1 and 1/2 teaspoons baking soda
1 teaspoon salt
2 large eggs, room temperature
1 cup (240ml) whole milk, room temperature
1/2 cup (120ml) vegetable oil
2 teaspoons pure vanilla extract
1 cup (240ml) hot brewed coffee
10 Oreo cookies, roughly chopped
1 and 1/2 cups (340g) unsalted butter, softened (for buttercream)
4 cups (480g) powdered sugar
2 tablespoons instant coffee granules
2 tablespoons hot water
1/4 cup (60ml) heavy cream
1/2 teaspoon salt (for buttercream)
10 Oreo cookies, finely crushed (for buttercream)

Instructions

Prep and Preheat

Preheat oven to 350°F (175°C). Grease and flour two 8-inch round cake pans and line with parchment paper.

Make the Chocolate Oreo Cake

In a large bowl, sift together the flour, cocoa powder, sugar, baking powder, baking soda, and salt.
Whisk in eggs, milk, oil, and vanilla extract until smooth.
Pour in hot coffee and mix until just combined (batter will be thin).
Fold in chopped Oreos gently.
Divide batter evenly between prepared pans.
Bake for 28–32 minutes, or until a toothpick inserted in the center comes out clean.
Cool cakes in pans for 10 minutes, then transfer to wire racks to cool completely.

Make the Coffee Oreo Buttercream

Dissolve instant coffee granules in hot water; set aside to cool.
In a large bowl, beat butter on high speed until creamy and pale, about 3 minutes.
Gradually add powdered sugar, mixing on low and then on medium until fully combined.
Add dissolved coffee, heavy cream, and salt; beat until fluffy, 3–4 minutes.
Fold in finely crushed Oreos until just combined.

Assemble the Cake

Place one cake layer on your serving plate. Spread a thick layer of buttercream over the top.
Top with the second cake layer and frost the top and sides generously.
Decorate with extra Oreo cookies as desired.
Slice and indulge!

Notes

Make sure your cakes are completely cool before frosting to prevent the buttercream from melting.
For extra Oreo crunch, sprinkle chopped Oreos between cake layers.
If you don’t have instant coffee, strong brewed espresso can be used instead for the buttercream.

Variations

Mint Oreo Cake: Add 1/2 teaspoon mint extract to the batter and frosting for a refreshing twist.
Double Chocolate: Stir chocolate chips into the cake batter for extra richness.
Gluten-Free: Substitute a 1:1 gluten-free flour blend for the all-purpose flour.

Required Equipment

Two 8-inch round cake pans
Parchment paper
Mixing bowls
Electric mixer
Wire cooling racks
Offset spatula or butter knife

Storage Instructions

Store cake covered at room temperature for up to 2 days, or in the refrigerator for up to 5 days. For longer storage, wrap slices tightly and freeze for up to 2 months; thaw overnight in the fridge before serving.

Serving Recommendations

Pair your Oreo Cake with a fresh cup of coffee or a tall glass of cold milk. For special occasions, serve with a scoop of vanilla ice cream or a drizzle of warm chocolate sauce for extra decadence.

Pro Tips for the Best Oreo Cake

Use room temperature ingredients for a smoother, more even batter.
Chop Oreos just before folding into the batter to keep them crunchy.
Let the assembled cake rest in the fridge for 30 minutes before slicing for cleaner cuts.

FAQ

Can I make this cake ahead of time?: Yes! Both the cake layers and buttercream can be made one day in advance, stored separately, and assembled before serving.
What’s the best way to crush Oreos for buttercream?: Use a food processor for fine crumbs, or place cookies in a zip bag and crush with a rolling pin.
Can I use different pan sizes?: Absolutely! You can use two 9-inch pans (reduce baking time slightly), or turn it into cupcakes—start checking for doneness at 16–18 minutes.
