Chocolate Chunk Banana Bread

Ingredients

• 1¾ cup / 210 g All-purpose flour
• ¾ cup / 150 g Light brown sugar
• 2 large / 272 g Ripe bananas
• 2 Large eggs
• ⅓ cup / 80 ml Canola oil
• ¼ cup / 60 ml Milk
• 1 tsp Baking soda
• 1 tsp Ground cinnamon
• ½ tsp Kosher salt
• 1 tsp Vanilla extract
• ½–¾ cup / 100 g Semisweet chocolate chunks

Method

1. Heat the oven to 350°F / 175°C, or 325°F / 165°C if the oven is convection. Lightly oil a 9-by-5-inch loaf pan. That oil on the pan is a thin coat and is not in the measured ingredients. A parchment sling makes the loaf easier to lift out. The parchment is extra. It is not in the count.
2. Mash the bananas. The linked page says 2 large ripe bananas, about 1 cup mashed. This version uses 2 large bananas. A USDA large banana is 136 g, so the two bananas are 272 g. A USDA cup of mashed banana is 225 g, and that cup is not the amount used.
3. Beat the mashed bananas, the canola oil, the milk, the brown sugar, and the vanilla until the sugar is mixed through. Beat in the eggs. The page says canola or another light oil, and milk of your choice. This version uses canola oil and whole milk. The flour line is 1¾ cups and also 210 g. This version uses 210 g. The brown sugar line is ¾ cup and also 150 g. This version uses 150 g.
4. Whisk the flour, baking soda, cinnamon, and kosher salt in a small bowl. The page says kosher or fine sea salt. This version uses kosher salt. Stir the dry mixture into the banana mixture only until the flour disappears. A few streaks left in the bowl are better than a tough loaf.
5. Fold in the chocolate chunks. The page writes ½ to ¾ cup and also 100 g. This version uses 100 g of semisweet chocolate chunks. Set a few extra chunks on top of the batter if you want them to show. Those extras are not in the 100 g, so they are not in the count.
6. Pour the batter into the pan. Bake about 70 minutes, until a toothpick in the center comes out with a few moist crumbs and no wet batter. Start checking at 60 minutes. Ovens run hot, and a dry loaf is past the point the page is aiming for.
7. Cool the loaf in the pan for 10 minutes. Loosen the sides and turn it onto a rack. Let it cool before you slice it, or the crumb slumps. The page does not say how many slices the loaf makes. Ten slices is the cut used here.
8. Keep the loaf covered at room temperature for a couple of days, or in the fridge for about a week. The page also freezes the wrapped loaf for a few months. Thaw a slice on the counter, or warm it a short time until the center is no longer cold.

Nutrition

Kitchen estimate only, not lab-verified. Counted as 1 of 10 slices: the all-purpose flour, the light brown sugar, two large bananas, the eggs, the canola oil, the milk, the baking soda, the cinnamon, the kosher salt, the vanilla, and the semisweet chocolate. The post and the linked page do not say how many slices the loaf makes. Ten slices is the cut used here. The oil on the pan is not measured, so it is not in the count. The few extra chocolate chunks on top of the loaf are not in the 100 g, so they are not in the count. The flour line is 1¾ cups and also 210 g. A USDA cup of all-purpose flour is 125 g, so 1¾ cups would be 219 g. The written 210 g is used. The brown sugar line is ¾ cup and also 150 g. A packed USDA ¾ cup is 165 g. The written 150 g is used. The page says about 1 cup mashed for the bananas. A USDA cup of mashed banana is 225 g. Two large bananas are 136 g each, and the written 272 g is used. The oil line is ⅓ cup and also 80 ml. A USDA cup of canola oil is 218 g, so ⅓ cup is 73 g. The cup measure is used. The page says milk of your choice. Whole milk is the row, and ¼ cup is 61 g. The chocolate line is ½ to ¾ cup and also 100 g. The written 100 g is used. The salt is kosher. A half teaspoon is counted at the Morton density, 2.4 g, not the 3 g of table salt. Added sugars are the brown sugar, the vanilla, and the chocolate, 20 g per slice. About 4 g of other sugars per slice sit in the bananas and the milk.

Guest diet / allergy swaps

Short kitchen notes for guests. A fuller gluten-free or dairy-free ingredient list, when we have one, is in the panels below.

• Dairy-free

  The dairy is the milk and any milk in the chocolate. The page says milk of your choice. Use ¼ cup / 60 ml of unsweetened plain soy milk or oat milk, and 100 g of chocolate chunks whose package says dairy-free. The oil is canola, not butter. Read the chocolate. Some plant milks add soy, and some group coconut with tree nuts. This is a kitchen note, not a dairy-free certification.

  • United States: Plant milk for the milk, and chocolate whose package says dairy-free. The oil is already canola. The flour is still wheat.
  • United Kingdom: Use an unsweetened plain plant drink and dairy-free chocolate. This does not change the flour.

• Gluten-free style

  The wheat is the all-purpose flour. Use 210 g of a cup-for-cup blend whose bag says gluten-free. Read the chocolate and the baking soda. Bananas, brown sugar, eggs, canola oil, milk, cinnamon, salt, and vanilla do not call for wheat. The loaf may need a few more minutes. This is a kitchen note, not a gluten-free certification.

  • United States: A cup-for-cup blend whose bag says gluten-free, at the same 210 g. Read the chocolate and the baking soda.
  • United Kingdom: A free-from flour marked gluten free, at the same weight. Check the chocolate.

• Egg-free

  The loaf uses 2 large eggs. A flax or chia stand-in is a different bread, and this batter was not tested that way. Skip this loaf if it has to leave out eggs. This is a kitchen note, not an allergen clearance.

  • United States: This batter uses 2 eggs and was not tested without them. Skip the loaf if the eggs have to come out.
  • United Kingdom: The same note. This is not an egg-free loaf.

• Soy-free chocolate

  The semisweet row used for the count is a candy that often includes soy lecithin. Use 100 g of chopped chocolate whose package does not list soy. The rest of the batter does not call for soy unless the milk you choose does. This is a kitchen note, not an allergen clearance.

  • United States: Use chocolate whose package does not list soy. Read the milk if you swap it.
  • United Kingdom: Check the chocolate for soya lecithin. The rest of the batter does not call for soya unless the milk does.
