tahini substitute
in cookies.
Tahini provides creamy richness and nutty flavor in Cookies. Its ground sesame paste suspends fat and solids in a stable emulsion, adding spread-limiting body to the dough; a substitute needs a comparable paste consistency so cookies don't flatten excessively or crack through the center when the fat separates during baking.

adjustment for this dish
Pesto's water content (from basil and oil emulsion) runs 15% higher than tahini, so the dough will spread into lace unless you chill scoops to 35°F for 60 minutes and add 1 tablespoon extra flour per cup. The savory profile demands a sugar cookie base, not chocolate — the cream of pesto with sugar stays golden but tastes of parmesan.
02
Cashew Butter
10.0best for cookies1 cup : 1 cup
Milder and creamier, works in dressings
10.0
adjustment for this dish
Cashew butter's higher sugar (9g per 2 tbsp vs tahini's 1g) caramelizes faster on a hot rack, so drop oven temp to 340°F and bake 10 minutes to crisp the edges without scorching the bottoms. Swap 1:1 by cup; the chew stays intact and the spread is slightly less since cashew has more solids than tahini.
03
Peanut Butter
7.5best for cookies1 tbsp : 1 tbsp
Thicker and sweeter; works in dressings and sauces, expect peanut flavor to dominate
7.5
adjustment for this dish
Peanut butter's 25% protein sets the dough firmer than tahini's 17%, producing a chewy, crisp-edged cookie with a denser center — cream 90 seconds with brown sugar, drop 2-tablespoon scoops, rest on parchment 30 minutes, bake 12 minutes at 350°F. Expect 10% less spread than tahini dough and a tender, golden finish.

Almond Butter
7.51 tbsp : 1 tbsp
Sesame-based; earthier, works in savory and sweet
7.5
adjustment for this dish
Almond butter is grainier than tahini (from skin solids), so strain it or use blanched if you want a smooth chew; swap 1:1 by tablespoon. The skins darken the edges faster on parchment, so pull at 10 minutes instead of 12. Rest 10 minutes on the sheet; the center sets to a tender, golden crisp.
05
Sunflower Seed Butter
7.51 cup : 1 cup
Nut-free, similar consistency and richness
7.5
adjustment for this dish
Sunflower seed butter turns dough green if creamed with baking soda — use baking powder only. Swap 1:1 by cup; chill scoops at 38°F for 45 minutes since sunflower fat melts 5°F lower than sesame and cookies otherwise spread thin. Drop on parchment, bake 11 minutes for crisp edges, rest on the rack 10 minutes.

technique for cookies
technique
Cookie dough with tahini will spread 15-20% more than a butter-only dough because sesame oil stays liquid below 60°F, so chill scoops on parchment for 45 minutes at 38°F before they ever hit a hot rack. Cream the tahini with brown sugar for 90 seconds on medium to aerate — it will look broken around second 30, then come together golden and glossy.
Drop 2-tablespoon portions 2 inches apart; they finish with crisp edges and a chewy center at 350°F for 11 minutes. Unlike brownies where tahini sits inside a contained pan, in cookies every gram of tahini widens the footprint and thins the center, so a 10-minute rest on the hot sheet before transferring to the rack lets the middle set without collapsing.
Unlike muffins where tahini is folded once into batter, here it must be creamed with sugar or the cookies bake pale and cakey instead of crisp-edged and chewy.
pitfalls to avoid
watch out
Don't scoop warm dough straight onto parchment — chill portioned balls at 38°F for 45 minutes or the cookies spread into lace and lose their chewy center.
watch out
Avoid creaming tahini with granulated sugar alone; use at least 50% brown sugar so the molasses holds moisture and the edges crisp to golden instead of baking pale.
watch out
Don't skip the 10-minute rest on the hot sheet after bake — tahini cookies set from the outside in, and moving them to the rack early collapses the tender middle.
watch out
Reduce flour by 2 tablespoons per cup when swapping tahini in, since sesame paste carries less water than butter and the dough otherwise bakes dry with cracked tops.
watch out
Don't drop portions closer than 2 inches apart; tahini dough doubles in footprint during bake and adjacent cookies fuse at the edges.
