Start by baking the cake layers. If you’re using a box cake mix, just follow the instructions on the box. I always like to swap out the water for milk to give the cake a richer texture, and I throw in a bit of vanilla extract for extra flavor. Once your batter is mixed, divide it evenly between your greased cake pans and pop them into the oven.

To check if the cakes are finished, gently insert a toothpick into the center of the cakes. If it comes out clean, they’re ready! This should take about 25 minutes, but baking times can vary depending on your oven. After they’ve baked, let them cool in the pans for about 10 minutes, then turn them out onto a wire rack to cool completely.

While the cakes cool, whip up your frosting. For the buttercream, beat the softened butter until smooth, then gradually add the powdered sugar, one cup at a time. You can add a splash of milk to get the perfect consistency—just make sure it’s spreadable but not too runny.

Once the frosting is nice and smooth, add a little vanilla extract for flavor, and a few drops of pink food coloring to give it that gorgeous Barbie pink shade. Mix it up until you get your desired color.

After your cakes have cooled, it's time to start putting everything together. Place the first cake layer on a cake stand or large plate. Spread a generous amount of frosting on top, covering it evenly.

Add the second cake layer on top, and now we’re going to do something called a crumb coat. Spread a thin layer of frosting over the entire cake to lock in the crumbs. After this, pop the cake into the fridge for about 10-15 minutes to let the crumb coat firm up.

Once the crumb coat is set, take the cake out and apply a thicker layer of frosting all over the cake. You can make it smooth or use a piping bag to add some pretty details, like rosettes or ruffles around the bottom.

Now comes the best part—adding Barbie! Wrap the lower half of your Barbie doll in plastic wrap to protect her, and carefully place her in the center of the cake. Make sure she’s standing up straight.

If Barbie is a little wobbly, you can use some extra frosting around her waist to hold her in place. Don’t stress if things get a little messy—it’s all part of the fun!

Now, let your creativity shine! You can decorate Barbie’s “dress” with more frosting or add fun touches like sprinkles, edible pearls, or glitter to make her sparkle. The more, the better!
