If you are searching for a showstopper dessert with hardly any effort this three ingredient Oreo cake will amaze you It transforms everyday cookies into a soft chocolaty treat that is just as perfect for a birthday as for an afternoon pick me up My family could not believe how easy it was and it has become our movie night staple
I first tried this when I wanted a wow factor cake but had almost nothing in the pantry My kids helped crunch the cookies and now it is our rainy day bake
Ingredients
- Oreo Cookies: make up both the chocolate and the creamy layers so the cake is rich and a little nostalgic Look for classic Oreos not double stuff or thins for best results
- Baking Powder: ensures the cake rises and gets a fluffy tender crumb Check that yours is fresh by looking for a recent date
- Milk: binds everything and creates a pourable batter Whole milk tastes best but any milk or non dairy alternative will work just fine
- Cooking Spray: helps the cake release cleanly from the pan Any neutral oil or softened butter also works
- Semi Sweet Chocolate Chips: add chocolate intensity to the optional ganache The best quality chips melt smoothly for glossy results
- Light Cream: provides richness to the ganache and blends beautifully with the chocolate Avoid heavy cream for this recipe since it will set too firmly
Step-by-Step Instructions
- Prepare Oven and Pan:
- Set your oven to three hundred fifty degrees Fahrenheit and allow it to preheat Line or grease a round or square nine inch cake pan with cooking spray making sure to coat all the edges so your cake does not stick
- Make the Oreo Batter:
- Add all twenty eight Oreos to a blender or food processor and pulse until only fine crumbs remain Transfer to a mixing bowl Stir in the baking powder making sure it is evenly dispersed Pour in the milk and whisk well The batter should look smooth with no lumps
- Bake the Cake:
- Pour the batter into your prepared pan smoothing the top Bake for twenty five to thirty minutes You will know it is done when a toothpick poked into the center comes out clean Let the cake cool in the pan fully before turning it out so it stays intact
- Prepare Ganache Optional:
- Warm the cream gently in a small saucepan over low heat until you see tiny bubbles around the edges but no boil Take it off the heat Add the chocolate chips and stir patiently until melted Smooth and shiny ganache should flow easily For extra thick ganache add more chips and stir again
- Decorate and Serve:
- Place the cooled cake on your favorite plate and pour the ganache right over letting it spill down the sides For an irresistible look scatter extra crushed Oreos or chocolate chips on top Let the ganache set a bit before slicing
