Cake Batter Lava Cake

This is the cake I want when I want something completely over the top and all I can think about is the nostalgic taste of cake batter.

The filling thickens as it cools, then loosens into that dramatic lava moment when the first slice is removed. A tall buttercream dam keeps every layer supported until you are ready to cut it.

The Cake Batter Detour I Always Took

I made this cake selfishly because cake batter is undeniably my favorite artificial flavor. In college, I could smell it coming from Cold Stone on my way home. I tried to walk past, but nine times out of ten I found a reason why I deserved a sweet treat.

Now, anytime I smell cake batter, I think of those stops. This cake takes that same nostalgic flavor and turns it into the ultimate celebration cake, with funfetti layers, molten filling, cookie dough pieces, and more sprinkles than strictly necessary.

Ingredient notes

Key ingredients

Cake batter extract

Cake batter extract creates the familiar bakery flavor at the center of this recipe.

Rainbow sprinkles

Rainbow sprinkles run through the cake, cookie dough, and decoration.

Cake flour and cornstarch

This combination keeps the funfetti layers soft and tender while giving them enough structure to support the lava filling.

Vanilla bean paste

Vanilla bean paste rounds out the cake batter extract and gives the cake, filling, cookie dough, and buttercream one consistent vanilla base.

Brands I used for this recipe

These are preferences, not requirements. If you choose the non-dairy route, these are the products I test with. Dairy equivalents can be used at the same listed amounts and temperatures.

Baking dairy-free? See my ingredient guide

LorAnn Cake Batter Flavor

I use LorAnn and have not tested another brand in this recipe. It is highly concentrated, so begin with the listed amounts and add more only after tasting.

Forager Unsweetened Plain Yogurt

For a non-dairy version, I test the cake layers with Forager Unsweetened Plain Yogurt. Plain unsweetened dairy yogurt can be used at the same listed amount and temperature.

Country Crock Plant Butter Sticks

For a non-dairy version, I use Country Crock Plant Butter Sticks. They are dependable in the lava, cookie dough, and buttercream, and they are usually easier to find in conventional grocery stores than at Sprouts or Whole Foods. Dairy butter can be used at the same listed amounts and temperatures.

Country Crock Heavy Plant Cream

If you are replacing dairy heavy cream, I highly recommend Country Crock Heavy Plant Cream. It has no aftertaste, behaves more like dairy cream than any alternative I have used, keeps these lava fillings smooth, and makes the buttercream incredibly fluffy. I usually find it at Kroger or Fry's and wish every grocery store carried it. Dairy heavy cream can be used at the same listed amounts and temperatures.

Tested notes

Grams are the source of truth for this recipe.

The filling must cool completely before you judge its final consistency or assemble the cake.

The cake layers should be chilled before stacking, and the cookie dough needs its full 30-minute chill before it is broken into pieces.

If you want sprinkles in the buttercream, fold them in only after the buttercream is already light and fluffy.

Testing notes

Why this works

Add the sprinkles last

Gently fold the sprinkles into the finished cake batter to reduce color bleeding.

Cool the lava before adjusting it

The filling thickens considerably as it cools. Wait until it reaches room temperature before deciding whether it needs a little milk to reach the consistency you want.

Build a tall buttercream dam

Pipe a complete, sturdy ring around each layer. Keep both the lava and cookie dough pieces below the top of the dam so the next cake layer rests securely on buttercream.

Step by step

How It All Comes Together

Step 1
Bake and chill the funfetti layers
Fold the sprinkles into the finished batter, divide it evenly among the pans, and bake until a tester comes out with a few moist crumbs. Chill the wrapped cake layers before assembly.
Divide the batter evenly among the pans. A few extra sprinkles on top are optional.
Step 2
Prepare the cookie dough pieces
Give the cookie dough its full 30-minute chill, then break it into small pieces. Keep the pieces cold so they stay distinct when added between the cake layers.
Chill the cookie dough, then break it into small pieces for layering and decorating.
Step 3
Build a sturdy buttercream dam
Spread a thin layer of vanilla buttercream over the cold cake, then pipe a tall, continuous dam around the edge. The next layer should rest on buttercream, not on the filling.
Start each filling layer with a thin, even coat of buttercream.
Pipe a tall, continuous dam before adding any lava.
Step 4
Add the lava and cookie dough
Spread the completely cooled cake batter lava inside the dam, stopping below the top edge. Press in the chilled cookie-dough pieces without piling them above the dam, then repeat with the second cake layer.
Spread the cooled lava inside the dam, keeping it below the top edge.
Add cookie dough pieces and sprinkles without overfilling the layer.
Step 5
Crumb coat and finish the cake
Apply a thin crumb coat and chill the stacked cake before adding the final buttercream. Decorate with the reserved lava, cookie dough pieces, buttercream, and sprinkles, then slice to reveal the center.

Tips for the best cake

Chill the cake layers and cookie dough before assembly so every layer stays steady while you build the cake.

Apply a thin crumb coat and chill the stacked cake before adding the final buttercream layer.

Reserve some lava, cookie dough pieces, buttercream, and sprinkles for the top of the cake.

Troubleshooting

If This Happens

The cake batter lava looks too thin

Let it cool completely before changing anything. It thickens considerably at room temperature, so judge the consistency only after it has cooled.

The cake batter lava is too thick

Stir in room-temperature milk a little at a time until the filling becomes glossy and slowly spreadable. Add only what it needs.

The filling is pushing through the buttercream

Use chilled cake layers, pipe a tall and continuous buttercream dam, and keep both the lava and cookie dough pieces below the top edge.

Why is the lava grainy?

A little texture is expected once the lava is completely chilled. If it feels very grainy, the sugar may not have dissolved or may have crystallized, especially if the heat was too high. Some organic sugars have larger crystals that take longer to dissolve. You can try gently warming the filling over low heat, stirring without letting it boil hard. Let it cool again before checking the texture. This may help with undissolved sugar, but it is not a guaranteed fix. If it stays coarse and crystallized, remake the filling rather than keep cooking it. If it smells burnt or tastes bitter, discard it and start over.

Before you slice

Texture and serving notes

The cake is best the day it is assembled, when the filling has its softest lava effect.

Warm an individual slice for about 10 seconds if you want the filling to flow more freely.

Keep it good

Storage

Counter

Keep the assembled cake covered at room temperature for up to 8 hours.

Fridge

Store the cake in the refrigerator for up to 3 days and let slices soften at room temperature before serving.

Freezer

Freeze unassembled cake layers and cookie dough separately for up to 1 month.

Freezer

Freeze assembled slices, then thaw them overnight in the refrigerator.

Recipe FAQ

Questions that come up

How do I keep the Cake Batter Lava Cake from sliding?

Use completely cooled cake layers, room-temperature lava that has thickened, chilled cookie dough, and a tall, continuous buttercream dam. Keep the filling below the top of the dam and chill the crumb-coated cake before the final coat.

Can I make the cake batter lava ahead?

Yes. Make it ahead and refrigerate it in an airtight container. Bring it toward room temperature and stir until smooth before assembly, adding milk only if needed to restore a slowly spreadable consistency.

Can I use vanilla extract instead of vanilla bean paste?

Yes. Vanilla extract can replace the vanilla bean paste at the same listed amount, although I prefer vanilla bean paste for its fuller flavor.

Which sprinkles work best in funfetti cake?

Use rainbow jimmies rather than tiny nonpareils. Fold them in quickly at the very end so the colors stay distinct instead of bleeding through the batter.

Should I weigh the ingredients or use volume measurements?

I strongly recommend weighing the ingredients in grams for the most reliable result. Volume measurements are included for convenience, but the amount in a cup can change depending on how an ingredient is filled, packed, or poured. These recipes are easy to follow, but their ratios are precise, so I cannot guarantee the exact same result when volume measurements are used. I still use teaspoons and tablespoons for small amounts like leaveners, salt, spices, and flavorings because those are the most practical measurements.

Can I make this recipe gluten-free?

I have a separate gluten-free version with its own ingredients and method. Follow that recipe rather than swapping the flour in this one. Gluten-Free Cake Batter Lava Cake

Can I use all-purpose flour instead of cake flour?

Yes, of course. Replace the cake flour with the same amount of all-purpose flour by weight. The cake will have a slightly sturdier, less delicate crumb, but it will still be great.

Pan used

I use Fat Daddio's 8-inch anodized aluminum round cake pans for this recipe.

Instructions

1Make the cake layers. Preheat the oven to 350°F. Grease three 8-inch round cake pans and line the bottoms with parchment paper.
2In a medium bowl, whisk together the cake flour, cornstarch, baking powder, baking soda, and salt until evenly combined.
3In a large bowl, whisk together the granulated sugar, milk, apple cider vinegar, yogurt, neutral oil, vanilla bean paste, and cake batter extract until smooth and emulsified.
4Sift the dry ingredients over the wet ingredients and whisk gently just until combined. Do not overmix.
5Gently fold the sprinkles into the finished cake batter to reduce color bleeding.
6Divide the batter evenly among the prepared pans. If you like, sprinkle a few additional rainbow sprinkles over the batter in each pan before baking.
7Bake for 22-25 minutes, checking at 22 minutes. The centers should spring back and a tester should come out with a few moist crumbs.
8Cool the cakes in the pans for 8-10 minutes, then turn them out onto wire racks. Wrap the layers while slightly warm and refrigerate or freeze until chilled.
9Make the molten filling. Combine the granulated sugar, butter, and cream in a saucepan over medium heat. Whisk until melted and smooth.
10Whisk in the cake flour and salt. Simmer for 2-3 minutes, whisking, until glossy and slightly thickened.
11Remove from the heat and whisk in the vanilla bean paste and cake batter extract. Cool completely to room temperature before assembly.
12Judge the filling only after it has cooled. If needed, stir in room-temperature milk a little at a time until it reaches your desired slowly spreadable consistency.
13Make the cookie dough. Beat the butter and granulated sugar until light and fluffy. Add the vanilla bean paste, cake batter extract, and salt.
14Mix in the all-purpose flour until a dough forms, then fold in the rainbow sprinkles and white chocolate chips. Refrigerate for 30 minutes.
15Make the buttercream. Beat the butter for 2-3 minutes, until smooth and light.
16Add the powdered sugar, vanilla bean paste, cake batter extract, and salt. Mix on low until combined.
17Add the cream gradually and beat until the buttercream is fluffy and spreadable. Fold in the sprinkles at the end if you want a speckled finish.
18Assemble the cake. Place the first chilled cake layer on a cake board. Spread a thin layer of buttercream over the cake, then pipe a tall, continuous buttercream dam around the outer edge.
19Spread some of the room-temperature funfetti filling inside the dam, keeping it below the top edge. Press small chilled cookie dough pieces into the filling.
20Add the second cake layer and repeat with buttercream, a sturdy dam, filling, and cookie dough pieces. Top with the final cake layer.
21Apply a thin crumb coat and refrigerate the cake for 15 minutes.
22Frost the cake with the vanilla sprinkle buttercream. Decorate with the remaining filling, cookie dough pieces, buttercream, and sprinkles.

The cake turned out amazing!!🤩 it was my first time EVER making a layered cake and at that, one that had molten lava. All the steps were so easy to follow and I loved how there is a “what if this happens” section that I could refer whenever I had a question or thought things were going south 🤣 … but it turned out tasty and perfect for a classic cake batter & sprinkle flavor I was looking for!!
