Easy Apple Mug Cake Recipe
This cinnamon apple mug cake recipe came about when I was craving an autumn treat, but didn’t want leftovers. I had just made my Instant Pot Apple Butter, so I had a few extra apples in the fridge, and what better way to use fresh apple than in this single serve apple cake! No egg needed, just a few simple ingredients, and all the delicious apple cinnamon flavor I wanted!
How does cake in a mug work?
I know it seems too good to be true, but mug cakes are SO good and so easy! But what is the science behind mug cake? Well, microwave ovens work by exciting water molecules within the cake batter, which heat the batter and eventually evaporate. You’re left with a perfectly moist apple mug dessert, bursting with fresh apples, vanilla, and spices. For more on how this apple mug cake recipe works, check out this Popular Science article.
Apple Pie Mug Cake Ingredients
- melted butter – you’ll pop your butter into the mug to melt it in the microwave before adding the rest of the ingredients. I use salted butter for this recipe, but if you use unsalted, just add a couple pinches of salt.
- grated apple – I used a Gala apple for this apple pie mug cake. You’ll use a box grater to grate the apple, making it the perfect size to add apple flavor and moisture to this cake!
- light brown sugar – I love the flavor of brown sugar in this cake! It works so well with the vanilla and spices.
- pure vanilla extract – be sure to use a high-quality pure vanilla extract. Or better yet, check out my post on how to make vanilla extract at home with just 2 ingredients!
- lemon juice – brings out the tartness of the apples.
- milk – use whatever milk you like in this recipe — I use whole milk, but lowfat milk or a plant milk would work well.
- all-purpose flour – be sure to use a kitchen scale to measure by weight, or use the spoon-and-level method to measure by volume.
- baking powder – gives this mug cake its lift!
- apple pie spice – if you don’t have apple pie spice, then pumpkin pie spice would also work.
First, you’ll need a mug with at least a 16-ounce capacity. Then just use a fine-mesh sieve to sift in your dry ingredients, a fork or mini whisk to whip it all up and you’re ready to pop it in the microwave!
Tips and F.A.Q.
It’s definitely safe to eat mug cakes, assuming you cook them long enough so that they’re baked through. If the top of your apple pie mug cake is dried out, then it’s done cooking and ready to eat!
Yes they do! This easy apple mug cake is made with baking powder, which gives the cake a nice lift as it cooks in the microwave.
First of all, in this cinnamon apple mug cake we’re skipping the egg — it makes this mug cake easier to make and gives it the best texture. Instead of egg, we’re using baking powder for height and grated apples for moisture. Also, enjoying your mug cake right away (rather than saving for later) for the freshest flavor. Finally, top your mug cake with whipped cream or caramel sauce to make it even more decadent!
You may have added a little too much grated apple or milk. In this recipe, too much moisture weighs down the texture a bit. Stick with the amount of apple and milk listed in the recipe card below for the best apple mug dessert!
Definitely enjoy your mug cake warm! Once it’s out of the microwave, let it cool for a minute or two so that it’s not too hot. Or if you’re like me, you’ll be too eager and burn your tongue on the hot cake!
Yes you can — after storing the mug cake, covered, in the fridge, just heat it for 15-20 seconds to reheat!
Check your mug to see that it’s marked “microwave safe” — usually on the bottom. In general, ceramic mugs are a safe bet for this microwaved apple pie mug cake. It should also have at least a 16-ounce capacity to accommodate the rise of the cake.
