These gluten free and keto flourless peanut butter chocolate chunk cookies are definitely some of the easiest, yet tastiest, low carb cookies you could possibly whip up!
Cream butter in a large bowl with an electric mixer. Add in sweetener and continue to beat until light, fluffy and thoroughly mixed.
Mix In vanilla extract, baking soda and salt. Add egg and mix until just incorporated. The mixture will appear slightly 'broken' (i.e. not thoroughly smooth). Mix in peanut butter and beat until thoroughly incorporated. If your mixture is too runny now (ours was), wait to add the chocolate chunks post chilling (or they'll sink to the bottom..!).
Cover with cling film and refrigerate for 1 hour. Preheat oven to 350°F/180°C.
Using an ice cream scoop or large spoon, scoop out the dough. Place in a baking mat or parchment paper-lined baking tray. Add in chocolate chunks and flatten slightly (see pictures for reference). Freeze for 15 minutes prior to baking.
Bake for 8-10 minutes (we did 7), until they just begin to brown around the edges (but be sure to not let them brown!). Sprinkle with flakey sea salt (optional). They'll be very fragile post bake, particularly if you used xylitol.
Allow to cool completely before digging (seriously, the taste is so much better!), and store in an airtight container for 4-5 days. Though feel free to freeze the shaped dough and bake straight from the freezer (adding a few minutes to baking time).
*See section on sweeteners for deets and possible subs.
**In terms of the peanut butter, unless you go the homemade route, you want to purchase the variety that is fairly liquid at room temperature. Yes, the one were the oil separates if you leave it out unstirred for too long! You see, any other variety has had the peanut oil drained to keep it solid...! And if you're keto, this means that they've cheated you out of the fat, and automatically upped your protein and carb ratios. Plus, it may yield dry cookies (because they've removed a bunch of the natural fat...).
Please note that nutrition facts were calculated using natural homemade peanut butter (i.e. peanuts processed until smooth in the food processor!).
Also note that the chocolate is not included in the nutrition facts (values vary widely). But if you use a bar of Lily's dark chocolate, add roughly 0.75g net carbs per cookie (so each cookie would be roughly 1.75g net carbs).
