The Perfect Molly Cake Recipe (Soft, Moist & Sturdy)

Welcome to the ultimate secret weapon of cake decorators! If you have ever struggled with finding a sponge cake that is tall, sturdy enough to hold heavy fillings, yet incredibly soft and moist, you need to meet the Molly Cake. It is the absolute star of the cake design world. Whether you are building a simple birthday cake or a towering wedding centerpiece, this foolproof, no-butter sponge cake will completely change the way you bake.

What is it

Invented by the talented Italian cake designer Eleonora “Molly” Coppini, the Molly Cake is a revolutionary sponge cake variation. Unlike a classic White Cake that relies on creaming butter and sugar, the Molly Cake uses zero butter and zero oil. Instead, the fat and moisture come entirely from heavy whipping cream that has been whipped to soft peaks and folded into the batter. This unique method creates an exceptionally light, airy, yet structurally firm crumb. It is also known for baking beautifully flat, meaning you won’t have to trim off large, wasteful domes from your cake layers!

Why you’ll love it

• Perfect for Carving: Because of its sturdy texture, it holds sharp edges beautifully and won’t crumble when you carve it for custom cake designs.
• No Soaking Required: The whipped cream keeps the crumb intensely moist, so you do not need to drench it in simple syrup before assembling.
• Flat Baking: It rises evenly in the oven, giving you perfectly level layers right out of the pan.
• Versatile Flavor: It is a wonderful blank canvas. You can pair it with anything from fresh fruit to a rich Swiss Meringue Buttercream.

Ingredients

The traditional Molly Cake is famous for its simple, equal-parts ratio. For two 6-inch (15cm) round cake pans, you will need:

• 3 Large Eggs (approx. 150g): Must be strictly at room temperature to whip properly.
• 150g Granulated Sugar: Extra-fine sugar works best so it dissolves easily into the eggs.
• 150g Cake Flour: Sifted, to ensure the softest crumb possible.
• 150g Heavy Whipping Cream (at least 30% fat): This must be very cold so it whips up into a thick cream.
• 7g Baking Powder: To help the cake rise tall.
• 1 tsp Pure Vanilla Extract & a pinch of salt: To enhance the overall flavor.

How to make

Follow these steps carefully to ensure your cake turns out fluffy, not dense:

1. Whip the Eggs: In a stand mixer, whisk the room-temperature eggs, sugar, and vanilla extract on high speed for about 10-15 minutes. The mixture must double or triple in volume and turn very pale and fluffy.
2. Whip the Cream: In a separate chilled bowl, whip your cold heavy cream until it reaches firm (but not stiff or grainy) peaks. If you have ever made our Stabilized Whipped Cream, you know you want it thick but still smooth. Set it aside in the fridge.
3. Add Dry Ingredients: Sift the cake flour, baking powder, and salt together. Turn your mixer to the lowest speed and gently mix the dry ingredients into the egg mixture. Only mix for about 1 minute until just combined.
4. Fold in the Cream: Take your whipped cream and gently fold it into the batter using a rubber spatula. Use a light, sweeping motion from the bottom to the top so you don’t deflate the airy batter.
5. Bake: Divide the batter evenly between two parchment-lined 6-inch pans. Bake at 320°F (160°C) for 50-60 minutes. Do not open the oven door during the first 40 minutes! Test with a toothpick before removing.

How To Serve

Because it holds its shape so well, this cake is perfect for tall, modern layer cakes. You can slice the layers, fill them with fresh strawberries and vanilla cream to make a stunning Strawberry Vanilla Cake, or coat the outside in a sleek layer of ganache before covering it in fondant.

How To Store

• Room Temperature: Wrap the cooled cake tightly in plastic wrap. It will stay fresh and moist at room temperature for up to 3-4 days.
• Refrigerator: Wrapped well, it lasts up to 1 week.
• Freezer: This cake freezes exceptionally well! Wrap the layers in plastic wrap, then aluminum foil, and freeze for up to 3 months. Let them thaw slowly in the fridge overnight before decorating.

FAQs

Can I make a chocolate version?
Yes! To make a chocolate Molly Cake, simply replace about 15-20% of the flour weight with high-quality, unsweetened cocoa powder.
Why didn’t my cake rise?
This usually happens if you did not whip the eggs and sugar long enough (it really needs that full 10-15 minutes to incorporate air), or if you folded the whipped cream too aggressively and knocked the air out of the batter.
Can I use a larger pan?
Absolutely. The beauty of this recipe is the equal-parts ratio. If you need an 8-inch cake, simply scale up the ingredients (e.g., 250g eggs, 250g sugar, 250g flour, 250g heavy cream).

Note

Do not use light cream or half-and-half for this recipe. The heavy whipping cream needs a high fat content (at least 30-35%) to whip properly and provide the necessary fat structure that replaces the butter.

Nutrition information

A standard 6-inch Molly Cake yields about 8-10 servings. Because it contains heavy cream, one unfrosted slice has approximately 240-260 calories. The high fat content from the cream is what gives this cake its signature melt-in-the-mouth texture.

Tips and Tricks

For the easiest release, do not just grease your pans—always line the bottom and the sides with parchment paper. Also, once you remove the cakes from the oven, let them cool in the pan for 10 minutes, then turn them upside down onto a wire cooling rack. Cooling them upside down guarantees a perfectly flat top for your layer cakes!
