Ingredients
Dry Ingredients
- 2 1/4 cups + 2 tbsp (309g) all-purpose flour
- 3/4 tsp baking soda
- 1 tbsp cocoa powder
- 3/4 tsp salt
Wet Ingredients and Mix-ins
- 3/4 cup (168g) unsalted butter, room temperature
- 1 cup (207g) sugar
- 1 large egg
- 1 tsp vanilla extract
- 2 tsp white vinegar
- 1 1/2 tbsp red food coloring (less than 1 ounce)
- 1 cup (169g) white chocolate chips (plus extra for topping)
Frosting
- 4 oz cream cheese, room temperature
- 3 tbsp butter, room temperature
- 2 cups (230g) powdered sugar
- 1/2 tsp vanilla extract
- Sprinkles for decoration
Instructions
- Preheat and prepare pan: Preheat your oven to 350 degrees Fahrenheit. Line the bottom of a 9-inch cake pan with parchment paper and grease the sides to prevent sticking.
- Mix dry ingredients: In a medium bowl, whisk together the flour, baking soda, cocoa powder, and salt. Set aside.
- Cream butter and sugar: In a mixing bowl, beat the unsalted butter and sugar together until light and fluffy, approximately 2 to 3 minutes.
- Add egg: Incorporate the large egg into the butter and sugar mixture until fully combined.
- Add flavorings and color: Mix in vanilla extract, white vinegar, and red food coloring until the mixture is uniformly colored and combined.
- Combine dry and wet ingredients: Gradually add the dry ingredients to the wet mixture and stir just until combined, careful not to overmix.
- Add white chocolate chips: Fold in the white chocolate chips gently. Reserve a few chips to press on top of the dough once in the pan if desired.
- Press dough into pan: Using an offset spatula, evenly press the slightly sticky dough into the prepared cake pan, smoothing the surface.
- Bake: Place the pan in the oven and bake for 18-20 minutes, or until the edges are set and the center appears matte.
- Cool: Remove the cookie cake from the oven and allow it to cool completely in the pan. Then transfer it to a serving plate.
- Prepare frosting: Beat the cream cheese and butter together until smooth and creamy.
- Add powdered sugar and vanilla: Gradually add 1 cup of powdered sugar to the cream cheese mixture and mix until combined. Then stir in vanilla extract.
- Finish frosting: Add the remaining powdered sugar and beat until the frosting is smooth and spreadable.
- Decorate: Pipe or spread the cream cheese frosting around the edges of the cooled cookie cake. Add sprinkles on top for decoration.
- Store and serve: Store the frosted cookie cake in an airtight container until ready to serve to maintain freshness.
Notes
- Make sure the butter and cream cheese are at room temperature for smooth mixing.
- Do not overbake; the center should look matte but not wet to avoid dryness.
- Using an offset spatula helps evenly press the sticky dough into the pan.
- White chocolate chips add sweetness and texture but can be replaced with regular chocolate chips if preferred.
- For vibrant red color, use gel or liquid red food coloring as specified.
- The vinegar helps enhance the red velvet flavor and works with baking soda to create tenderness.
- Store the cookie cake in an airtight container in the refrigerator for up to 3 days.
