Let’s Bake This Beauty: Step-by-Step Lambeth Cake Recipe
Alright, sleeves up. This Lambeth cake recipe is like building a house—start with a strong foundation, layer on the charm, and finish with the wow factor. And yes, it’s easier than it looks.
Step 1: Preheat and Prep
Preheat your oven to a moderate temperature of 350°F (175°C) to ensure an even bake throughout, and take a moment to thoroughly prepare your cake pans — coating them with a light layer of fat to prevent sticking, then carefully placing a round of parchment paper at the base. This extra step saves you from the frustration of trying to pry delicate cake layers free from the pan later on.
Step 2: Sift and Mix the Dry Ingredients
In a large bowl, sift together:
- 2 ½ cups of cake flour (or all-purpose if that’s what you’ve got)
- 1 tsp baking powder
- ½ tsp baking soda
- ½ tsp kosher salt
Give it a quick whisk to combine. This keeps your cake light and airy instead of dense and doughy.
Step 3: Cream the Butter and Sugar
In a separate bowl, beat ½ cup of softened salted butter until it’s smooth and creamy. Slowly add in 2 cups of granulated sugar, a little at a time, mixing until it’s fluffy and light—like snowdrifts in a mixing bowl. This step is what helps the cake rise and stay soft.
Step 4: Add Egg Whites and Vanilla
Mix in 4 egg whites, one at a time, blending well after each addition. Add 1 tsp vanilla extract and give it a good stir.
(Pro tip: using just the egg whites keeps the cake super light and white. Save the yolks for something fun like homemade pudding.)
Step 5: Alternate Dry Ingredients and Milk
Now, this part’s like a little baking dance—add the dry ingredients in three parts, alternating with 1⅓ cups of whole milk. Start and end with the dry mix. Stir just until combined; overmixing is a no-no unless you like your cake chewy (which we don’t).
Step 6: Bake the Layers
Pour the batter evenly into your greased pans. Bake for 25–30 minutes, or until a toothpick poked in the center comes out clean. As they bake, let the sweet aroma of vanilla fill your kitchen—it’s a little moment of bliss.
Step 7: Cool Completely
Once the cakes are baked, let them sit in their pans for about 10 minutes. Carefully place them on a wire rack and allow them to cool completely. As tempting as it may be, resist the urge to frost while warm—unless you’re going for a gooey, melty mess!
Step 8: Make the Blackberry Buttercream
In a mixing bowl, whip 1¼ cups of softened salted butter until it’s silky and smooth. Slowly add 5 to 6 cups of powdered sugar, mixing as you go. Add in 2 to 3 tablespoons of milk to adjust the consistency. Finally, blend in ¼ cup of blackberry jelly until the color is dreamy and the flavor is bright and tangy. This is the frosting you’ll be swooning over.
Step 9: Whip Up the Vanilla Buttercream
For those delicate Lambeth-style details, mix:
- ¼ cup of salted butter (softened)
- 2 to 3 cups of powdered sugar
- 1 to 2 tablespoons of milk
- ½ tsp vanilla extract
Beat until the frosting is smooth and firm enough to hold its shape—ideal for that crisp, classic piped look.
Step 10: Assemble the Layers
Once your Lambeth cake layers are cooled and leveled, begin assembly by spreading a generous 6-ounce layer of blackberry jelly between each tier. Then, coat the entire cake with luscious blackberry buttercream. Smooth it out with an offset spatula—it doesn’t have to be flawless, just filled with love.
Step 11: Decorate Like a Pro
Fill your piping bags with the vanilla buttercream and select a few piping tips to play with—keep it simple if you’re just getting started. Practice on a plate if you want. Now let your creativity shine—decorate to your heart’s delight. Ruffles, dots, scrolls, swoops—this is your cake’s moment to shine.
Nutrition Info: What’s Inside This Sweet Slice of Lambeth Cake
Let’s be honest—Lambeth cake isn’t exactly trying to win “health food of the year,” but that’s not why we bake it, right? This beauty is a celebration cake. It’s rich, buttery, and unapologetically sweet—the kind of dessert you slice with a little ceremony and a whole lot of excitement.
That said, it’s still helpful to know what you’re working with nutritionally, especially if you’re tracking macros, feeding kids, or just curious about what’s fueling your cake craving. While this isn’t an everyday snack (unless you’ve got a serious sweet tooth), it’s absolutely worth the splurge for birthdays, holidays, or when you just need a little edible joy.
The numbers below are based on a standard slice (1 of 12 servings), frosted and filled as described in the recipe. Keep in mind, exact values might vary depending on your specific ingredients—especially if you go heavy on the frosting or add extra decorations (no judgment here!).
Still, the Lambeth cake offers a decent punch of energy, a small bit of protein from the egg whites, and even a little calcium and iron. If you want to lighten things up, you could opt for a thinner frosting layer or substitute a portion of the sugar with a lower-calorie sweetener—but really, this cake is made for moments of indulgence.

Pro Tips for a Perfect Lambeth Cake
Let’s be real—this Lambeth cake is a bit of a show-off. It’s fancy. It’s dramatic. And yes, it has a flair for the theatrical (just like Aunt Carol at family reunions). But here’s the thing: underneath all that frosting and flair, it’s actually a manageable recipe—if you follow a few smart moves.
Here’s how to make your Lambeth cake look like it came straight out of a baking competition:
1. Room Temp Is Your Best Friend
Make sure your milk, eggs and butter are all at room temperature. Cold ingredients don’t mix well and can leave you with a lumpy batter—and no one wants that kind of drama.
2. Level Those Layers
Use a serrated knife or cake leveler to trim the tops off your cake layers. Flat layers = no wobbling tower.
3. Chill Before You Swirl
Pop your Lambeth cake in the fridge after you crumb coat it. That quick chill (30–60 minutes) helps your final frosting layer stick better and keeps things clean when piping those elegant Lambeth-style swirls.
4. Start Simple with Piping
If you’re new to piping, don’t go full Picasso just yet. Start with basic shell or rosette tips (Wilton 1M or 2D are great!) and practice on parchment paper before diving into your Lambeth cake.
5. Use a Turntable if You Have One
It’s not mandatory, but it makes frosting and decorating so much easier. Plus, you get to feel like a baking pro doing that little spin move.
6. Blackberry Jelly = Secret Flavor Bomb
Don’t skip the blackberry jelly—it adds a juicy, slightly tart punch that balances out the sweetness of the buttercream.
7. Decorate in Layers
If you’re nervous, decorate in stages. Pipe some details, take a break, come back with fresh eyes. (And maybe a cup of coffee.)
8. Don’t Chase Perfection
The beauty of a Lambeth cake is in its personality. Imperfect swirls? Off-center rosettes? All part of the charm. Just have fun with it!
My Personal Lambeth Cake Story
The first time I made a Lambeth cake, I had no clue what I was getting into. I was scrolling online looking for a birthday cake idea for my mom—something vintage, elegant, and, well, a little extra (because that’s her style).
Let’s just say… my kitchen looked like a frosting explosion by the end of it. I had piping tips I didn’t know how to use, food coloring on my elbow, and a Lambeth cake that leaned ever so slightly to the left. But when I brought it out, my mom gasped—like, the good kind of gasp.
Turns out, the Lambeth cake didn’t need to be perfect. It needed to be personal. The delicate swirls, the blackberry filling, the old-school vibe—it all reminded her of the cakes her grandmother used to make.
Since then, it’s become our little tradition. We make one together every year—she still gasps, I still lean into the mess, and we always sneak a spoonful of buttercream before the guests arrive.
Storage Tips For Lambeth Cake
Alright, so you’ve wowed your guests and maybe even earned a standing ovation. But what about the leftovers (if you’re lucky enough to have any)?
Here’s how to keep your Lambeth cake tasting bakery-fresh:
Room Temperature:
If your kitchen isn’t too warm (below 70°F), you can keep the cake covered on the counter for up to 2 days. Just make sure it’s in a cake dome or tightly wrapped to prevent it from drying out.
Refrigerator:
To keep it fresh longer, pop the Lambeth cake in the fridge. It’ll stay good for about 4–5 days. Wrap it in plastic wrap or store it in an airtight container to protect those lovely layers.
Tip: Let the Lambeth cake sit out for about 30 minutes before serving—cold cake can mute the flavors, and we’re not about that life.
Freezer:
Want to save it for a rainy day (or a midnight craving)? You totally can!
- Slice the Lambeth cake into portions.
- Wrap each piece in plastic wrap and foil.
- Freeze for up to 2 months.
- Thaw overnight in the fridge or a few hours at room temp.
And hey, if you find yourself eating it straight from the freezer like a secret stash? No judgment. That’s between you and the cake.
