Description

This 3-Ingredient Oreo Cake is the easiest dessert you can make with minimal ingredients! With just Oreos, milk, and baking powder, you can create a rich, moist cake that’s perfect for any occasion. Top it off with a homemade ganache for extra indulgence, and you’ve got a dessert that’s sure to impress!


Ingredients

For the Cake:

28 OREO cookies (with filling)

1 teaspoon baking powder

1 cup milk

Cooking spray (for greasing the pan)

Optional Homemade Ganache:

½ cup light cream (10% M.F.)

1 ⅓ cups semi-sweet chocolate chips (add extra for a thicker ganache)


Instructions

  • Prepare the Oven and Pan:
    Preheat your oven to 350°F (175°C). Lightly grease a round or square cake pan with cooking spray.

  • Make the Cake Batter:
    Add 28 OREO cookies (with filling) to a blender or food processor and pulse until finely crushed. In a mixing bowl, combine the crushed Oreos with 1 teaspoon of baking powder and 1 cup of milk. Whisk until the batter is smooth.

  • Bake the Cake:
    Pour the batter into the prepared cake pan and spread it evenly. Bake for 25-30 minutes, or until a toothpick inserted into the center comes out clean. Let the cake cool completely in the pan.

  • Optional Homemade Ganache (for extra indulgence):

    • Heat the Cream: In a small saucepan, warm ½ cup light cream over low heat until it just begins to simmer (don’t let it boil).

    • Melt the Chocolate: Remove from heat, then add 1 ⅓ cups of semi-sweet chocolate chips. Stir until smooth. Add extra chocolate chips for a thicker ganache.

  • Decorate the Cake:
    Once the cake has cooled, pour the ganache over the top, letting it drip down the sides. Let the ganache set before slicing and serving.


Notes

Ganache Option: The ganache is optional but makes the cake even richer and more indulgent.

Customizing: Add crushed Oreos or chocolate chips to the batter for extra texture and flavor.

Storage: Keep the cake at room temperature for up to 2-3 days. The ganache may soften, so store in a cool place.
