Let's talk real butter
There are a few key ingredients in this recipe that are non-negotiable, one of those being butter! This recipe calls for 3 tablespoons of salted butter for one mug cake. But, it has to be real butter. For the best (and most delicious) results, avoid substituting oil or margarine!
Real butter is truly the only way to go. Butter not only adds moisture to the cake, but it also makes the cake tender and adds lots of flavor! While oil and margarine also add moisture, you won't get the same fluffy, cakey, flavorful results as you will with butter! And don't forget to use salted butter to help balance out the sweetness!

How to make an apple mug cake
Making an apple mug cake is quite simple. Here's an overview.
- Caramelize the apples. Add butter, spices, apples, and brown sugar to a mug and microwave for about 30 seconds to soften the apples and create a caramel-like sauce.
- Mix up the batter. In a small bowl, mix together the batter ingredients, then pour into the mug over the caramelized apples.
- Finish with more apple slices. Top the batter with the remaining apple slices, spices, brown sugar, and butter.
- Microwave the cake. Microwave for 1 minute 30 seconds to 2 minutes, or until the cake is puffy and set.
- Serve. Enjoy the cake while it's still warm with a drizzle of caramel sauce and a scoop of vanilla ice cream.

Tips & Tricks
- Don't over-mix the cake batter. Once the flour is added, you only want to mix the batter until the flour is just combined. Some small lumps of flour are OK. Over-mixing gluten will cause the cake to become chewy.
- Don't overcook the cake. It's best to check the cake as it cooks to make sure you aren't overcooking it, which can cause the cake to become dense.
- Use lots of butter. Butter not only keeps the cake nice and moist, but it also adds delicious flavor.
- Use more or less apples. Feel free to adjust the amount of apples to your personal preference!
Frequently asked questions
Why are some mug cakes chewy?
Just like a cake made in the oven, mug cakes can become chewy when the cake batter is overmixed or when the cake is overcooked. Overworking the gluten makes for a tough and chewy cake, so once you add the flour, mix until just combined.
What makes a mug cake rise?
When it comes to mug cake, all you need is a little baking powder to make the cake rise. No eggs are needed.
How to cut apples for apple mug cake.
Leave the skins on, cut out the core, and thinly slice the apples into wedges. About 4-6 slices per quarter apple. You don't want slices that are too thick because then they won't cook well.
Are microwave mug cakes safe to eat?
Yes! The microwave fully cooks the cake, and this recipe doesn't call for any eggs, so there's no need to worry!
Are mug cakes supposed to be gooey?
I prefer apple mug cakes fully cooked, but you can certainly reduce the cook time by about 30 seconds for a gooey center.
