Ingredients

Scale

For the Earl Grey Cake

  • 3 tbsp (12 g) Earl Grey tea
  • 1 tbsp (2 g) culinary lavender
  • 2 1/4 cups (282 g) all-purpose flour, spooned and leveled
  • 1 1/2 tsp baking powder
  • 1/4 tsp baking soda
  • 1/2 tsp salt
  • 10 tbsp (140 g) unsalted butter, softened
  • 1 1/2 cups (300 g) granulated white sugar
  • 3 eggs, at room temperature
  • 1 tbsp vanilla bean paste
  • 1 cup (240 ml) buttermilk
  • 1/2 cup (120 ml) whole milk

For the Earl Grey Milk Soak

  • 2 tbsp (8 g) Earl Grey tea
  • 1/2 tbsp (1 g) culinary lavender
  • 1/2 cup (150 g) sweetened condensed milk
  • 1/2 tsp vanilla bean paste

For the Lavender Cream Cheese Frosting

  • 1 tbsp (2 g) culinary lavender
  • 1 cup (224 g) unsalted butter, softened
  • 8 oz (226 g) cream cheese, cold
  • 2 cups (260 g) powdered sugar
  • 1 tsp vanilla bean paste
  • purple food coloring (optional)

Instructions

  1. Preheat and Prepare Pan: Preheat your oven to 350°F (175°C). Grease a 9×9 inch light metal baking pan and line it with parchment paper to ensure the cake releases easily after baking.
  2. Grind Tea and Lavender: Place Earl Grey tea and culinary lavender in a food processor and pulse until finely ground. Pass the mixture through a sieve to remove any large bits, ensuring a smooth texture in the cake.
  3. Mix Dry Ingredients: In a medium bowl, whisk together the flour, ground Earl Grey and lavender mixture, baking powder, baking soda, and salt. Set aside until needed.
  4. Cream Butter and Sugar: In a large bowl, use an electric mixer on high speed to cream the softened butter and granulated sugar together for 2 minutes until light and fluffy.
  5. Add Eggs and Vanilla: Add the eggs one at a time along with the vanilla bean paste, mixing on medium speed until the batter becomes pale and smooth, about 1 minute.
  6. Combine Wet and Dry Ingredients: Gradually add the buttermilk and the dry flour mixture to the batter, mixing on low speed until fully combined. Scrape down the bowl sides with a rubber spatula as needed to ensure an even batter.
  7. Bake the Cake: Pour the smooth batter into the prepared pan and bake for 38-44 minutes, or until a toothpick inserted into the center comes out clean.
  8. Cool the Cake: Let the cake cool in the pan on a wire rack for 30 minutes. Then gently lift it out using the parchment paper and allow it to cool completely on the wire rack.
  9. Prepare Earl Grey Milk Soak: Add whole milk to a small saucepan and heat over low until steaming. Remove from heat and steep Earl Grey tea and culinary lavender for 15 minutes. Strain the mixture to remove solids and allow the milk to cool.
  10. Mix Milk Soak Ingredients: Transfer the cooled Earl Grey milk to a pourable container, stir in the sweetened condensed milk and vanilla bean paste, then set aside.
  11. Grind Lavender for Frosting: Pulse the culinary lavender in a food processor until finely ground and sift to remove any large pieces.
  12. Make Lavender Cream Cheese Frosting: Using an electric mixer, beat the softened butter on high speed until pale and fluffy (about 5 minutes). Add the cold cream cheese and beat until fluffy, about 1 minute. Slowly add powdered sugar, ground lavender, and vanilla bean paste mixing on low until combined, then on high for 1 minute more. Add purple food coloring if desired and mix to incorporate.
  13. Prepare Cake for Soaking: Once the cake is completely cooled, carefully slice off a very thin layer from the top to help the soak absorb better. Transfer the cake to a serving plate and poke holes over the surface with a wooden stick or the handle of a spoon.
  14. Soak the Cake: Slowly pour the Earl Grey milk mixture evenly over the cake, allowing it to soak in through the holes. Be patient to ensure the liquid is absorbed without making the cake soggy.
  15. Frost the Cake: Spread a thick, even layer of the lavender cream cheese frosting over the soaked cake using an offset spatula.
  16. Serve: Cut the cake into 16 slices and serve, enjoying the delicate flavors and tender texture.

Notes

  • For best results, use good-quality Earl Grey tea with strong bergamot flavor.
  • Be sure to sift ground tea and lavender to avoid gritty bits in the cake and frosting.
  • The cake can be baked a day in advance and stored at room temperature, wrapped tightly.
  • Refrigerate the assembled cake if not serving immediately to keep the cream cheese frosting fresh.
  • Adjust the amount of lavender in frosting to your taste, but be cautious as it can easily overpower.
