Vanilla Bean Cake with Vanilla Buttercream

Jump to Recipe Print Recipe

(soft, classic, and always worth making)

Some recipes don’t need to be complicated to be good.

This vanilla bean cake is one of those. It’s soft, light, and full of real vanilla flavor with a tender crumb that stays moist without feeling heavy. Paired with a simple vanilla buttercream, it’s the kind of cake that works for just about anything.

Birthdays, baby showers, holidays, or even just a weekend when you feel like baking something simple and good.

It’s also one of the most versatile recipes I make. The same base cake can look completely different depending on how you decorate it, and I’ve used it for everything from simple layered cakes to more styled, bakery-inspired designs.

Why This Vanilla Cake Works

There are a lot of vanilla cake recipes out there, and not all of them deliver.

This one is:

  • soft and fluffy, but still sturdy enough to layer
  • full of real vanilla flavor (not flat or bland)
  • easy to work with for decorating
  • reliable, even if you’re newer to baking

It’s the kind of recipe you can come back to again and again.

Vanilla Buttercream Frosting

The frosting is simple, but it’s what brings everything together.

It’s smooth, creamy, and just sweet enough without being overwhelming. It spreads easily and pipes beautifully, which makes it perfect whether you’re going for a clean finish or something more textured.

Classic Vanilla Buttercream Frosting

This is a basic vanilla buttercream frosting that pairs perfectly with confetti cake. It pipes well, spreads easily, and tastes like traditional birthday cake frosting.

Ingredients

  • 1 cup unsalted butter softened
  • 3 1/2 – 4 cups powdered sugar
  • 2-3 tbsp milk or cream
  • 2 tsp vanilla extract
  • pinch of salt

Instructions

  • Beat butter for 2–3 minutes until smooth and pale.
  • Add powdered sugar gradually, mixing between additions.
  • Add vanilla, salt, and 2 tbsp milk.
  • Beat on medium-high for 2–3 minutes until fluffy.

Notes

Adjust texture:
too thick = add milk 1 tsp at a time
too soft = add powdered sugar
If you want a bakery-style finish, beat it longer than you think you need — extra air makes a big difference.

How to Assemble

  1. Level cakes if needed
  2. Place first layer on cake stand
  3. Add frosting and spread evenly
  4. Add second layer
  5. Frost top and sides

Optional:

  • keep it smooth
  • do a light “naked” finish
  • add piping on top
  • or add fresh fruit

Tips for Best Results

Use room temp ingredients
This helps everything mix smoothly.

Don’t overmix the batter
Overmixing = dense cake.

Use vanilla bean paste if you can
It gives better flavor and those little specks.

Measure flour correctly
Spoon and level — don’t scoop.
