❤️ Why I Love This Recipe

I love how simple this 3-Ingredient Oreo Cake is.

With just three ingredients, I can create a delicious dessert that looks and tastes sophisticated.

It’s perfect for all skill levels and requires minimal equipment.

I can make the recipe in an air fryer or microwave, making it quick and versatile.

The rich, chocolatey Oreo flavor is a dream for Oreo lovers like me.

The cake is moist and soft, with a lovely crumb.

I always add the optional ganache frosting because the melted chocolate and heavy cream make a ridiculously good topping that elevates the cake even more.

🛒 Ingredients You’ll Need

You won’t find an easier recipe with only three simple ingredients in the cake itself.

• Oreo cookies: I use a 14-ounce package of Oreo cookies in this cake recipe. It will work with any Oreo flavor, but I don’t recommend the Double Stuffed Oreos in this recipe.
• Milk: I use whole milk, but you could use 2% milk or non-dairy milk, such as almond milk.
• Baking powder: Baking powder is essential in this recipe because it helps give the cake a soft and tender texture.

If you are making the optional chocolate ganache for the topping, you will need two additional ingredients.

• Chocolate bar: I use a Baker’s brand chocolate bar made for baking. You can find these in the baking aisle of any grocery store. I don’t recommend Hershey’s chocolate bars from the candy aisle, but you could use semi-sweet chocolate chips.
• Heavy cream: Heavy cream or heavy whipping cream are best for making a rich chocolate ganache.

👨🏻‍🍳 How to Make Oreo Cake With Only 3 Ingredients

Here is a basic overview; the full Oreo Cake recipe instructions are in the recipe card below.

1. Make the cake batter: Mix together the Oreo crumbs, milk and baking powder in a medium bowl then pour it into your greased pan.
2. Cook the cake: Cook your cake using either the air fryer method or the microwave instructions. The cake is done when a toothpick inserted into the center comes out clean.
3. Let it cool: Let the cake cool before slicing, topping, or serving.

If making the ganache, you will need a few additional steps.

1. Chop up the chocolate: Finely chop the chocolate bar or break it apart so that it will melt easily.
2. Heat the heavy cream: A few seconds in the microwave will get the heavy cream steaming hot.
3. Pour over the cream then wait: Pour the hot cream over the chocolate and wait for it to melt.
4. Stir the ganache: Gently stir the ganache until it starts to thicken.
5. Pour over the cake: Spoon or pour the ganache over the cake and let it drip down the sides until it is completely covering the cake.

🔑 Key to Success #1 – Finely Crush the Oreos, Cream and All

This easy Oreo cake is made with three simple ingredients – Oreo cookies, milk, and baking powder.

And we’re using the whole Oreo, including the cream.

If you have a food processor, this is the perfect opportunity to use it because you want to grind the Oreo cookies as finely as possible so that your cake will have a smooth crumb.

You can throw the whole cookies into the food processor.

You do not need to separate the cream filling from the cookies before crushing or grinding them.

If you don’t have a food processor, you can place the cookies into a plastic baggie and crush them with a rolling pin or a heavy-bottomed pan.

Just keep in mind that the cookies need to be fine crumbs before you add the remaining two ingredients.

🔑 Key to Success #2 – Cook in Air Fryer or Microwave

This easy cake doesn’t even need an oven!

You can cook it in the air fryer or in the microwave in just about 30 minutes.

Pour the cookie crumbs into a mixing bowl then add in the baking powder and milk.

Stir the batter until it is completely combined.

The batter will be thin and this is okay.

If cooking in an air fryer, preheat the air fryer to 320 degrees F and grease a heat-safe baking dish that is approximately 6 inches in diameter.

You can also cook this cake in the microwave, but be sure to use a microwave-safe dish that is about 6 inches wide.

A 6-inch silicone cake pan (linked below) would be perfect for this recipe.

The cook time is similar for both methods.

Air fry or microwave (on high power) for 15 minutes then turn the pan 90 degrees and cook another 10-15 minutes.

All microwaves and air fryers cook a little differently so continue cooking until a toothpick inserted into the center of the cake comes out clean.

🔑 Key to Success #3 – Pour the Chocolate Ganache Over the Top

Wow, wow! Doesn’t that rich chocolate ganache look divine?

This simple ganache is made with only two ingredients. The first ingredient is a semi-sweet baking chocolate bar.

Not the chocolate bars in the candy aisle. Look in the baking aisle for baking chocolate bars. They are normally located close to the chocolate chips.

Before you unwrap the chocolate bar, use a heavy-bottom saucepan or a rolling pin to break up the chocolate bar into tiny bits.

Breaking up the chocolate bar will ensure that it melts quickly and evenly. And since you are doing this in the wrapper, you won’t end up with a big mess.

In a microwave-safe bowl, heat the heavy cream for 30 seconds. Check it to see if it’s hot and steaming. If not, heat for another 20-30 seconds until hot.

Remove the cream from the microwave and add in the chopped chocolate bar.

Make sure the cream is completely covering the chocolate then just walk away and let it sit for about 5 minutes to allow the chocolate to melt.

Stir the mixture until the chocolate is smooth then let it sit uncovered for about 15-30 minutes until it is starting to thicken.

Once it has thickened, pour the ganache over the cake and allow it to drip down the edges.

Troubleshooting Techniques

Even though this recipe is super simple, you might have a few questions or run into some issues. Here are some common points of concern and how to tackle them:

Why is my cake dense or not rising?

If your cake turns out denser than expected or doesn’t rise much, make sure you’re using fresh baking powder.

Also, ensure that you crush the Oreos finely; large chunks might affect the batter’s consistency and overall rise.

Can I use a different size pan?

Yes, you can use a different size pan, but keep in mind that the cooking time will vary.

A larger pan will result in a thinner cake and may cook faster, while a smaller pan will yield a thicker cake that might require more cooking time.

Adjust accordingly and always do the toothpick test to check doneness.

Is there a way to make this cake gluten-free?

Yes, you can make a gluten-free version by using gluten-free Oreo cookies and ensuring that your baking powder is also gluten-free. The rest of the ingredients are naturally gluten-free, making this a straightforward swap.

Can I make this cake in a microwave?

Absolutely! If you prefer or don’t have an air fryer, you can make this cake in a microwave. Pour the batter into a microwave-safe mug or bowl and microwave on high for 1-2 minutes, or until a toothpick inserted in the center comes out clean.

Recipe Variations

One of the best things about this recipe is how easily you can make it your own. Here are a few ideas to add a personal touch or exciting variation:

Flavor Twists

Consider adding a teaspoon of vanilla extract or a pinch of cinnamon to the batter for an added layer of flavor. You can also mix in some instant coffee granules to give it a mocha twist.

Layered Delight

For a more festive presentation, you can double the recipe and create a layered cake. Spread a layer of ganache between the two cakes and on the top for a show-stopping dessert.

Frosting Fun

While the ganache is fabulous, you can switch it up with other frostings like cream cheese icing, peanut butter frosting, or even a simple powdered sugar glaze.

Kid-Friendly Version

Invite the kids to help by letting them crush the Oreos and mix the batter. You can also let them decorate the cake with colorful sprinkles, candy pieces, or edible glitter for a fun and engaging family activity.

Storing and Reheating

Here’s how to keep your cake fresh and delicious, and the best ways to reheat it if you have leftovers:

Storing

Store any leftovers in an airtight container at room temperature for up to three days. If you decide to refrigerate, the cake can last up to a week. Just make sure to bring it to room temperature before serving so it retains its softness.

Reheating

To enjoy that just-baked warmth, gently reheat individual slices in the microwave for 10-15 seconds. This will soften the cake and bring back its fresh-out-of-the-oven feel.
