So, whether it’s for a birthday, a comeback party, or just a Tuesday when you feel like celebrating the diamond life, this is your official guide. Let’s get ready to bake, Carats. This is the perfect Going Seventeen cake tutorial.

Why This Recipe Is Ready to Love

In a world full of themed cakes, why is this specific Going Seventeen cake the one you absolutely have to make?

First, it’s a stunning tribute to the fandom. We’re using SEVENTEEN’s official colors, Rose Quartz and Serenity, to create a beautiful watercolor frosting effect. Any Carat will instantly recognize the color palette, and anyone else will just see a gorgeous, dreamy cake. It’s an “if you know, you know” masterpiece.

Second, the flavor is as fresh as a debut. To match the bright, vibrant energy of the group, we’re making a light and zesty Lemon Blueberry cake. It’s a sophisticated, delicious flavor that’s a step above your average party cake and feels perfectly on-brand.

Finally, it looks “Oh My!” levels of impressive, but it’s easier than the “Fear” choreography. Seriously. The watercolor frosting technique is one of the best-kept secrets in baking because it looks incredibly professional but is very beginner-friendly. You don’t need to be a master decorator to create this Going Seventeen cake.

The Performance: Step-by-Step Instructions

Ready to rock with this cake? Let’s break down the choreography for the perfect Going Seventeen cake.

Part 1: The Pre-Debut (The Cake)

Step 1: Get Ready Preheat your oven to 350°F (175°C). Grease and flour your cake pans. In a medium bowl, whisk together the flour, baking powder, and salt.

Step 2: The Main Vocal In your stand mixer, beat the butter and sugar for 5 minutes until very light and fluffy. Rub the lemon zest into the sugar first for extra flavor! Beat in the eggs one at a time.

Step 3: The Chorus In a separate container, stir together the buttermilk and lemon juice. On low speed, alternate adding the dry ingredients and the buttermilk mixture, starting and ending with the dry. In a small bowl, toss your blueberries with a tablespoon of flour (this stops them from sinking!). Gently fold the floured blueberries into the finished batter.

Step 4: The Debut Stage Divide the batter between your pans and bake for 30-35 minutes. Let the cakes cool completely on a wire rack.

Part 2: The Comeback Stage (The Buttercream)

Step 5: The Meringue In the clean bowl of your stand mixer, whisk the egg whites and sugar. Place the bowl over a saucepan of simmering water and whisk constantly until the mixture reaches 160°F (71°C) on a candy thermometer.

Step 6: The Whip Transfer the bowl to your mixer and whisk on high speed for 10-15 minutes, until the meringue is stiff, glossy, and the outside of the bowl is completely cool.

Step 7: The Final Unit Switch to the paddle attachment. On low speed, add the cool, cubed butter a few pieces at a time. It will look curdled—keep mixing! It will come together into a silky buttercream. Mix in the vanilla and salt. Divide the buttercream into three bowls. Leave one white, tint one a soft Rose Quartz pink, and tint the other a dreamy Serenity blue.

Part 3: The Grand Finale (The Assembly)

Step 8: The Base Coat Level and stack your cooled cake layers with a thin layer of white buttercream. Apply a thin crumb coat and chill for 30 minutes. Apply a final, perfectly smooth coat of white buttercream using your bench scraper. This pristine canvas is the key to a beautiful Going Seventeen cake.

Step 9: The Watercolor Effect Randomly dot splotches of your Rose Quartz and Serenity buttercream onto your chilled white cake. Now for the magic: take your clean bench scraper, hold it against the side, and do one or two smooth, continuous passes using your turntable. The colors will blend into a beautiful, dreamy watercolor finish.

Step 10: The Diamond Edge Finish your masterpiece with a delicate scattering of white sugar pearls and a generous dusting of edible glitter. Your perfect Going Seventeen cake is now ready for its close-up.

Nutritional Info (Carat-Approved)

A report from the performance team.

• Serving Size: One “Aju Nice!” slice.
• Energy Level: Enough to get you through a 3-hour concert encore.
• Calories: We don’t count calories in the diamond life. We count memories. (But for the record, it’s about 650 per slice. Worth it for this Going seventeen cake.)
• Primary Benefit: Will make your heart go “BOOMBOOM.”

Common Mistakes to Avoid (Don’t Be a Pabo)

Let’s avoid these common slip-ups.

• The “Fallin’ Flower” Frosting: Your Swiss meringue is a soupy, broken mess. You likely added the butter when the meringue was still warm. The meringue must be completely cool. If it breaks, just keep mixing on low; it will almost always come back together.
• The Muddy Middle: You over-blended your Rose Quartz and Serenity frostings, and now your cake is a sad, murky gray-purple. Do one or two smooth passes with the bench scraper and then STOP. The beauty is in the gentle blend, not a complete mix.
• The Sinking Ship Blueberries: All your blueberries sank to the bottom of the cake. You forgot to toss them in a little flour before folding them into the batter. This simple trick helps them stay suspended.
• The Fear of Imperfection: You stressed about making the watercolor pattern perfect. It’s an abstract design! It’s supposed to look different and unique every time. That’s the beauty of this Going seventeen cake.

Variations & Customizations

Want to customize your Going Seventeen cake for your favorite era?

1. The “HOT” & Spicy: For a more intense vibe, make a rich dark chocolate cake with a hint of cinnamon and cayenne pepper. Decorate it with a dramatic black and fiery red buttercream.
2. The Carat Bong: Frost a round cake smoothly with white buttercream. Use pink and blue frosting to pipe the diamond shape from the top of the official light stick (the “Carat Bong”) on top of the cake.
3. The BSS (BooSeokSoon) Party: Go for maximum energy! Make a batch of cupcakes and frost them in the subunit’s signature bright orange, blue, and pink colors. Top with fun, flashy sprinkles.
