In a medium bowl, mix together the dry ingredients (flour through salt). Set this bowl aside.
1 1/3 cups + 1 tablespoon (174 grams) flour, 1/2 cup (55 grams) Dutch-process cocoa powder, 1 teaspoon baking soda, 1/2 teaspoon salt
In a large mixing bowl, stir the remaining ingredients, except for the chocolate chips, together until well combined.
6 1/2 tablespoons (91 grams) refined coconut oil, 2/3 cup (133 grams) brown sugar, 1/2 cup (100 grams) granulated sugar, 1/3 cup (80 grams) ripe banana, 1 tablespoon water, 1 teaspoon vanilla extract
Stir in the dry mixture into the wet, just until combined.
Mix in 3/4 cup (128 grams) chocolate chips. (Ignore that it says 1 cup below - it's a technical issue I can't change)
1 cup (170 grams) chocolate chips
The dough will likely be too soft to form into balls. If it is, place the bowl in the fridge for 20-30 minutes. If you do it much longer, the dough gets very firm. In that case, just let it sit at room temperature until soft enough.
Preheat the oven to 350 °F (175 °C). Line a baking sheet with a piece of parchment paper.
Roll the dough into sixteen 48-gram balls and place about 3" apart on the prepared cookie sheet.
Press down lightly with your palm.
Add the remaining 1/4 cup of chocolate chips on top. (Ignore that it says 1 cup below - it's a technical issue I can't change)
1 cup (170 grams) chocolate chips
Bake for 10 – 13 minutes or until the edges of the cookies are set and the middle doesn’t appear wet. Do not overbake! The middle of the cookie, under the surface, might appear underdone, but it'll continue to cook even after you take the cookies out of the oven.
Let the cookies cool completely on the baking sheet, about 30 minutes
Store in an airtight container at room temperature for up to 5 days. They can also be frozen for up to 3 months.
