Basic Tools & Equipment Needed
- 9×9 inch light metal baking pan
- Parchment paper
- Food processor or spice grinder
- Fine-mesh sieve
- Electric hand mixer or stand mixer
- Small saucepan
- Mixing bowls
Step-by-Step Instructions
1. Prep the Tea and Lavender
Start by preheating the oven to 350°F (175°C). Grease a 9×9 inch baking pan and line it with parchment paper for easy removal. Place the Earl Grey tea and culinary lavender into a food processor. Pulse until they are finely ground. Pass this mixture through a fine-mesh sieve to remove any large, woody bits.
2. Mix the Dry Ingredients
In a medium-sized bowl, whisk together the all-purpose flour, the ground tea and lavender mixture, baking powder, baking soda, and salt. Set this aside for later.
3. Cream Butter and Sugar
In a large mixing bowl, add the softened unsalted butter and granulated sugar. Using an electric mixer on high speed, cream them together for about 2 minutes until the mixture looks pale and fluffy.

4. Incorporate Wet Ingredients
Add the eggs one at a time, followed by the vanilla bean paste. Mix on medium speed for about 1 minute until the batter is smooth and light in color.
5. Combine and Bake
Switch the mixer to low speed. Gradually add the buttermilk and the dry flour mixture, alternating between the two. Mix just until everything is combined. Pour the batter into your prepared pan and smooth the top. Bake for about 30-35 minutes. Let the cake cool in the pan for about 20 minutes before transferring it to a wire rack.
6. Prepare the Milk Soak
Heat the whole milk in a small saucepan over low heat until steaming. Stir in the Earl Grey tea and lavender. Let it steep for 15 minutes, then strain it through a sieve. Stir in the sweetened condensed milk and vanilla bean paste. Set this aside.

7. Make the Lavender Frosting
Pulse the lavender for the frosting in a food processor until fine and sift it. In a large bowl, beat the softened butter for 5 minutes until very light and fluffy. Add the cold cream cheese and beat for another minute. Sift in the powdered sugar, then add the ground lavender and vanilla. Mix on low until combined, then on high for 1 minute.
8. Assemble the Cake
Once the cake is cool, use a sharp knife to trim a very thin layer off the top. Poke holes across the surface of the cake with a fork. Slowly pour the milk soak over the top, letting it sink in. Finally, spread the lavender cream cheese frosting over the top of the cake.

The texture of this cake is uniquely soft, much like the melt-in-your-mouth crumb found in a traditional French Butter Cake Recipe – Rich, Buttery Perfection. While the London Fog Cake focuses on tea and floral notes, both recipes celebrate the beauty of high-quality butter and a tender sponge
Helpful Tips & Variations
- Measure Accurately: Use the “spoon and level” method for your flour. Scooping directly with a measuring cup can pack the flour down, leading to a dry cake.
- Temperature Matters: Ensure your eggs and buttermilk are at room temperature. This prevents the butter from curdling.
- Don’t Over-steep: When making the milk soak, don’t leave the tea in for more than 15 minutes, or it might become bitter.
- Lavender Strength: Culinary lavender can be strong. If you prefer a milder floral note, you can reduce the amount by half.
- Vanilla Swap: If you don’t have vanilla bean paste, you can use an equal amount of pure vanilla extract.

Storage & Serving
Storage
Because this cake has a cream cheese frosting and a milk soak, it must be kept refrigerated. Place the cake in an airtight container or cover the pan tightly with plastic wrap. It will stay fresh for up to 4 days.
Serving Ideas
This cake is stunning on its own, but you can elevate the presentation by sprinkling a few dried lavender buds or extra tea leaves on top. It pairs beautifully with a glass of cold milk or a fresh cup of decaf tea.
Frequently Asked Questions (FAQs)
- Can I use tea bags instead of loose leaf tea? Yes! Simply cut open the tea bags and use the leaves inside. About 5-6 tea bags should equal the 3 tablespoons needed.
- What is culinary lavender? Culinary lavender is a specific variety processed for eating, which has a better flavor profile than craft store lavender.
- Can I make this cake in a round pan? Yes, you can use two 8-inch round pans. Keep an eye on the baking time as it may be shorter (around 25 minutes).
- Why is my frosting runny? This often happens if the butter is too soft or the cream cheese is too warm. Ensure your cream cheese is cold.
- Is the purple food coloring necessary? Not at all! The frosting will be a natural creamy white without it.
- Can I use regular milk instead of buttermilk? Buttermilk provides acidity for a better rise. If you don’t have it, add 1 tablespoon of lemon juice to 1 cup of milk.
- Do I have to trim the top of the cake? Trimming the top allows the milk soak to absorb much better.
- Can I freeze this cake? You can freeze the un-frosted cake layers. It is best to add the soak and frosting fresh after thawing.
- How do I get a strong Earl Grey flavor? Sifting the ground tea directly into the dry ingredients ensures the flavor is distributed through every bite.
- What does “creaming” the butter and sugar mean? It means beating them together until the sugar starts to dissolve and the butter becomes light and airy.
Conclusion
This London Fog Cake is a delightful departure from standard vanilla or chocolate cakes. The subtle citrus of the bergamot and the calming scent of lavender create a dessert that is truly memorable. Give this recipe a try next time you want to bake something a little extra special. The steps are simple, and the results are incredibly rewarding.
