Ingredients

For the Vanilla Cake:

1¼ cups (175 g) cake flour (or all-purpose flour)

1 tsp baking powder

½ tsp baking soda

½ tsp salt

¼ cup (57 g) unsalted butter, room temp

¾ cup (150 g) granulated sugar

3 tbsp neutral oil

2 large eggs, room temp

2 tsp vanilla bean paste or vanilla extract

⅓ cup (77 g) sour cream, room temp

⅓ cup (80 g) buttermilk (or milk), room temp

5 Oreo cookies, broken into pieces

For the Whipped Cream Cheese Frosting:

½ cup (60 g) powdered sugar

4 oz (113 g) cream cheese, room temp

3 tbsp black cocoa powder (or regular cocoa)

½ cup (60 g) powdered sugar (additional)

1 cup (237 ml) heavy whipping cream

1 tsp vanilla bean paste or extract

4 crushed Oreo cookies, for topping

Instructions

Make the Cake:

Preheat oven to 325°F (165°C). Line and grease an 8 or 9-inch round or square baking pan.

In a stand mixer, cream butter and sugar until light and fluffy (about 2 minutes). Add oil and eggs; beat another 2 minutes. Mix in vanilla and sour cream.

In a separate bowl, whisk together flour, baking powder, baking soda, and salt.

Add dry ingredients and milk in alternating parts to the butter mixture—beginning and ending with dry ingredients.

Gently fold in broken Oreo pieces.

Pour into the prepared pan and bake for 27–33 minutes, or until golden brown and a toothpick inserted comes out clean.

Cool the cake completely before frosting.

Make the Frosting:

In a small bowl, mix ½ cup powdered sugar, cream cheese, and cocoa powder until smooth.

In another bowl, whip heavy cream, ½ cup powdered sugar, and vanilla extract until stiff peaks form.

Fold the whipped cream into the cream cheese mixture. Leave a few streaks for visual texture, if desired.

Assemble:

Frost the cooled cake with whipped frosting.

Top with crushed Oreos just before serving.

Notes

Room temperature ingredients = fluffier, more even cake.

Use black cocoa for true Oreo flavor, but regular cocoa works too.

Bake and cool completely before frosting to prevent melting.

Lightly spoon and level flour for accuracy if not using a scale.
