One-Bowl Chocolate Sheet Cake with Fudgy Frosting

• Cake
• 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 ¾ cups granulated sugar ≈ 350 g
  Swaps for granulated sugar

  Instead of sugar

  • Less sugar: Up to ¼ less in cookies, muffins and quick breads. Less browning and spread, a drier, more cake-like texture, and bakes go stale sooner.
  • Brown sugar: The same amount, packed. Moister and chewier, with a caramel flavor and darker color.
  • Coconut sugar: The same amount. Darker and caramel-like, a little less sweet; cookies spread slightly less.

• ¾ cup unsweetened cocoa powder ≈ 65 g
  Swaps for unsweetened cocoa powder

  Instead of cocoa powder

  • Natural and Dutch-process cocoa: The same amount. Swap freely when the recipe uses baking powder.
  • Unsweetened chocolate: 1 oz melted unsweetened chocolate for each 3 tbsp cocoa; cut the butter or oil by 1 tbsp. Fudgier and richer.
  • Carob powder: The same amount. Caffeine-free and naturally sweet, but it tastes like carob, not chocolate.

• 1 ½ 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.

• 1 tsp baking powder
  Swaps for baking powder

  Instead of baking powder

  • Baking soda + cream of tartar: ¼ tsp baking soda + ½ tsp cream of tartar for each 1 tsp baking powder. Rises the same if you don't let the batter sit.
  • Baking soda + buttermilk or yogurt: ¼ tsp baking soda for each 1 tsp baking powder, and swap ½ cup of the recipe's milk for buttermilk or thinned yogurt. Good rise with a light tang.
  • Self-rising flour: Use it for the flour and leave out the baking powder and salt. Each cup has about 1½ tsp baking powder and ¼ tsp salt built in, so it only fits recipes close to that ratio.

• 1 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.

• 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.

• 1 cup buttermilk, room temperature
  Swaps for buttermilk

  Instead of buttermilk

  • Milk + lemon juice or vinegar: 1 tbsp lemon juice or white vinegar in a measuring cup, topped up with milk to 1 cup, for each cup. Thinner and a bit less tangy, so bakes are a touch less tender.
  • Plain yogurt + milk: ¾ cup plain yogurt + ¼ cup milk for each cup (with Greek yogurt: ½ cup + ½ cup). The closest match for tang and thickness.
  • Plain kefir: The same amount. Similar tang, a little thinner.

• ½ cup vegetable oil
  Swaps for vegetable oil

  Instead of vegetable oil

  • Another neutral oil: The same amount. No difference.
  • Melted butter: The same amount. Richer, buttery flavor; cakes are a little less moist and firmer once cool.
  • Light olive oil: The same amount. "Light" olive oil tastes mild.

• 2 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.

• ¾ cup hot coffee or hot water
• Frosting
• ½ cup unsalted butter, softened ≈ 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.

• 3 cups powdered sugar ≈ 360 g

• ⅓ cup whole milk
  Swaps for whole milk

  Instead of milk

  • Unsweetened soy milk: The same amount. The closest plant milk for baking: its protein helps things brown and set.
  • Unsweetened oat milk: The same amount. Creamy and mild with a hint of sweetness.
  • Unsweetened almond milk: The same amount. Thinner and less rich, so cakes are a little paler and drier.
