Ingredients

To nail this Birthday Cake Aesthetic, you need the right foundation. Here is what you need to gather before you start baking.

For the Cake Layers

  • ¾ cup unsalted butter (softened)
  • ½ cup vegetable oil
  • 1 ½ cups granulated sugar
  • ¼ teaspoon sea salt
  • 6 large egg whites (room temperature)
  • 1 tablespoon pure vanilla extract
  • 1 tablespoon vinegar (white or apple cider vinegar)
  • ¼ teaspoon pink gel food coloring
  • 3 cups cake flour (345g)
  • 2 teaspoons baking powder
  • ½ teaspoon baking soda
  • 1 ¼ cup buttermilk (room temperature)

For the Cream Cheese Frosting

  • 2 cups butter (softened)
  • ¼ teaspoon sea salt
  • 6 to 7 cups powdered sugar
  • 8 oz cream cheese (softened for 10 minutes at room temperature)
  • 1 tablespoon pure vanilla extract
  • Pink gel food coloring
  • Red gel food coloring
  • Edible glitter spray (optional)

Step-By-Step Instructions

Creating Pretty Birthday Cakes is all about patience and following the process. Let us break this down so you can get that perfect bakery finish.

Step 1: Prepare the Pans and Batter Base

Start by preheating your oven to 355°F (180°C). You want to grease three 8 inch round baking pans with a little bit of cold butter. Line the bottoms with rounds of parchment paper to ensure the cakes come out perfectly smooth. In a large bowl or stand mixer, combine your softened butter, vegetable oil, granulated sugar, and sea salt. Beat this mixture with an electric mixer until it has lightened significantly in color and increased in volume. This step builds the structure for your Birthday Cake Aesthetic.

Step 2: Incorporate Eggs and Color

Scrape down the sides of your bowl. Add half of the egg whites and blend well, then add the rest of the egg whites and blend again. Continue beating until the mixture has increased in volume and looks thick. Add in the vanilla extract and vinegar, blending until combined. Now comes the fun part. Add the pink food coloring, just a pea sized amount at a time, until you reach your desired pink hue. Remember that the color will lighten slightly after adding the flour, so aim for a shade slightly darker than your final goal.

Step 3: Mix Dry and Wet Ingredients

Sift half of the cake flour, all of the baking powder, and all of the baking soda directly into the bowl with the batter. Add the buttermilk and use a whisk to gently fold everything together. Sift in the remaining flour and fold well with the whisk. You want to break up most of the lumps to create a mostly smooth batter, but be very careful not to overmix. Overmixing can ruin the tender texture we want for this Birthday Cake Aesthetic.

Step 4: Bake the Layers

Evenly divide the batter between your three greased and lined baking pans. Smooth the tops of the batter and gently tap the pans on the counter to release large air pockets. Bake for 15 to 18 minutes. You will know they are done when a toothpick inserted into the center comes out mostly clean with just a few crumbs attached.

Step 5: Cool and Trim

Remove the cakes from the oven and let the layers cool for 8 minutes inside the pans. Loosen the edges with a spatula and turn them out onto cooling racks to cool completely. Once cooled, use a serrated knife and a gentle sawing motion to trim the edges, top, and bottom of the layers. You only want to trim off the golden brown bits. This reveals the clean, pink interior that defines the modern Birthday Cake Aesthetic.

Step 6: Make the Frosting

In a large bowl or stand mixer, beat the butter with a paddle attachment until it is creamy and lightened in color. Add the salt and powdered sugar, one cup at a time. Beat well between each addition and scrape down the sides of the bowl frequently. Whip until the mixture is very creamy and light. Add pieces of cream cheese, blending well before adding the next piece. The frosting will become very light and fluffy. Finally, add the vanilla and beat again.

Step 7: Assemble the Cake

Smear a small dollop of frosting onto your serving plate or cake stand to secure the cake. Place the first layer down and spread about ⅓ cup of frosting in an even layer on top. Repeat this until the last layer is placed. Cover the stacked cake with a very thin layer of frosting all over the top and sides to create a crumb coat. Use a long metal spatula or cake scraper to help spread it. Pop the cake in the freezer for 10 minutes to set and lock in the crumbs.

Step 8: Decorate with Vintage Piping

While the crumb coat chills, divide your remaining frosting. Transfer about 1 cup of frosting into a medium bowl for white piping. Color the remaining bulk of the frosting a pale pink. Cover the cake with this pale pink frosting and smooth the sides and top. Set aside a third of the remaining pink frosting and add more red and pink coloring to the rest to create a darker pink. You should now have three piping bags: white, pale pink, and dark pink. Use a large open star tip (like a Wilton 1M) for the dark pink, a small open star tip for the pale pink, and a round tip (or just a cut bag) for the white. Pipe borders and swoops all along the edges and sides to achieve that maximalist Birthday Cake Aesthetic.

How To Store Leftovers

If you somehow have leftovers of this delicious cake, storing it correctly is key to maintaining that fresh taste. Because of the cream cheese in the frosting, this cake should be kept in the refrigerator. You can store it in an airtight cake carrier for up to 5 days. If you have already sliced it, press a piece of plastic wrap directly against the exposed cake crumb to prevent it from drying out.

For longer storage, you can freeze individual slices. Wrap each slice tightly in plastic wrap and then place them in a freezer safe bag or container. They will stay good for up to 2 months. When you are ready to eat, just let the slice thaw in the fridge overnight or on the counter for about 30 minutes. This ensures you can enjoy your 18Th Birthday Cake memories long after the party is over.

Tips

Achieving the perfect Birthday Cake Aesthetic requires a few insider tricks. Here is how to ensure success.

First, temperature matters immensely. Make sure your butter, eggs, and buttermilk are truly at room temperature. This creates an emulsion that traps air, resulting in a fluffy cake. If your ingredients are cold, the batter might curdle or bake unevenly.

When it comes to the color, go easy on the gel. It is very potent. You can always add more, but you cannot take it out. For that vintage look, soft pastels are usually better than neon brights. Also, do not skip the trimming step. Removing the browned edges is what makes the slice look professional and clean, which is a huge part of the Birthday Cake Aesthetic.

Finally, if your frosting feels too soft to pipe those intricate swoops, put the piping bag in the fridge for 5 to 10 minutes. The butter in the frosting needs to be cool enough to hold its shape. If it is too warm, your beautiful vintage piping will droop.

Conclusion

Making a cake that fits the trending Birthday Cake Aesthetic is a rewarding project that pays off in both taste and style. Whether you are baking an 18Th Birthday Cake for a milestone celebration or just testing out Birthday Cake Ideas for a fun weekend project, this recipe delivers on all fronts. The combination of moist, tender pink cake and rich, creamy frosting is timeless.

We hope you love making this recipe as much as you will love eating it. There is nothing quite like the satisfaction of slicing into a cake that looks this good and knowing you made it yourself.

FAQ

Can I Make This Gluten Free?

Yes, you can swap the cake flour for a high quality gluten free 1 to 1 baking flour. Just keep in mind that the texture might be slightly denser than with traditional cake flour, but it will still be delicious.

Why Did My Cake Sink in the Middle?

This usually happens if the oven door was opened too early or if the batter was overmixed. Try to keep the oven door closed until the minimum baking time has passed to keep the heat consistent.

Can I Use All Butter Instead of Oil?

While you can, the oil is what keeps this cake moist for days. Using only butter might result in a cake that dries out faster, especially when stored in the fridge.

How Do I Get Super Smooth Sides?

A metal cake scraper and a turntable are your best friends here. Run the scraper around the side while spinning the table. dipping the scraper in hot water and wiping it dry before smoothing can also help melt the butter slightly for a glass like finish.

Notes

Ensure butter, eggs, and buttermilk are at room temperature for a fluffy cake. This helps create a smooth batter.

Use gel food coloring sparingly; it’s very potent. You can always add more, but you can’t take it away.

If your frosting feels too soft for piping, chill the piping bag in the fridge for 5-10 minutes to firm it up.
