Ingredients called for on the package, typically eggs, oil, and water or milk

¼ cup sour cream or plain Greek yogurt, optional
2 tablespoons melted butter, optional
Homemade Vanilla Buttercream Frosting
3 sticks unsalted butter, room temperature
4½ cups powdered sugar, sifted
1 tablespoon pure vanilla extract
3 to 5 tablespoons heavy cream
½ teaspoon kosher salt
For the Ombre Effect
Gel food coloring in your favorite color such as pink, blue, purple, peach, teal, or lavender
Step 1: Prepare the Cake Pans
Preheat the oven to 350°F. Grease and line four 6-inch cake pans or three 8-inch cake pans with parchment paper.
Step 2: Prepare Your Cake Batter
Prepare your preferred cake batter according to the selected option.
For scratch versions, whisk together the dry ingredients. Cream the butter and sugar until light and fluffy. Add the eggs one at a time followed by the vanilla. Alternate adding the dry ingredients and milk, then fold in the sour cream if using Option 1.
For the cake mix version, prepare according to the package directions while adding the vanilla, optional sour cream, and melted butter for extra richness.
Step 3: Create the Ombre Cake Layers
Divide the batter evenly into four bowls.
Leave one bowl plain.
Add a very small amount of gel food coloring to the second bowl to create a light shade.
Add additional coloring to the third bowl for a medium shade.
Add more coloring to the fourth bowl to create the darkest shade.
Each bowl should be a deeper version of the same color.
Step 4: Bake the Cake Layers
Pour each shade into its own prepared cake pan.
Bake for 28 to 35 minutes, or until a toothpick inserted into the center comes out clean.
Allow the cakes to cool in their pans for 10 minutes before transferring them to wire racks to cool completely.
Step 5: Prepare the Buttercream
Beat the butter until creamy.
Gradually mix in the powdered sugar.
Add the vanilla extract, salt, and enough heavy cream to create a smooth, spreadable frosting.
Continue beating for several minutes until light and fluffy.
Step 6: Assemble the Ombre Cake
Place the darkest cake layer on a serving plate.
Spread an even layer of buttercream over the top.
Add the medium-dark layer followed by more frosting.
Continue with the lighter layers, finishing with the lightest or white cake layer on top.
Step 7: Create the Ombre Buttercream
Divide the buttercream into four bowls.
Leave one bowl white.
Color the remaining bowls in increasingly darker shades of the same color.
Apply the darkest frosting around the bottom of the cake.
Spread the medium-dark frosting around the middle.
Apply the light frosting near the top.
Finish with white buttercream across the top edge.
Use a bench scraper or offset spatula to gently smooth the frosting together until the colors blend seamlessly into one another.
Step 8: Decorate the Cake
Pipe matching buttercream swirls around the top edge using the remaining frosting.
Decorate with fresh flowers, edible flowers, white chocolate curls, sprinkles, pearl dragees, or gold leaf for an elegant finish.
Step 9: Slice and Serve
Allow the cake to chill for 20 to 30 minutes before slicing.
Each slice will showcase beautiful graduated layers that perfectly match the ombre buttercream on the outside.
Use gel food coloring for the richest color without changing the consistency of the batter or frosting.
A digital kitchen scale helps divide both the batter and buttercream evenly.
Pastel shades create a soft, elegant appearance, while vibrant colors produce a bold celebration cake.
Chilling the crumb-coated cake before applying the final frosting makes decorating much easier.
Store the cake covered in the refrigerator for up to 5 days. Bring to room temperature before serving for the best texture and flavor.
