Ingredients

For The Vanilla Cake

3 cups all-purpose flour
2 ½ teaspoons baking powder
½ teaspoon baking soda
½ teaspoon salt
1 cup unsalted butter, softened
2 cups granulated sugar
4 large eggs
1 tablespoon vanilla extract
1 cup whole milk
½ cup plain yogurt

For The Vanilla Buttercream Frosting

1 ½ cups unsalted butter, softened
5 cups powdered sugar, sifted
2 teaspoons vanilla extract
3-4 tablespoons whole milk (adjust for consistency)
A pinch of salt

For Decorating The Cat Face

Black fondant (for eyes, lashes, whiskers, nose outline, and mouth)
White fondant (for the nose and inside of the ears)
Green fondant (for the irises)
Light blue fondant (optional, for a slight eye highlight)
Red fondant (for the striped inner part of the ears)
Edible glue or water (for sticking fondant pieces)
Small round piping tip and piping bag (for buttercream borders and ear edges)

Instructions

Preheat the oven to 350°F (175°C) and grease and line two 8-inch round cake pans with parchment paper.
In a bowl, whisk together the flour, baking powder, baking soda, and salt; set aside.
In a large mixing bowl, beat the softened butter and sugar until light and fluffy, about 3-4 minutes.
Add eggs one at a time, mixing well after each addition, then stir in the vanilla extract.
Mix in the flour mixture in three parts, alternating with the milk and yogurt, beginning and ending with the dry ingredients. Do not overmix.
Divide the batter evenly between the prepared pans and bake for 30-35 minutes or until a toothpick inserted into the center comes out clean.
Let the cakes cool in the pans for 10 minutes, then transfer them to wire racks to cool completely.
To make the buttercream, beat the softened butter until creamy.
Gradually add sifted powdered sugar, mixing well.
Stir in the vanilla extract and a pinch of salt.
Add milk one tablespoon at a time until the frosting is smooth and spreadable.
Once cakes are completely cool, level them using a serrated knife.
Stack the two layers with buttercream in between and apply a crumb coat (thin layer of buttercream) all over the cake.
Chill the cake for 30 minutes, then apply a final smooth layer of buttercream, using an offset spatula.
Roll out the black fondant and cut out two large circles for the outer eyes, 6 thin strips for the whiskers, 2 eyelash shapes, and the outline for the nose and mouth.
Roll out the green fondant and cut out two smaller circles for the irises.
Roll out a tiny amount of light blue fondant (optional) for a highlight dot on the eyes.
Roll out the white fondant and shape an oval for the nose and the triangular inner parts of the ears.
Roll out the red fondant and cut out two triangles slightly smaller than the white ones; stripe them using thin strips of white fondant to create the red-and-white pattern.
Position the white triangles on top of the cake as ears, sticking them upright with extra buttercream or toothpicks for support.
Add the red-and-white striped triangles on top of the white ones and pipe small buttercream dots around the edge of each ear for detail.
Place the black fondant circles as eyes on the front of the cake.
Layer the green fondant irises inside the black circles and optionally add light blue fondant dots.
Add the black fondant eyelashes to the outer corners of the eyes.
Position the white fondant oval as the cat’s muzzle at the center base of the cake.
Attach the black fondant nose and pipe or stick on the black mouth underneath.
Arrange the whiskers coming out from both sides of the muzzle.
Pipe a shell or rope border around the base of the cake using a small round piping tip and the remaining buttercream.
Chill the finished cake for 15-20 minutes to set everything in place before serving.

What Basic Tools Do I Need To Decorate A Cat-Shaped Cake?

You don’t need anything fancy to make this cake come to life. A few simple tools will help you build and decorate it smoothly:

Offset spatula: to spread and smooth the buttercream.
Piping bags and star tip: for piping the rope border and small buttercream details.
Fondant rolling pin: helps roll out fondant evenly.
Fondant cutter or sharp knife: for cutting out fondant shapes.
Small round cutters or bottle caps: to shape the eyes and nose.
Cake board or cake stand: to display the finished cake.
Toothpicks or skewers: to secure the ears on top.

How Do I Get Smooth Buttercream Frosting Like In Professional Cakes?

A smooth buttercream finish gives your cake a clean and polished look, just like bakery cakes. It’s not as hard as it looks if you follow these tips:

Start with chilled cake layers: cold cake layers reduce crumbs.
Apply a thin crumb coat first: this traps loose crumbs and sets the base.
Chill the crumb-coated cake: about 20-30 minutes in the fridge helps the base firm up.
Use an offset spatula or bench scraper: gently smooth the buttercream by spinning the cake on a turntable.
Use warm water: dip your spatula in hot water, wipe it dry, and smooth over the buttercream for a sleek finish.
Don’t rush: working slowly gives you better control over the final look.

Can I Make This Cat Birthday Cake Ahead Of Time?

Yes, making this cake ahead of time is a smart move, especially if you’re planning for a party. It helps you avoid last-minute stress and gives time for the decorations to set properly.

Here’s how you can do it:

Bake the cake layers 1 to 2 days in advance. Wrap them tightly in plastic wrap and store them in the fridge.
Prepare the buttercream and fondant decorations a day before assembling the cake.
Assemble and decorate the entire cake the night before the event, then keep it in the fridge.
Bring it to room temperature for about 1 hour before serving so the cake is soft and easy to slice.

How Do I Keep The Fondant Decorations From Drying Out Or Cracking?

Fondant can dry out quickly if not handled properly, but there are simple ways to keep it soft and smooth while you work.

Cover unused fondant: always keep it wrapped in plastic wrap or inside an airtight container.
Work on a non-stick surface: use a silicone mat or dust your work surface lightly with cornstarch.
Knead the fondant well: softens it and prevents cracking.
Avoid working under fans or in very dry rooms: air circulation makes fondant dry too fast.
Lightly brush decorations with a bit of shortening if they look dry.

If you make fondant decorations like the cat’s ears and face pieces in advance, store them in a sealed box at room temperature (avoid the fridge to prevent sweating when they warm up).

What Type Of Fondant Is Best For Details Like Eyes And Whiskers?

For small decorations like the cat’s eyes, whiskers, nose, and mouth, you’ll want fondant that holds its shape well but is still easy to roll out.

Use rolled fondant for most parts: it’s soft, easy to handle, and works well for flat decorations.
For very fine or thin details like whiskers, you can use gum paste or mix a little Tylose powder into regular fondant to make it firmer.
Black fondant is usually recommended for eyes, lashes, and whiskers because it gives a bold, clean finish.
Pre-colored fondant saves time and gives you rich colors without the hassle of mixing food coloring.

How Do I Store The Decorated Cake Before Serving?

To keep your cat cake fresh and looking great before the party, it’s important to store it the right way. You don’t want your decorations to wilt or your cake to dry out.

Place the decorated cake in the fridge as soon as it’s done.
Put it inside a cake box or cover it with a large dome to protect it from dust and odors.
Keep the cake away from strong-smelling foods like onions or garlic, so it doesn’t pick up strange tastes.
Take it out of the fridge about 1 hour before serving, so the cake softens to the perfect texture.

What’s The Easiest Way To Transport Cat Birthday Cake To A Party?

Transporting a tall, detailed cake like this cat design might sound tricky, but here’s how to make it easy and safe.

Chill the cake first so the buttercream and fondant harden slightly.
Use a sturdy cake board that is at least 2 inches larger than the cake itself.
Place the cake in a tall cake box for protection.
In the car, put the cake on a flat surface like the trunk or the car floor, not the seats.
Drive slowly and avoid sharp turns or sudden stops.

How Long Does It Take To Decorate The Cake Once Baked?

Decorating this cake takes some patience, but the end result is worth it. Here’s a simple breakdown to help you plan your time.

Crumb-coating and applying the final layer of buttercream will take about 30 to 40 minutes.
Chilling the cake in between steps adds another 30 minutes.
Making and shaping all the fondant decorations, like the eyes, nose, whiskers, and ears, will take around 45 to 60 minutes.
Adding the decorations and final touches takes about 20 minutes.

In total, decorating the cake should take around 2 to 3 hours depending on your speed and skill.

What Should I Do If My Buttercream Starts Melting While Decorating?

Warm kitchens or long decorating times can cause buttercream to melt. Here’s what to do if that happens:

Stop decorating and place the cake in the fridge for about 20 to 30 minutes to firm it back up.
If possible, move to a cooler room or turn on a fan to lower the temperature.
Dip your spatula in ice water, dry it, and use it to smooth out soft spots.
Try not to touch the cake too much, as your hands can warm the buttercream even more.
Make sure your buttercream is thick enough before applying more.
