This ridiculously simple chocolate cake is my go-to move whenever a serious sweet tooth strikes or guests are on their way with little notice. No complicated steps or oddball ingredients here—just Oreos, milk, and baking powder get you an irresistibly fluffy, decadent dessert that tastes like you spent hours baking.
I still laugh thinking about the first time my nephew asked for seconds before I had even put the cake on the table. Every time I make it someone asks for the recipe in disbelief.
Ingredients
- Oreos: These cookies are both the structure and the chocolate flavor of the cake Choose original Oreos for classic results or experiment with different Oreo varieties for fun
- Whole Milk: This adds moisture and binds everything together Go for fresh whole milk for the fluffiest texture but any dairy or nut milk can work in a pinch
- Baking Powder: This is what helps your cake rise and gives it a nice crumb Double check that your baking powder is fresh for a good lift
Step-by-Step Instructions
- Crush the Oreos:
- Use a food processor or blender to pulse the Oreos into a fine crumb They should resemble potting soil with no big pieces because this creates a smooth batter and consistent bake
- Mix the Batter:
- In a medium bowl combine the Oreo crumbs with baking powder and whole milk Stir until the mixture is smooth and looks like a thick cake batter A little patience with mixing ensures no dry clumps
- Pour and Bake:
- Pour the batter into a greased baking dish or divide among small ramekins Smooth the top with a spatula for an even finish Bake at 350 degrees Fahrenheit for about fifteen minutes Check with a toothpick in the center when it comes out clean the cake is done
- Cool and Serve:
- Let the cake cool slightly before serving Enjoy straight from the ramekin or the baking dish To elevate it top with whipped cream a few crushed Oreos or a drizzle of chocolate ganache

I always look forward to the warm aroma that fills the kitchen as it bakes It reminds me that creativity and comfort are just a few simple ingredients away The best part might be handing a slice to someone who cannot believe there are only Oreos milk and baking powder inside
