Raspberry Oat Crumble Bars

• Oat crumb
• 1 ¼ cups all-purpose flour, spooned and leveled (155 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.

• ⅔ cup brown sugar, packed (140 g)
  Swaps for 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.

• 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.

• 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.

• 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.

• ¾ cup unsalted butter, melted (170 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.

• Raspberry filling
• 2 cups raspberries, fresh or frozen, not thawed (250 g)
• ¼ cup granulated sugar, 50 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.

• 1 tbsp cornstarch
  Swaps for cornstarch

  • All-purpose flour: 2 tbsp flour for each 1 tbsp cornstarch. Sauces turn cloudy instead of glossy and a bit heavier.
  • Arrowroot: The same amount. Very clear and glossy; can turn slimy in dairy sauces.
  • Potato starch: The same amount. Thickens fast with a clear gloss; don't boil it long.

• 1 tbsp lemon juice
  Swaps for lemon juice

  Instead of lemon juice

  • Lime juice: The same amount. A different, more floral aroma; works almost everywhere.

  • White wine vinegar or white vinegar: Half as much. Sharper, with no citrus aroma.
