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.

Swaps for creamy peanut butter
Instead of peanut butter
- Sunflower seed butter: The same amount. Earthier and a little sweeter.
- Almond or cashew butter: The same amount. Milder and less salty (add a pinch of salt).
- Soy nut butter: The same amount. Close in taste and texture; contains soy.

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.
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.
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.

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.
Step 1 of 10
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.

Measure the peanut butter and vanilla into a bowl and set it next to the stove. The last steps move fast.
Step 3 of 10
In a heavy saucepan, stir the sugar, milk, 2 tablespoons butter and salt over medium heat until the sugar dissolves and the mixture comes to a .
boil (how to boil)
Boil Heat liquid until big bubbles rise and break all over the surface. 1. Use a pot big enough that the water fills it no more than three quarters.2. Cover it to boil faster, over high heat.3. Salt pasta or vegetable water once it boils.4. Add the food, stir, and bring it back to a boil before you start timing. Done when: A rolling boil keeps bubbling hard even when you stir. Safety: Turn pot handles toward the back of the stove, and drain pasta into a colander in the sink, pouring away from you. Steam burns fast: lift lids and foil away from your face, tipping the far edge up first.How to boil water for pasta and vegetables: mistakes to avoidStep 4 of 10
Clip a candy thermometer to the side of the pan so the tip is in the syrup but not touching the bottom.
