Ingredients
- ¾ cup pecans, about 85 g
Swaps for pecans
Instead of nuts
- Another nut: The same amount. Pecans are sweeter and softer, walnuts slightly bitter, almonds firmer and milder.
- Toasted pumpkin or sunflower seeds: The same amount. Smaller and crunchier, with an earthy taste.
- Leave them out, or use chocolate chips or toasted oats: The same amount (or none). Leaving nuts out doesn't change how a batter bakes.

- 1 cup unsalted butter, softened (227 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 brown sugar, packed (160 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.
- 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.
- 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.
- 2 ¼ cups all-purpose flour, spooned and leveled (280 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.

Steps
Kid helper. A child can do steps 3, 4, 5, 6, 7, 9 and 11: no knife, no heat. Steps marked “Grown-up” use a knife or heat. Cooking with kids
- Heat the oven to 350°F (175°C). Spread the pecans on a sheet pan and350°F⏱ Toast pecans: 8 minGrown-up: heatuntil fragrant.
toast (how to toast)
Toast Heat nuts, seeds, spices or bread crumbs in a dry pan or oven until fragrant and lightly browned. 1. Spread them in a dry skillet over medium-low heat, or on a sheet pan at 350°F.2. Shake the pan or stir often.3. Watch and smell: the moment they smell nutty, they are close.4. Tip them onto a plate right away; the hot pan keeps cooking them. Done when: They are fragrant and a shade darker. Small seeds take 1 to 3 minutes; nuts in the oven 5 to 10. How to toast nuts, seeds, spices and bread: mistakes to avoid - Let the pecans cool, then⏱ Cool pecans: 10 minGrown-up: knife, heatthem finely on a cutting board.
chop (how to chop)
Chop Cut food into bite-size pieces that don't have to match exactly. 1. Cut a flat side on round food and lay it on that side so it can't roll.2. Slice the food into strips about as wide as the pieces you want.3. Turn the strips and cut across them.4. Rock the knife over any big pieces until they are about the same size. Done when: The pieces are close enough in size to cook in the same time, about ½ inch unless the recipe says otherwise. Safety: Keep the fingertips of your guiding hand curled under, knuckles toward the blade, and set the board on a damp towel so it can't slide.How to chop vegetables and herbs: mistakes to avoid - In a large bowl,⏱ Cream butter: 2 minKid stepthe butter, brown sugar, vanilla and salt on medium speed until creamy.
beat (how to beat)
Beat Mix hard and fast, by hand or with a mixer, to blend ingredients fully and add air. 1. Use a mixer on the speed the recipe gives, or a fork or whisk for a few eggs.2. Add eggs one at a time, beating until each disappears before the next.3. Stop and scrape the bowl and beaters now and then.4. Mix on low once flour goes in, just until combined. Done when: The mixture is smooth and even, with no streaks of yolk or white. Safety: Turn the mixer off before you scrape the bowl or reach in.How to beat eggs and batters: mistakes to avoid - Add the flour and mix on low speed until a soft dough forms.Kid step
- Stir in the chopped pecans.Kid step
- Divide the dough in half. On a sheet of parchment, shape each half into a log about 1 1/2 inches across and 8 inches long.Kid step
- Roll each log in the parchment and twist the ends. Refrigerate until very firm.⏱ Chill logs: 2 hrKid step
- Heat the oven to 350°F (175°C) and350°FGrown-up: heattwo sheet pans with parchment.
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 - Sprinkle the turbinado sugar on the counter. Unwrap the logs and roll them in it, pressing so it sticks.Kid step
- Grown-up: knifethe logs into 1/4-inch rounds with a sharp knife, turning the log a little after each cut so it stays round.
Slice (how to slice)
Slice Cut food into flat pieces of the same thickness. 1. Give round food a flat side to sit on.2. Hold it with your fingertips curled under.3. Cut with long strokes, pushing the knife forward and down rather than straight down.4. Move your guiding hand back the same distance each time so every slice matches. Done when: The slices are even. For meat, slicing across the grain (across the lines of muscle) gives the tenderest bite. Safety: Keep the fingertips of your guiding hand curled under, knuckles toward the blade, and set the board on a damp towel so it can't slide. Slice hot roasts on a board with a groove for the juices.How to slice evenly: mistakes to avoid - Set the rounds on the pans 1 inch apart.Kid step
- Bake until the edges are golden.350°F⏱ Bake: 13 minGrown-up: heat
