the flour, instant yeast, salt, sugar, and chocolate chips, stirring until everything is evenly distributed so the chips are not clumped in one area of the dough.
4 cups (500 g) all-purpose flour, 2¼ tsps (7 g / 1 packet) RapidRise yeast, 1¼ tsps (7 g) table salt, 2 tbsps (25 g) granulated sugar, ¾ cup (120 g) semi-sweet chocolate chips
Add the warm water and oil, then mix until a shaggy dough forms. If using a stand mixer fitted with a dough hook, mix on low speed for 2 to 3 minutes, then increase to medium-low speed and continue mixing for 4 to 5 minutes until the dough becomes mostly smooth and elastic. If mixing by hand, knead the dough for 8 to 10 minutes until it becomes mostly smooth. The dough may tear slightly as the chocolate chips work through it, which is expected and part of how the texture develops.
1¼ cups (300 ml) warm water, 2 tbsps (30 ml) neutral oil
Shape the dough into a ball, place it in the bowl, cover, and let it rise until doubled in size, which typically takes about 1 to 2 hours depending on the temperature of your kitchen.
Turn the dough out onto a lightly floured surface, gently deflate it, and press it into a rough rectangle. Fold the bottom up and the top down, then turn the dough and roll it into a tight log while pulling the dough toward you to shape it.
Place the dough seam-side up in a well-floured 10-inch (25 cm) oval banneton or 9-inch (23 cm) round banneton, or use a medium bowl lined with a well-floured towel. Cover and let it rise again for 30 to 60 minutes. The dough is ready when it looks slightly puffy and slowly springs back when pressed with a finger.
About 30 minutes before baking, place a 5 to 6 quart (4.7 to 5.7 L) Dutch oven with lid in the oven and preheat to 475°F (245°C) so the pot is fully heated when the dough goes in.
Turn the dough out onto a piece of parchment paper, score the top with a sharp knife or lame, and carefully transfer it into the hot Dutch oven. Cover and bake for 20 minutes, then remove the lid and continue baking for another 20 to 25 minutes at 450°F (232°C) until the crust is golden.
The bread is done when it sounds hollow when tapped on the bottom or reaches an internal temperature of 205 to 210°F (96 to 99°C). Remove from the pot and let it cool completely before slicing.
