There seem to be hundreds of “mug cake” recipes floating around the internet lately…

…and with good reason.

A single-serving cake that’s easy to prepare is genius.

Most of the mug-cake recipes I’ve seen call for refined flours and sugars, and are then microwaved for a quick treat. That may sound appealing to some, but I felt like an upgrade was in order–> one that doesn’t sacrifice ease or flavor.

This particular “mug cake” uses only a banana for sweetness, with no added flours or sugars. The result is a truly delicious, and guilt-free treat!

Peanut Butter Banana Mug Cake

serves 1

Ingredients:

1 very ripe banana (with brown spots!)

2 Tablespoons natural peanut butter, or nut butter of choice

1 whole egg

1/4 teaspoon baking soda

dash of cinnamon (optional)

Directions:

If using an oven, preheat to 350F.

Combine all of the ingredients into a mug, and mix until relatively smooth.

Bake at 350F for 30-35 minutes, until the top is golden brown and the center is firm.

Allow to cool for 5 minutes, then dig in!

Note: Because I don’t own a microwave, the oven is my preferred method for baking. I think it’s worth the wait, but of course, if you prefer the microwave, please feel free to use it–> I’d guess about 60 seconds would do the trick, but use your best intuition, as microwaves vary. (And please let me know how it works for you!)
