Ingredients

  • 3 large ripe bananas, very spotty, about 1 1/2 cups mashed
  • ½ cup unsalted butter, melted and slightly cooled, plus a little for the pan ≈ 113 g
    Swaps for unsalted butter

    Instead of butter

    • Salted butter: The same amount, with about ¼ tsp less salt per stick (½ cup) elsewhere in the recipe. Nothing noticeable once you cut the salt.
    • Plant-based butter sticks: The same amount. The closest swap.
    • Refined coconut oil: The same amount: solid when the butter is soft or cold, melted when it is melted. It is all fat, so bakes are a bit more tender and rich, with no butter flavor.

  • ¾ cup light brown sugar, packed ≈ 165 g
    Swaps for light brown sugar

    Instead of brown sugar

    • White sugar + molasses: 1 cup granulated sugar + 1 tbsp molasses (light) or 2 tbsp (dark). The same as store-bought.
    • White sugar: The same amount. Crisper, paler cookies with less caramel flavor.
    • Light and dark brown sugar: The same amount, either way. Dark brown sugar tastes stronger and makes bakes a bit darker and moister.

    All 4 swaps for brown sugar

  • 2 large eggs, room temperature
    Swaps for eggs

    Instead of eggs

    • Flax egg: 1 tbsp ground flaxseed + 3 tbsp water for each egg. Binds well but gives less lift, so bakes are a little denser and flatter, with a mild nutty taste and brown flecks.
    • Chia egg: 1 tbsp chia seeds + 3 tbsp water for each egg. Works like a flax egg: good binding, little lift, slightly denser crumb.
    • Unsweetened applesauce: ¼ cup for each egg. Moister and denser, with a soft, slightly gummy crumb if you swap more than one egg.

    All 5 swaps for eggs

  • ¼ cup sour cream or plain yogurt ≈ 58 g
  • 1 tsp vanilla extract
    Swaps for vanilla extract

    Instead of vanilla extract

    • Vanilla bean paste: The same amount. Stronger, with visible vanilla seeds.
    • Vanilla bean: The seeds of 1 bean for each 1 tbsp extract. A deeper, floral flavor and visible seeds.
    • Alcohol-free vanilla: The same amount. Made with glycerin; a slightly milder taste.

    All 5 swaps for vanilla extract

  • 1 ¾ cups all-purpose flour ≈ 219 g
    Swaps for all-purpose flour

    Instead of all-purpose flour

    • Gluten-free 1:1 baking flour: The same amount, a blend that includes xanthan gum. A little grittier and more crumbly, browns faster and dries out sooner.
    • Bread flour: The same amount. More gluten: chewier cookies and bread, tougher cakes.
    • Whole wheat flour: Up to half of the flour. Nuttier, darker and denser.

  • 1 tsp baking soda
    Swaps for baking soda

    Instead of baking soda

    • Baking powder: 3 tsp baking powder for each 1 tsp baking soda. It rises, but bakes come out paler and puffier, cookies spread less, and the extra powder can taste a little bitter.

    More for baking soda

  • ½ tsp kosher salt
    Swaps for kosher salt

    Instead of salt

    • Table salt or fine sea salt: About half as much as Diamond Crystal kosher, about ¾ as much as Morton kosher. The same saltiness when measured this way.
    • Salt by weight: 1 tsp is about 6 grams of table salt, 5 grams of Morton kosher, 3 grams of Diamond Crystal kosher. The most reliable way to swap, especially in baking and brines.

    More for salt

  • ½ tsp ground cinnamon
    Swaps for ground cinnamon

    Instead of cinnamon

    • Pumpkin pie spice or apple pie spice: The same amount. Mostly cinnamon, with ginger, nutmeg and allspice or cloves: a little spicier.
    • Ground allspice or nutmeg: About ¼ the amount. Much stronger and different, but warm in the same way.

    More for cinnamon

Steps

Kid helper. A child can do steps 2, 3, 4 and 5: no knife, no heat. Steps marked “Grown-up” use a knife or heat. Cooking with kids

  1. Heat the oven to 350°F (175°C).
    Butter (how to grease and flour a pan) Grease and flour a pan Coat a pan with fat (and sometimes flour) so baked goods release cleanly. 1. Rub a thin layer of soft butter or shortening into every corner with a paper towel, or use baking spray.2. For cakes, add a spoonful of flour, tilt and tap the pan until it is coated.3. Turn the pan over and tap out the extra flour.4. For chocolate cakes, use cocoa instead of flour so there is no white film. Done when: Every surface, corners included, is lightly coated with no bare spots or thick clumps. How to grease and flour a baking pan: mistakes to avoid
    a 9x5-inch loaf pan, then
    line (how to line a pan) Line a pan Cover the bottom (and sometimes sides) of a pan with parchment or foil so food doesn't stick and lifts out easily. 1. For a sheet pan, tear parchment the size of the pan and lay it flat.2. For a round cake pan, trace the bottom on parchment, cut the circle out and press it in.3. For brownies and bars, leave two long sides hanging over to make handles (a "sling").4. A little grease under the paper holds it in place. Done when: The paper lies flat with no folds where the batter could run under it. How to line a baking pan with parchment: mistakes to avoid
    the bottom and long sides with a strip of parchment so the loaf lifts out easily.

  2. In a large bowl, mash the bananas with a fork until mostly smooth, with a few small lumps left.
    Kid step
  3. Whisk (how to whisk) Whisk Beat ingredients with a whisk to mix them smoothly or to add air. 1. Use a bowl big enough to whisk without splashing; set it on a damp towel to stop it spinning.2. Hold the whisk loosely and move it in quick circles or side to side, touching the bottom.3. For lumpy mixtures, add liquid a little at a time and whisk after each.4. For sauces on the stove, keep the whisk moving across the whole bottom of the pan. Done when: The mixture is even with no lumps or streaks of egg. How to whisk: mistakes to avoid
    in the melted butter, brown sugar, eggs, sour cream and vanilla until well combined.

  4. Sprinkle the baking soda, salt and cinnamon over the top and whisk them in, then add the flour and
    fold (how to fold) Fold Combine a light mixture (whipped cream, beaten whites) or chunky add-ins into a batter gently, so it stays airy. 1. Put the lighter mixture on top of the heavier one, or add the flour or chips.2. Cut a rubber spatula straight down through the middle to the bottom of the bowl.3. Sweep it across the bottom and up the side, then turn it over on top.4. Turn the bowl a quarter turn and repeat.5. Stop as soon as no streaks remain. Done when: There are no dry streaks or white blobs, and the mixture still looks light and puffy. Safety: Batters with raw eggs or flour aren't safe to eat raw.How to fold ingredients into a batter: mistakes to avoid
    with a spatula just until no dry flour shows. A lumpy batter is good.

  5. Scrape the batter into the pan and smooth the top.

    a toothpick (how to toothpick test) Toothpick test A quick way to tell if a cake, quick bread or brownie is baked through. 1. Near the end of the baking time, open the oven and pull out the rack.2. Poke a toothpick or thin skewer into the center (the last place to set).3. Pull it straight out and look at it.4. If wet batter clings, bake a few minutes more and test again. Done when: Clean, or with a few moist crumbs for brownies and fudgy cakes. Wet, shiny batter means not yet. How to test a cake with a toothpick: mistakes to avoid
    poked into the center comes out clean or with a few moist crumbs. If the top browns too fast, lay a piece of foil loosely over it for the last 15 minutes.

Tips

  • The browner the banana skins, the sweeter and more flavorful the bread.
  • No ripe bananas? Roast unpeeled yellow bananas on a sheet pan at 300°F (150°C) for 15 to 20 minutes until black, then cool and use.
  • Ovens vary, so start checking at 50 minutes.
