Why you’ll love this recipe

Vanilla sponge cake made extra tender with a secret ingredient! (ok not so secret, just scroll down).
Frosting is made with just two main ingredients!
Dulce de leche is prominent but doesn’t make the cake overly sweet.

A few months ago I made a chocotorta with a cream cheese dulce de leche filling and I knew I needed to use that glorious cream in another recipe so here we are. The cream cheese perfectly cuts the sweetness of the dulce de leche and it’s SO easy to make.

What is dulce de leche?

Dulce de leche is caramelized sweetened condensed milk. You can either make it yourself by caramelizing it slowly on the stove or in the oven or you can buy it pre-made. The flavor is very similar to caramel sauce but has a much thicker and creamier consistency, like peanut butter.

If you can’t find dulce de leche at the store, I recommend making your own from sweetened condensed milk. I don’t recommend using caramel sauce as a replacement because the consistency is too soft and the frosting will be too soft.

What type of sponge cake is this?

This type of sponge is called a molly cake and it’s known for having whipped cream folded into the batter.

You remember in my book, Frosted, how I introduce you to the type of buttercreams in the beginning of the book and then use those buttercreams in different ways throughout the book?

Well there is a list of base sponge cake recipes, just like that. Of course, everyone makes them a little different but each type of sponge has specific characteristics.

Molly cake is light and fluffy just like most types of sponge cakes. The whipped egg whites and the whipped cream are what make it super fluffy but the addition of egg yolks are what keep it moist and give it flavor. I find that it has a finer crumb and is a little less spongy than other types of sponge cakes.

Ingredients & Substitutions

Flour: I use all purpose flour in most of my recipes and I HIGHLY recommend using a digital scale, as flour is so often over measured. Cake flour also works well in this recipe.
Baking Powder: Most sponge cakes are known for not using a leavening agent since they rely on the eggs to lift the cake. HOWEVER, for this cake I recommend 2 tsp of baking powder because of the higher fat content.
Heavy Cream: I recommend a heavy whipping cream that’s 36-40% fat. Whip it just until you reach stiff peaks, no more, then fold it into the batter.
Sugar: I use granulated sugar. I have not tested it with any other type of sugar but I don’t recommend reducing the sugar in the cake as it’s not super sweet anyway.
Eggs: Make sure to use room temperature, large eggs, about 55-60g each (without the shell).
- Place them in hot water for a few minutes if they’re cold.
- Unfortunately I have not made this cake without eggs but I know some people have had success with using aquafaba for sponge cakes so try looking up a vegan sponge cake recipe if that’s what you’re looking for.
Vanilla: I usually just use a simple vanilla extract in cake batters but I like to use vanilla bean paste for buttercreams and frostings.
Cream Cheese: I always recommend Philadelphia full-fat cream cheese.
Dulce de Leche: I recommend a store bought one like Nestle or Eagle Brand.

Step-by-Step Instructions

Step 1: Start by separating the egg yolks from the whites. Beat the egg whites with the sugar until it’s super thick and fluffy and holds stiff peaks.

Step 2: Add the egg yolks and vanilla and beat at medium-high speed until it’s combined, just a few seconds.

Step 3: Sift in the flour and salt and beat at medium-low speed, just until the flour is mixed in. Use a rubber spatula to fold the mixture a couple of times to scrape the edge of the bowl.

Step 4: Whip the cream in a separate bowl, just until it reaches stiff peaks.

Step 5: Fold the cream into the batter just until it’s completely blended in.

Step 6: Distribute the batter evenly among the pans lined with parchment paper, about 15-16 ounces each, and bake for 25-ish minutes. The tops will be golden brown, no longer wet and spring back when you press on them gently.

Step 7: Beat together the cream cheese with the dulce de leche, vanilla and salt, until it’s smooth and creamy. If the frosting is to soft, refrigerate it for 20-30 minutes, stirring every 5-10 minutes.

Step 8: Once the cakes have cooled, spread a layer of frosting on the first cake and stack the second cake. If the cake/frosting feels too soft, refrigerate is for 15-30 minutes.

How To Frost/Decorate this Dulce de Leche Cake

I kept it simple and just lightly frosted the outside of the cake with the dulce de leche frosting. I made swirls on top with a small offset spatula but if you want, you certainly can decorate the cake too.

If you want to decorate the cake, it may be a little difficult to do it with this cream because it’s so soft. You can lightly frost it like I did, after refrigerating (or freezing) it for a little if necessary, until it’s more sturdy.

If you want to actually frost it nice and decorate the outside of this cake you’ll have to pipe a border of buttercream around the edge of the first layer of cake and then use the dulce de leche frosting as the filling. You can see how I did that for my cranberry orange cake.

I recommend a Swiss Meringue buttercream for decorating but American buttercream also works fine.

Make sure to check out my cookbook Frosted for a million frosting options and how to use them! I also have an ebook, Frosted 2.0, that shows step-by-step photos of all the types of frostings in the cookbook. You can download that below.

Frequently Asked Questions

Can I make this dairy free?

Considering you’ll need dairy free cream, cream cheese and dulce de leche I would say that’s probably not the best idea. Texture wise cakes turn out fine dairy free but with the frosting, it would probably have a totally different flavor.

Can I make this gluten-free?

All my cake recipes work well with a 1:1 gluten-free flour like Bob’s Red Mill and King Arthur Flour HOWEVER, I have not tested this with sponge cakes so I am not entirely sure. Please let us know if you do try it!
UPDATE: someone did test it with gluten-free flour and it worked well!

Can I make this into cupcakes?

Unfortunately sponge cakes don’t bake up as well as cupcakes but I have not tried it with this recipe.

How to know when sponge cakes are done baking

Sponge cakes are fairly easy to assess when they’re done baking. The top will no longer look wet and it’ll have a golden brown color. Then gently press your finger into it and it should have some resistance and/or spring back. If it feels wet underneath the surface, leave it a few more minutes.
Try not to open the oven until it’s close to being done though.

What pan to bake this cake in:

Half batch – one layer 8 inch cake; bake for about 18-20 minutes.
Half batch – one layer 9 inch cake; bake for about 16-19 minutes.
Full batch – three or four layer 6 inch cake; about 7-8 oz each and bake for about 14-16 minutes.
Full batch – two layer 8 inch cake; about 10-11 oz each and bake for about 18-20 minutes.
Full batch – two layer 9 inch cake; about 10-11 oz each and bake for about 16-19 minutes.
Full batch – one layer 9×13 inch cake; bake for about 30-40 minutes.

How to make ahead

To make the cake ahead of time you can make the cakes even a couple weeks in advance. When you remove them from the oven, let them cool for about half an hour and then wrap them individually in plastic wrap. Then place them in a freezer bag, squeezing out all the excess air.

Make sure to work quickly if you frost them while they’re frozen, because the frosting can set way too quickly from the cold cake and make it difficult to spread. Or just pull them out of the freezer 1 hour before frosting.

I recommend baking the dulce de leche frosting fresh.

How to store finished cake

Any cake frosted with cream cheese frosting has to be stored in the refrigerator. I recommend up to 3-4 days in the fridge before it dries out.

To freeze, refrigerate until the frosting is firm, then wrap in plastic wrap and then again in foil. Freeze for a few weeks and thaw in the fridge overnight before serving.

To freeze slices, wrap them individually in plastic wrap. Then place them in a freezer bag, squeezing out all the excess air or place them in an airtight container, followed by the freezer bag.
