sunflower seed butter substitute
in brownies.
In Brownies, Sunflower Seed Butter provides the fat that creates tenderness and carries flavor throughout the dense, fudgy texture. A replacement must melt and behave similarly during cooking.

adjustment for this dish
Peanut butter contains no chlorogenic acid, so you can restore the full 1/2 tsp baking soda per 8-inch pan without fear of the fudgy center turning green on cool. Its oil content runs 50% versus seed butter's 55%, so add 1 tsp neutral oil per cup to keep the crackle top glossy and the edges tender through the pull.
02
Tahini

Nut-free, similar consistency and richness

adjustment for this dish
Tahini swaps 1:1 by cup but its sesame solids are drier than seed butter's, so whisk in an extra egg yolk per cup of tahini to restore the fudgy ribbon and prevent a crumbly square. Expect a pronounced nutty bitterness against the cocoa, and drop the sugar by 2 tbsp to keep the balance from swinging too savory at the center.

Almond Butter
10.01 tbsp : 1 tbsp
Nut-free; may turn green in baking (harmless)
10.0
adjustment for this dish
Almond butter is thicker and about 10% denser than sunflower seed butter, so thin with 1 tbsp warm water per cup before folding into the cocoa batter or the ribbon turns pasty. It browns faster in the oven, so pull the pan at 20 minutes instead of 22 to prevent the edges from crossing into bitter while the center stays glossy and tender.
technique for brownies
technique
Sunflower seed butter's chlorogenic acid reacts with baking soda at oven temperatures above 300F and turns the crumb green within 20 minutes of cooling, so drop the soda to 1/4 tsp per 8-inch square pan and lean on 1/2 tsp baking powder instead to keep the fudgy center brown. The oil content runs about 55% by weight versus dairy butter's 80%, meaning you should melt the seed butter with 2 tbsp extra neutral oil per cup before whisking it into the sugar-egg ribbon, otherwise the cocoa batter turns pasty and the crackle top never forms.
Stir until the ribbon falls off the whisk in a 3-second drizzle, not longer, since over-whisking inflates the batter into cakey territory. Unlike cookies where you want lateral spread across a sheet, brownies need the batter to hold a stiff mound in the pan so the edges set before the center, giving you that glossy top and tender pull from the middle square.
Pull at 325F when a toothpick shows wet crumbs at 22 minutes.
pitfalls to avoid
watch out
Avoid using more than 1/4 tsp baking soda per batch because the seed butter's chlorogenic acid will turn the fudgy center of each square bright green within 3 hours of cooling.
watch out
Don't over-whisk the egg-sugar ribbon past 90 seconds; the extra air pushes the crumb from fudgy toward cakey and kills the crackle top you want on the pan.
watch out
Skip melting the seed butter solo in the microwave for more than 20 seconds at a time or the oils separate and refuse to emulsify into the cocoa batter, leaving greasy edges.
watch out
Don't pull the pan before 22 minutes at 325F since the center needs wet-crumb doneness, not clean-pick doneness, to stay glossy and tender through the pull.
watch out
Avoid cutting the brownies within 2 hours of baking; the seed butter fat re-solidifies on cooling and slicing warm produces ragged edges rather than clean squares.
