In a large bowl, whisk together flour, baking powder, and salt until combined. Set aside.

Pour the wet ingredients into the dry mixture and mix until there are just a few streaks of flour left. With a rubber spatula, fold the chocolate chips into the thick muffin batter. Leave the batter to rest for 15 minutes.
145.83 grams mini chocolate chips
Long Ferment: To long ferment this muffin batter, cover and place in the fridge to cold-ferment overnight, then bake as normal the following morning.
Once the batter has rested, scoop about 20 grams (1 Tablespoon) into each muffin well. The muffin tins will be about ¾ full. This scooper worked perfectly!
You can also sprinkle a few mini chocolate chips on top.
Bake for 10-12 minutes or until the edges are golden brown and a toothpick placed in the center comes out clean.
Keep the muffins in the muffin tin for 5 minutes before removing to cool on a wire rack. Enjoy.
