Here you are, miss H, the world's easiest, and most adaptable, cookie recipe.
1 cup peanut butter, creamy or crunchy
3/4 cup light brown sugar, packed
1 egg
1 tsp vanilla
1 tsp baking soda
Whip first four ingredients in a mixer on medium until creamed( no longer grainy )
Add baking soda and mix well
Scoop 1 tbsp balls 2 in apart onto baking sheet, flatten with fork
Chill 2 hours (very important)
Bake at 350 for about ten mins, rotate tray at halfway point
Let cool on tray until manageable
For the more health concious, use natural peanut butter + 1/2 tsp salt and replace brown sugar with coconut sugar.
For vegans replace egg with a flax egg (1 tbsp ground flax seed + 3 tbsp water combined and set for 15 mins)
If doing the vegan version, do not chill dough
Other nut butters may be substituted but the texture will be hit or miss, depending on fat content.
I some times roll the scooped balls in sugar or cinnamon sugar before baking or add 1/2 cup chopped, salted, roasted peanuts
Experiment, have fun, enjoy.
