When you’re in the mood for a sweet treat but you don’t want to spend a lot of time baking or want to make a full batch, guess what? You can still have a from-scratch treat with just a few easy ingredients and a quick zap in the microwave!

This month has thrown us all for a loop, friends. First off, right around New Year’s, we all came down with COVID. Or let me say, my husband and son tested positive and otherwise didn’t notice, and I tested positive and felt like an elephant sat on me. Aches and pains in the joints, headache, nausea. Yuck.

Fortunately, the big symptoms only lasted about 48 hours for me. I know that’s not always the case and we’re all feeling extremely lucky. But what did persist was exhaustion. I’ve still been able to work without missing a beat {hooray for remote work and taking the occasional meeting sprawled on the couch with my laptop}, but otherwise, I’ve been infusing my paycheck into the sharing economy to summon up food, groceries, and supplies. Thank you, remote work, and thank you, Instacart and DoorDash.

As soon as I felt better, though, I started cooking again. But I also started looking for things to make that were delicious and low effort, not just for my own tiredness but in the hopes I could share a few recipes that would give some comfort without a lot of work.

So I thought back to college. We lived in historic dorms where we couldn’t have appliances or ovens, but we usually had a common room with a fridge and a microwave. So we learned how to make a lot of really easy single-serve things in the microwave, usually in a coffee mug – like the breakfast sandwich I shared a while back. Or these coffee mug brownies I’m going to share with you today!

Yep, you can make this delicious fudgy treat with just a few ingredients and a microwave – which can be a marvelous kitchen assistant if you let it. It’s not just for reheating leftovers!

This super fudgy super soft super delicious brownie recipe is made for one, but you can make as many one-size recipes as you want in different mugs, and just rotate them through the microwave. I recommend using a 10-oz or microwave safe ceramic mug, which makes sure it will cook just perfectly.

Load it up at the end with a nice scoop of ice cream and you have the perfect TV time treat, and no need to change out of those pajamas. That you might have worn to the virtual office anyway {no judging here}.

  • 1 10 oz ceramic mug
  • Microwave


  • 3 tbsp butter
  • 3 tbsp light brown sugar packed
  • 3 tbsp whole milk
  • 1/2 tsp vanilla extract
  • 1/4 cup all-purpose flour
  • 2 tbsp cocoa powder
  • 1/8 tsp salt
  • 1 tbsp miniature chocolate chips optional


  • Place the butter in a 10-oz ceramic microwave safe mug. Microwave until fully melted and bubbling, about 20 seconds. Swirl to coat the mug with melted butter, and then pour the remaining butter in a small bowl.
  • Whisk 3 tbsp packed brown sugar, 3 tbsp milk, and 1/2 tsp vanilla extract together in the butter bowl until smooth.
  • Add 1/4 cup all-purpose flour, 2 tbsp cocoa powder, and 1/8 tsp salt (a pinch) and stir until smooth again.
  • Fold in the chocolate chips if you're using them.
  • Scrape the batter into the mug. Microwave for about 1 minute. The brownie is ready when the center is slightly gooey and the edges spring back when pressed. If not ready, keep cooking for 15 second increments until you get to the right amount of doneness.


These are awesome when served with ice cream! They also go great with your favorite Cabernet Sauvignon. A dry red wine helps bring out all the great flavor and sweetness in the chocolate, but also stands up to those same tastes!
