What changes when you swap peanut butter for sunflower seed butter
Swap sunflower seed butter for peanut butter at a 1:1 ratio and the cookie holds its shape, but a chlorophyll-acid reaction with baking soda can turn the crumb a startling moss-green within hours of baking. The flavour runs earthier and less sweet, since sunflower butter rarely carries the added sugar that stabilises commercial peanut butter, so a flourless three-ingredient peanut butter cookie reads more savoury and slightly bitter on the back palate.
- Drop baking soda to 1/4 tsp per cup of sunflower butter or swap to baking powder entirely — this prevents the harmless but unappetising green tint that shows up 4-12 hours after baking.
- Add 1-2 tbsp brown sugar per cup to compensate for sunflower butter's lower added-sugar content, especially in classic peanut butter blossoms or no-bake oat bars.
- Fat content sits around 55% versus peanut butter's 50%, so cookies spread slightly more — chill the dough 30 minutes to keep the rounds from going slack on the sheet.
