- 1 cup granulated sugar – This adds sweetness and helps create a light, fluffy texture in your London Fog Cake.
- 2 large eggs – Eggs help bind the ingredients together and add moisture to the cake.
- 2 cups all-purpose flour – Provides structure; for best results, spoon and level the flour when measuring.
- 1 cup milk (preferably whole) – Whole milk adds creaminess, enhancing the flavor and texture of the cake.
- 2 tbsp Earl Grey tea leaves (or 2 tea bags) – Infuses a delicate tea flavor that is quintessential for this London Fog-inspired cake.
- 1 tbsp baking powder – This leavening agent ensures your cake rises beautifully and has a light crumb.
- 1/2 tsp salt – A pinch of salt balances sweetness and enhances all the flavors in the cake.
- 1 tbsp vanilla extract – Adds depth of flavor; use pure vanilla extract for the best results.
For the Frosting
- 1 cup unsalted butter (softened) – Softened butter is crucial for creating a creamy, spreadable frosting.
- 4 cups powdered sugar – Sweetens and thickens the frosting; sift it for a smoother consistency if desired.
- 2 tbsp heavy cream – Adds richness and helps achieve the perfect spreadable texture in your frosting.
- 1 tbsp vanilla extract – Enhances the flavor profile of the frosting, complementing the cake’s subtle notes.
- 1 tsp dried lavender (for flavor) – Infuses a floral note that ties back to the London Fog inspiration beautifully.
How to Make London Fog Cake
1. Preheat the oven to 350°F (175°C). Grease and flour a 9-inch round cake pan to ensure your cake releases easily after baking.
2. Cream together 1 cup of softened unsalted butter and 1 cup of granulated sugar in a mixing bowl until light and fluffy, about 3-5 minutes.
3. Incorporate 2 large eggs one at a time, mixing well after each addition. This helps achieve a smooth batter that’s perfectly airy.
4. Combine in another bowl, 2 cups of all-purpose flour, 1 tbsp of baking powder, 1/2 tsp of salt, and 2 tbsp of Earl Grey tea leaves. This blend will infuse the cake with lovely flavors.
5. Alternate adding the dry mixture to the wet ingredients with 1 cup of whole milk. Mix until just combined; you want a tender crumb for your London Fog Cake.
6. Stir in 1 tbsp of vanilla extract for that warm aroma that will fill your kitchen while it bakes.
7. Pour the batter into the prepared cake pan and smooth the top with a spatula for an even bake.
8. Bake for 30-35 minutes or until a toothpick inserted into the center comes out clean. The edges should be lightly golden when it’s done!
9. Cool the cake in the pan for 10 minutes before transferring it to a wire rack to cool completely, ensuring it’s ready for frosting.
For the Frosting:
10. Beat 1 cup of softened unsalted butter in a mixing bowl until creamy and smooth, forming the perfect base for your lavender-infused frosting.
11. Gradually add 4 cups of powdered sugar while mixing on low speed until combined. This keeps your kitchen (and you!) free from a sugary cloud.
12. Mix in 2 tbsp of heavy cream, 1 tbsp of vanilla extract, and 1 tsp of dried lavender, then beat on high speed until fluffy and delightful!
13. Frost the cooled cake generously with your lavender frosting using a spatula to coat both the top and sides evenly for that beautiful finish.
14. Decorate with additional dried lavender if desired, adding an elegant touch that complements this delightful dessert beautifully!
Optional: Garnish with fresh lavender sprigs for an extra pop of color.

Expert Tips
- Butter Temperature: Ensure your butter is softened but not melted; this creates a fluffy texture in your London Fog Cake.
- Egg Addition: Add the eggs one at a time and mix well. This helps to incorporate air, giving your cake a light crumb.
- Dry Ingredients Mix: Sift together flour, baking powder, salt, and Earl Grey tea leaves to avoid clumps and ensure even flavor distribution.
- Avoid Overmixing: Combine wet and dry ingredients until just mixed; overmixing can result in a dense cake instead of a soft London Fog Cake.
- Cooling Time: Allow the cake to cool completely before frosting. This prevents the lavender frosting from melting into the cake.
- Lavender Balance: Use dried lavender sparingly in the frosting; too much can overpower the subtle tea flavors of your London Fog Cake.
How to Store London Fog Cake

- Room Temperature: Keep the London Fog Cake in an airtight container for up to 3 days. This helps maintain its moist texture and delightful flavor.
- Fridge: For longer freshness, store the cake in the fridge for up to 1 week. Wrap it tightly in plastic wrap or place it in an airtight container to prevent drying out.
- Freezer: You can freeze the cake for up to 3 months. Wrap slices individually in plastic wrap and then place them in a freezer-safe bag for best results.

London Fog Cake Your Way
Feel free to let your creativity shine by customizing this delightful recipe to suit your taste preferences!
- Gluten-Free: Substitute all-purpose flour with a 1:1 gluten-free baking blend for a deliciously accommodating treat. This change allows everyone to enjoy the flavors without compromising on texture. The cake will remain soft and moist, ensuring it’s just as satisfying.
- Lavender-Free: If lavender isn’t your thing, skip it in the frosting and opt for lemon zest instead. This twist adds a bright, citrusy note that complements the Earl Grey beautifully. The refreshing flavor will transport you to a sunny afternoon tea.
- Vegan: Replace butter with coconut oil and eggs with flaxseed meal (1 tbsp flaxseed + 2.5 tbsp water per egg). The result is a cake that’s equally moist and flavorful, perfect for those following a plant-based diet. You won’t miss the dairy at all!
- Chai Spice Infusion: Swap Earl Grey tea for chai tea bags for a warm, spiced version of this cake. Each bite will be filled with cozy notes of cinnamon and cardamom, making it perfect for fall gatherings or chilly evenings.
- Chocolate Drizzle: For a decadent touch, melt some dark chocolate and drizzle it over the frosted cake. This addition elevates the dessert and adds a rich contrast to the floral notes of the lavender frosting. It’s a delightful surprise for chocolate lovers!
- Nutty Crunch: Fold in 1 cup of finely chopped walnuts or almonds into the batter before baking for added texture and flavor. The nuts provide a satisfying crunch that pairs well with the soft cake, creating an enjoyable bite every time.
- Honey Sweetened: Replace granulated sugar with honey in both the cake and frosting (reduce milk slightly). This swap introduces natural sweetness while enhancing depth of flavor. The result is a beautifully moist cake with earthy undertones.
- Citrus Zing: Add 1 tablespoon of orange zest to both the batter and frosting for a zesty kick that brightens the overall taste. The citrus notes bring an unexpected freshness that will leave your palate dancing with delight!

London Fog Cake Recipe FAQs
How can I ensure my London Fog Cake turns out moist?
To keep your cake moist, make sure to use whole milk and don’t overmix the batter after adding the dry ingredients. Mix until just combined; this will help maintain a tender crumb. Additionally, incorporating the wet and dry ingredients in alternating batches helps achieve that perfect texture.
Can I use a different type of tea instead of Earl Grey?
Absolutely! While Earl Grey provides that signature flavor with its bergamot notes, you can experiment with other loose leaf teas such as chamomile or English breakfast for a unique twist. Just remember to adjust the amount based on the strength of the tea you’re using.
What’s the best way to store leftover cake?
Store any leftover London Fog Cake in an airtight container at room temperature for up to 3 days. If you want to keep it fresh longer, you can refrigerate it where it will last about a week. Just be sure to bring it back to room temperature before serving for optimal flavor!
Can I freeze the London Fog Cake?
Yes, you can freeze your London Fog Cake! Simply wrap it tightly in plastic wrap and then in aluminum foil to prevent freezer burn. It will keep well in the freezer for up to 2 months. When you’re ready to enjoy it again, thaw it in the refrigerator overnight before frosting and serving.
What should I do if my frosting is too thick?
If your lavender frosting turns out too thick, simply add a splash of heavy cream—about 1 tablespoon at a time—until it reaches your desired consistency. This will help achieve a smooth and spreadable texture without compromising the delightful lavender flavor.
