Ingredients

  • Lemon sugar topping
  • 3 tbsp turbinado sugar, or coarse sugar
  • 1 tsp lemon zest
    Swaps for lemon zest

    Instead of citrus zest

    • Another citrus zest: The same amount. A different citrus aroma; any of them brightens a dish.
    • Dried citrus peel: 1 tsp dried for each 1 tbsp fresh zest. Milder and a little bitter.
    • Lemon or orange extract: About ¼ tsp extract for each 1 tsp zest, to taste. Strong citrus flavor, no texture.

    More for citrus zest

  • Muffins
  • ¾ cup granulated sugar, 150 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.

    All 4 swaps for sugar

  • 1 tbsp lemon zest, from about 2 lemons
    Swaps for lemon zest

    Instead of citrus zest

    • Another citrus zest: The same amount. A different citrus aroma; any of them brightens a dish.
    • Dried citrus peel: 1 tsp dried for each 1 tbsp fresh zest. Milder and a little bitter.
    • Lemon or orange extract: About ¼ tsp extract for each 1 tsp zest, to taste. Strong citrus flavor, no texture.

    More for citrus zest

  • 2 cups all-purpose flour, spooned and leveled (250 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.

    All 4 swaps for all-purpose flour

  • 2 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.

    More for baking powder

  • ¼ 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 cup vegetable oil, 120 ml
    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.

    All 4 swaps for vegetable oil

  • 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.

  • ¾ cup plain yogurt, or Greek yogurt (180 g)
    Swaps for plain yogurt

    Instead of yogurt and Greek yogurt

    • Greek yogurt + milk: ⅔ cup Greek yogurt + ⅓ cup milk for each cup of regular. Same texture as regular yogurt, a bit tangier.
    • Sour cream: The same amount. Richer and less tangy.
    • Plant-based yogurt: The same amount, plain and unsweetened. Coconut yogurt is rich but tastes of coconut; soy yogurt is closest in protein.

  • ¼ cup milk, 60 ml
    Swaps for 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.

  • 2 tbsp lemon juice
    Swaps for lemon juice

    Instead of lemon juice

    • Lime juice: The same amount. A different, more floral aroma; works almost everywhere.
    • Bottled lemon juice: The same amount. More sour and flatter; fine in cooking and baking, less bright in dressings and drinks.
    • White wine vinegar or white vinegar: Half as much. Sharper, with no citrus aroma.

    More for lemon juice

  • 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 ½ cups blueberries, fresh, or frozen and not thawed (225 g)

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.
