Ingredient Notes:

Now let’s talk about just some of the ingredients that are in this Oreo single-serve mug cake.

Flour, sugar, baking powder and salt: These are the dry ingredients you’ll need. This mug cake is essentially a ‘scratch’ cake, but it doesn’t take much of each ingredient and it comes together really quickly.

Butter: Butter just makes everything better and it’s really best if you have real butter and not margarine.

Oil, milk, and vanilla extract: These are the liquid ingredients that will be mixed in with the dry. These will make the cake moist and add flavor.

Oreos: You only need a couple of Oreos for this cake and if you like Golden Oreos more, go for it.

Butter, confectioner’s sugar, vanilla, milk: This mug cake includes a glaze. You’ll just mix all these ingredients together and drizzle the glaze onto the warm cake. It’s optional, but it’s so good and really worth the effort.

How to Make this Mug Cake:

Let’s talk about how to an Oreo mug cake. (The printable instructions are in the recipe card below.)

Step 1:

Add the Oreos to a ziplock bag and smash them up with either a meat mallet or a rolling pin to crush up the cookies. Set the bag aside.

Step 5:

Add the crushed Oreos to the mug and mix. Make sure to reserve a small amount of the Oreos to sprinkle on top of the baked mug cake.

Step 6:

Now, microwave the mug for about 45 seconds. Let it sit in the microwave for 1 minute and then test it to see if the cake is set and a little firm to the touch on the top.

If not firm, microwave for another 10 seconds and test again. Try not to overbake and err on the side of the lower baking time when starting out. (Microwaves will vary, so the exact bake time will vary.)

Once the cake is done, let it sit in the microwave for 1 minute while you make the glaze.

Tips & FAQs:

What type of butter should I use?

It’s best to use real butter instead of margarine. Real butter gives the best flavor. You can use either unsalted or salted butter.

Do I have to add the baking powder?

It’s best if you can as it will help the cake batter rise and turn out fluffy.

Can I use any cookies or do I have to use Oreos?

You can use any cookie you like. You can use Golden Oreos or any other cookie really.

Tip for microwaving the mug cake:

After microwaving for about 45 seconds, make sure to let it sit in the microwave for 1 minute before testing it. The cake will continue to bake a little in the mug.
When you test it, just press your finger to the top to see if the cake is set and a little firm to the touch on the top. If it’s not, microwave for only another 10 seconds and test again. Be careful about overbaking as this will dry out the cake and it can turn hard.

My mug cake came out too hard or chewy:

It’s possible that it was microwaved for too long. Try again, but for less time.

My mug cake came out raw in the middle:

The cake probably wasn’t microwaved long enough. Try again, but microwave for a bit longer.

Can’t you just tell me exactly how long to bake this in the microwave?

It’s really hard to do that because there are so many different types of microwaves with different amounts of power. The best advice I can give you is to start with 45 seconds and go from there.

Can this mug cake be made ahead of time?

It can, but it may get too firm if it sits too long. If you do decide to make it and eat it later, just make sure to cover it well with plastic wrap, then when you’re ready to eat, take the plastic wrap off and microwave for maybe 15-20 seconds to warm it up.

What’s the best way to serve/eat this cake?

This mug cake is best eaten warm, just a few minutes after it’s baked in the microwave.

What can be added to this mug cake?

You could add chocolate chips to this cake, or drizzle chocolate syrup on top.

How can I tell when this mug cake is done baking?

This cake is done baking when it’s firm to the touch on the top.
