I've been baking my super fast 4 ingredient peanut butter chocolate chip cookies quite a bit now, and starting to experiment. Some day I want to try a half batch with tahini and see how they turn out. These would be a good recipe for gluten free folks as the main ingredients are nuts, eggs and sugar.
1 C brown sugar
1 C nut butter (peanut butter, almond butter etc.)
2 TB sesame seeds, or sunflower seeds
1/2 C chocolate chips
1 tea vanilla extract
Bake in small cookie shapes in 350 F oven for 8-12 minutes. They will look undone when you take them out of the oven, but leave them on the cookie sheet to finish cooking outside the oven.
