How to make a brownie in a mug
- Cocoa powder (I use this one)
- Oil – vegetable or olive oil if that’s all you have
- Peanut butter (optional, great without it too)
- medium/large microwave safe mug
The reason why you need a mug a bit larger than a standard tea or coffee cup is it may overflow.
Mug cake no egg
Cooking time is short because it is just one (or two) serving really. If you’re looking for a dessert with no eggs necessary, this is the one to make!
- A dollop of whipped cream of vanilla ice cream on top can be added too.
- It’s pretty darn sweet though so I would first try as is. It’s to die for!
If you love this easy brownie in a mug recipe you could put together the dry ingredients in small baggies.
- Then use another “batch” on other nights.
- Write with a sharpie on the bag what wet ingredients you need so it’s quick when you’re ready to make it again.
Seriously, it is so easy that way. Just make a large batch of this brownie in a mug mixture but portioned out into ziplocs so it’s ready when you are.

Can you reheat a mug cake? Well to be honest I have never not finished the entire thing on the first go around.
If I don’t my husband will finish it off but I suppose you could cover with plastic wrap and then microwave for 10 seconds for the next go around.
Make sure you measure flour properly when measuring ingredients.
Peanut Butter Brownie in a Mug
- Add dry ingredients to mug and stir (use 12 oz. mug or larger because it will rise a bit).
- Add wet ingredients to mug and stir until mixed.
- Put tbsp. of peanut butter in middle of mix and push down a bit so it is submerged into brownie batter.
- Microwave for 60 seconds…done!!
- Note: if you allow it to cool for 5 minutes it will solidify more if you want it more cakier and less ooey gooey
