Ingredients Needed

For the Cake

• Sour cream: Adding sour cream to baked goods helps with moisture and richness. The acidity will also react well to the baking soda giving it a bit of a rise (but not much of one in the case of this cake!
• Baking soda: A leavening agent that will help to give it about as much rise as going from a crepe to a pancake.
• Eggs: Needed for binding so that the sturdy cake layers hold their shape without crumbling.
• Melted butter: Adding melted butter will help spread out your cake and make it denser than usual. Sort of the way it spreads out cookies when they bake.
• Sugar: The sweet flavor in the cake comes from regular granulated sugar. It’s perfect!
• Vanilla extract: I use the pure extract for that beautiful aromatic vanilla flavor that this cake has.
• Flour: The structure of the cake rounds is all thanks to the flour used. It’s important to measure it properly and adjust it as needed. If you need more, you can add more.

For the Custard Cake Filling

• Sugar: A vanilla custard should always be perfectly sweet!
• Flour: This is used to thicken up the custard so that it is not too thin and runny but has a nice thick consistency to it.
• Eggs: A signature ingredient used for all kinds of custards. It’s what makes it rich and moist and deliciously smooth.
• Milk: I use raw whole milk because that’s what my mom used to do, but you use whatever milk you have on hand. The higher the fat content the richer it will be!
• Butter, cubed: Will be melted into the custard once it is heated on the stove. This is another way to thicken a custard as it cools.
• Vanilla extract: A vanilla custard filling needs the vanilla flavor!

How to Make Vanilla Cake with Custard Filling

Make the Dough

Step 1: In a large bowl, whisk the sour cream, baking soda, and 2 eggs together. Next, pour in the melted butter and give it a good whisk. Follow this with the sugar and vanilla and continue whisking until combined.

Step 2: Slowly add about 1 cup of flour at a time to the batter, whisking and combining in between each addition. At about the time you add the last bit of flour, you’ll notice it’s hard to continue. Start combining using your hands to make it easier. Do this until all of the flour is added and continue kneading and folding the dough until the flour has dissolved into the dough.

Step 3: You may notice that this cake batter is unlike your traditional cake batter. It is no longer runny, but instead a soft dough, almost like cookie dough that is not sticky once you touch it with a dry finger.

Step 4: Cover the bowl with plastic wrap and allow it to rest for 30 minutes at room temperature. While it’s resting preheat the oven to 400 degrees F.

Bake the Layers

Step 1: Grab a piece of parchment paper, about 2 inches larger than a dinner plate. Take the piece of paper and place the dinner plate on top of it, upside down to make sure it’s got a large enough surface area to cover the plate plus a bit more. Once you have the right size, cut 7 more pieces the same size. Set them aside for a moment.

Step 2: Transfer your dough to a lightly floured surface and divide it into 8 equal pieces. Use your hands to roll each piece into a ball and then place them all back into a bowl. Cover them once more.

Step 3: Take one piece of the parchment paper you cut out earlier and place it onto a clean surface. Drop one of the dough balls onto it and sprinkle with a bit of flour. Using a rolling pin, roll out the dough across the entire surface of the parchment paper (or at least as big as a dinner plate) as flat as you can get it.

Step 4: Place the plate upside down overtop the dough and use the dull side of the butter knife to cut the dough around the plate into a perfect circle, leaving the excess edges right where they are. We will use them later!

Step 5: Place the parchment paper with dough onto a baking sheet and bake for about 4 minutes until slightly golden on top. Allow it to cool on a flat surface and repeat with each of the dough balls until all of the layers are baked and cooled.

Step 6: Remove the excess scraps from around the circles and set them aside.

How to Make Custard Filling

Step 1: Whisk together flour and sugar in a mixing bowl. Beat in the eggs and set the bowl aside.

Step 2: Bring milk to a gentle boil in a saucepan over medium-low heat, whisking continuously. Once it starts bubbling, slowly pour in the egg mixture while continuing to whisk. Once it comes to a gentle boil, simmer on low until it thickens. This should take a couple of minutes.

Step 3: Remove it from the heat and pour in vanilla extract and add butter cubes. Stir until the butter has melted.

Assemble the Cake

Step 1: Place one of the cooled cake rounds onto a cake platter and ladle some of the custard on top. Spread it out evenly so that it coats the entire surface.

Step 2: Top with another cake layer and then another layer of filling. Continue doing this until you've stacked all the layers and finished it with a topping of vanilla custard.

Step 3: Finally, grab those excess pieces of cake you set aside and crush them into coarse crumbs.

Sprinkle them onto the sides and top of the cake for garnish. The filling will do a great job of helping them to stick! Let rest for at least 2 hours before serving, best overnight.

Now, dig in and enjoy!

Make it Ahead

Bake and cool the cake layers then wrap them up in a plastic wrap and place them in the fridge overnight. You can also make the custard and keep it in the fridge until you’re ready to assemble it the next day or make it just before you use it.

If you’ve kept everything in the fridge, bring it to room temperature ahead of time. You can even warm up the custard on the stovetop if you’d like to before spreading it.

Ways to Serve This Vanilla Custard Cake

This impressive cake is elegant enough for all your special occasions! Serve it at baby showers, wedding showers, Easter, Thanksgiving, and Christmas.

It makes a delicious birthday cake or graduation cake too!

Once assembled it’s a round layered cake, so use a cake knife to cut triangle slices as big or as small as you need. Usually, when you’ve got a tall cake your slices can be a bit thinner to make up for it, so that way you can feed more people than you might think.

Notes & Tips for the Best Vanilla Custard Cake

• Storage – Keep covered in the fridge for up to 3–4 days. Custard keeps it moist and delicious.
• Room‑temperature ingredients – Let your eggs, butter, and milk sit out for 20–30 minutes. It helps the custard set perfectly and keeps the cake layers tender.
• Cook custard slowly – Medium/low heat + constant whisking = silky, lump‑free custard.
• Cool layers completely – Don’t stack warm layers; the custard will slide and your cake might get messy.
• Chill before slicing – 2 hours (or overnight) helps the custard firm up so you get clean, beautiful slices.
• Use scraps – Any leftover baked layer pieces? Crush them for a crunchy topping or mix into yogurt for a quick treat.
