Homemade Mug Cookies (for When Your Sweet Tooth Strikes)

Have you ever had that late-night chocolate craving only to realize you didn’t have anything sweet to eat at the ready? (This was the motivation behind my 5 minute chocolate sauce) We’ve all been there, and I’ve got just the fix for you!

The ingredients are similar to a peanut butter chocolate chip cookie — unsalted butter, brown and white sugar, an egg yolk, vanilla extract, creamy peanut butter, milk, chocolate chips, and all-purpose flour except that I shrunk it down in size and cooked it in the microwave instead of the oven. (No preheating or greasing necessary!) I also omitted the baking powder and baking soda due to the fact we are cooking it in the microwave and for only a short period of time.

These peanut butter and chocolate chip cookies in a cup are so simple to make and will satisfy any sweet tooth. This is the perfect dessert for one! (Or make two or three to feed a crowd! Just prepare one cookie per mug.)

You can omit the chocolate chips if you’re in a strictly peanut butter mood!

How To Make a Mug Cookie with Peanut Butter and Chocolate Chips

  1. Melt 1 tablespoons butter in a microwave safe coffee mug.
  2. Add in both sugars and mix to combine. Mixture will be a bit runny that is fine.
  3. Add in the wet ingredients — egg yolk, peanut butter, and a drop of vanilla extract.
  4. Fold in flour. Consistency should be similar to a regular batch of cookies. If batter is too thin add a bit more flour.
  5. Mix in semi-sweet chocolate chips.
  6. Cook in the microwave for 45-60 seconds, and let stand for 2 minutes. The cookie will continue to cook as it cools.
  7. Serve with ice cream, and watch it melt into your cookie. Grab a spoon, dig in, and enjoy!

We do not recommend storing this microwave cookie because it only makes one serving (and, trust us, there won’t be any leftovers!). Just prepare fresh whenever the craving strikes.
