The secret is not fancy equipment. It is a level cake, a smooth crumb coat, and buttercream that is soft enough to swirl but firm enough to hold its shape. I will walk you through every step, including the exact temperatures and times.
Whether you are baking for a birthday, a baby shower, or just because, this cake gives you that polished bakery look at home. Let's make something worth photographing.
Why You'll Love This Recipe
About the Ingredients
2 3/4 cups (330g) all-purpose flour
Spoon flour into the cup and level it off so you do not pack it down. If you are out of all-purpose, cake flour works too; use 3 cups (330g) and the crumb gets even softer.
2 1/2 teaspoons baking powder
Check the date on your can, because old baking powder is the number one reason cakes turn out flat. Buy a fresh can before a big bake.
3/4 teaspoon fine sea salt
Fine sea salt dissolves evenly into the batter. If you only have table salt, use a scant 3/4 teaspoon.
1 1/2 cups (300g) granulated sugar
Standard white sugar gives the cleanest vanilla flavor. Caster sugar works as a one-to-one swap and dissolves a touch faster.
3/4 cup (170g) unsalted butter, softened
Let it sit at room temperature for about an hour so it creams smoothly. Salted butter works if you drop the added salt to 1/4 teaspoon.
4 large eggs, room temperature
Room-temperature eggs emulsify better and keep the batter from curdling. Quick trick: place them in warm water for 10 minutes.
1 tablespoon vanilla extract
Real vanilla extract gives the best flavor. Vanilla bean paste is a lovely swap and adds those pretty little flecks.
1 cup (240ml) buttermilk, room temperature
No buttermilk? Stir 1 tablespoon lemon juice into 1 cup whole milk and rest it for 10 minutes.
1 1/2 cups (340g) unsalted butter, softened, for the buttercream
Use butter that dents when you press it but is not greasy. European-style butter holds up especially well in warm kitchens.
5 cups (600g) powdered sugar, sifted
Sifting keeps the buttercream lump-free. If your sugar is clumpy, pulse it in a food processor instead.
2 teaspoons vanilla extract, for the buttercream
Add this last so you can taste and adjust. Clear vanilla keeps the buttercream bright white for pastel coloring.
Gel food coloring in 3 pastel shades
Gel colors are far more concentrated than liquid drops and will not water down your frosting. Start with a tiny dot on a toothpick.
Tips & Tricks
Measure Flour Gently
Scooping straight from the bag packs the cup and makes a dry cake, so always spoon and level. I keep a small bowl next to my flour can just for this.
Get Room-Temperature Butter
Cold butter makes lumpy buttercream that never smooths out. Press your thumb into the stick; if it leaves a gentle dent, you are ready.
Chill Before the Final Coat
A 20-minute chill after the crumb coat stops crumbs from showing up in your pretty top layer. Set a timer so you do not forget.
Pro Tips
Step-by-Step Instructions
1. Heat the oven and prep pans
Preheat your oven to 350°F (175°C). Grease two 8-inch round pans, line the bottoms with parchment, and grease the paper again.
2. Cream butter and sugar
Beat the softened butter and sugar on medium-high for 3 to 4 minutes until pale and fluffy. You will see the mixture lighten in color and grow in volume.
3. Add eggs one at a time
Beat in the eggs one at a time, then the vanilla, scraping the bowl between additions. The batter should look glossy and smooth, not curdled.
4. Alternate dry and wet
Mix the flour, baking powder, and salt in a bowl. Add it in three additions, alternating with the buttermilk, starting and ending with the dry ingredients. Stop mixing the moment the last streak of flour disappears.
5. Bake until golden
Divide the batter between the pans and bake at 350°F (175°C) for 28 to 32 minutes, until the tops are golden and a toothpick comes out with just a few moist crumbs. The center should read 205°F (96°C) on a thermometer.
6. Cool completely
Let the cakes rest in the pans for 10 minutes, then turn them out onto a rack. Cool fully for at least 45 minutes before frosting, or the buttercream will melt.
7. Whip the buttercream
Beat the softened butter for 3 minutes, then add the sifted powdered sugar one cup at a time. Add the vanilla and beat 5 minutes until fluffy and smooth.
8. Crumb coat and chill
Spread a thin layer of plain buttercream over the stacked cake and chill for 20 minutes. This traps loose crumbs so your final coat stays clean.
9. Swirl and decorate
Tint the remaining buttercream in pastel shades, then pipe swirls over the chilled cake with a star tip. Work from the bottom up and keep the pressure steady for even rosettes.
Delicious Variations
Chocolate Lover's Version
Swap 1/2 cup of the flour for cocoa powder and add 1/4 cup extra buttermilk for a rich chocolate crumb.
Lemon Berry Twist
Add 1 tablespoon lemon zest to the batter and fold fresh raspberries between the layers for a bright summer cake.
Cupcake Style
Divide the batter into 24 cupcake liners and bake at 350°F (175°C) for 18 to 20 minutes for easy single-serve treats.
How to Store Pinterest Image Cake
Refrigerator
Store the frosted cake in an airtight container in the fridge for up to 4 days. Let it sit out for 30 minutes before serving so the buttercream softens.
Freezer
Wrap unfrosted cake layers tightly in plastic and foil, then freeze for up to 2 months. Thaw overnight in the fridge before decorating.
Reheating
No reheating needed. Bring chilled slices to room temperature for 20 to 30 minutes, or microwave a single slice for 10 seconds to soften the crumb.
Frequently Asked Questions
Q: Can I make this cake ahead of time?
Yes, you can bake the layers up to 2 days ahead and keep them wrapped at room temperature. Frosting the cake the day you serve it gives the freshest look and flavor.
Q: Why did my buttercream turn out grainy?
Grainy buttercream usually means the butter was too cold or the sugar was not sifted. Let the butter soften fully and sift the powdered sugar, then beat for a full 5 minutes to smooth it out.
Q: How do I get pastel colors without them turning muddy?
Use gel food coloring and add it a tiny dot at a time. Liquid coloring adds water and dulls the shade, while gel keeps colors clean and bright.
Q: Can I use a 9-inch pan instead of 8-inch?
Yes, but your layers will be thinner and bake faster. Start checking at 22 minutes and rely on the toothpick test rather than the clock.
Q: How do I keep the cake from doming?
Bake at the temperature listed and avoid overmixing, which can cause doming. You can also wrap damp baking strips around the pans for perfectly level tops.
