Single serving peanut butter cookie ingredients
The recipe calls for peanut butter, pure vanilla extract, flour, baking soda, salt, sweetener of choice, milk of choice, and optional ingredients like chocolate chips or chopped peanuts.
Flours that work include spelt, white, whole wheat pastry, oat (my favorite), and almond flour for a keto version. I do not recommend coconut flour here.
You can use any all purpose liquid or granulated sweetener, including pure maple syrup, agave, honey (not for vegans), brown sugar, white sugar, coconut sugar, or granulated erythritol or xylitol for a sugar free cookie.
Liquid sweeteners yield a more cakey cookie, while cookies made with granulated sugar have a more chewy texture.
Almond butter, cashew butter, macadamia nut butter, or nut free sunflower butter all work as peanut free alternatives.

How to make a peanut butter cookie for one
Preheat an oven or toaster oven to 350 degrees Fahrenheit.
If using natural peanut butter from the refrigerator, either let it sit out for a few hours or gently warm it until soft and easily stir-able.
Stir together the flour, salt, baking soda, optional chopped peanuts, and granulated sugar (if using). Then mix in the peanut butter, vanilla extract, milk of choice, and any liquid sweetener you might be using.
If using a dry sugar instead of a liquid one, slowly add in just a little extra milk to achieve a peanut butter cookie dough texture.
Form into one large cookie or two smaller cookie shapes. Place on a cookie tray, and bake for seven minutes. They should look a little underdone after this time. Let cool before handling, during which time the cookies will firm up considerably.
A few readers have reported success in a microwave, but I have not tried it yet here. If you prefer, I do have a chocolate chip recipe for Microwave Cookies.
Storing leftovers
The best and worst part about making a single serving cookie is that there are not likely to be any leftovers.
However, if you wish to save time and combine all of the peanut butter cookie ingredients the night before, you can store the unbaked cookie dough ball in a covered container in the fridge or freezer until ready to use.
Or if you have more willpower than I do, bake the cookie ahead of time. Then let it cool before enjoying the next day or freezing in an airtight container to enjoy within two months.
