Elegant Ombre Wedding Cake with Oreo Filling

Preheat your oven to 180 degrees Celsius (350 degrees Fahrenheit). Grease and flour four round cake pans with diameters of 28, 22, 18, and 14 centimeters (11, 9, 7, and 5.5 inches).

In a large mixing bowl, cream together the softened butter and granulated sugar until the mixture is light and fluffy. Add the eggs one at a time, ensuring each is fully incorporated before adding the next.

Mix the milk and vanilla extract, then slowly add this liquid to the butter-sugar mixture. Combine the flour and baking powder in a separate bowl, then gradually add to the wet ingredients, mixing until just combined. Distribute the batter evenly between the prepared cake pans.

Bake for 25-30 minutes, or until a toothpick inserted in the center comes out clean. Allow the cakes to cool in their pans for 10-15 minutes before transferring them to a wire rack to cool completely.

In a mixing bowl, beat together the softened cream cheese and powdered sugar until smooth. Gradually add the crushed Oreo cookies and mix until combined. This will create a rich, decadent filling for your cake.

In a large mixing bowl, whip the softened butter until creamy. Gradually incorporate the powdered sugar until the mixture is smooth and fluffy. Pour in the heavy cream and mix until well combined. This frosting will be used to both frost your cake and create the ombre effect.

Add food coloring to separate portions of the frosting to achieve your desired ombre effect. Start with a light shade and gradually deepen the color.

Once the cake layers are completely cooled, place the largest layer on a serving plate or cake stand. Spread a layer of the Oreo filling on top before adding the next cake layer. Repeat this process until all layers are stacked, finishing with the smallest layer on top.

Use the prepared frosting to cover the entire cake evenly. For the ombre effect, start with the darkest shade at the bottom and work your way to the lightest at the top. Smooth the sides as desired for a polished finish.

Finish off your beautiful cake with any additional decorations, such as edible flowers or toppers. Consider adding some crushed Oreos on top for an extra touch. Enjoy your stunning ombre wedding cake at your next celebration!
