Step 1: Steep the Earl Grey Milk Foundation
Begin by creating the flavor base. In a small saucepan, bring the whole milk to a gentle simmer over medium heat. Do not let it boil. Remove the pan from the heat, add the loose-leaf Earl Grey tea, cover with a lid, and let it steep for exactly 15 minutes. Steeping longer can release tannins that make the milk bitter. Strain the milk through a fine-mesh sieve into a measuring cup, pressing on the tea leaves to extract all the liquid and oils. Discard the leaves and let the milk cool to room temperature. You should have exactly 1 cup of milk; if you are short, top it off with a splash of plain whole milk.

Preheat your oven to 350°F (175°C). Grease your two 8-inch cake pans and line the bottoms with parchment paper. In a large mixing bowl, thoroughly whisk together the sifted all-purpose flour, baking powder, baking soda, salt, and the optional finely ground Earl Grey tea leaves. Whisking the dry ingredients ensures an even distribution of leavening agents, which prevents a lopsided or sinking cake.Step 3: Cream the Butter and Sugar
In the bowl of your stand mixer fitted with the paddle attachment, beat the softened butter on medium-high speed for 2 minutes until it is smooth and creamy. Gradually add the granulated sugar and continue to beat for another 3 to 4 minutes until the mixture is exceptionally pale, light, and fluffy. This step is critical as it forces air into the batter, which expands in the oven to give the cake its lift.

Reduce the mixer speed to medium-low. Add the room-temperature eggs one at a time, ensuring each egg is fully incorporated before adding the next. Scrape down the sides and bottom of the bowl with a rubber spatula after the second egg. Add the vanilla bean paste and mix until combined. Using room-temperature eggs prevents the butter from seizing and breaking the emulsion.Step 5: Incorporate the Wet and Dry Ingredients
With the mixer on the lowest speed, add the dry flour mixture in three parts, alternating with the cooled Earl Grey infused milk in two parts (begin and end with the dry ingredients). Mix only until just combined; do not overmix. Overmixing develops the gluten in the flour, resulting in a dense, tough cake rather than a tender sponge. Mastering this delicate folding process is one of the many cake baking tips and techniques that separate amateur home bakers from seasoned professionals.Step 6: Bake the Cake Layers
Divide the fragrant batter evenly between the two prepared cake pans. Smooth the tops with a spatula. Bake for 30 to 35 minutes, or until a toothpick inserted into the center comes out clean and the edges pull slightly away from the sides of the pan. Allow the cakes to cool in their pans for 15 minutes before carefully turning them out onto wire cooling racks to cool completely to room temperature.Step 7: Prepare the London Fog Buttercream and Assemble
While the cakes cool, prepare your frosting. Beat the softened butter on medium-high speed until pale and creamy (about 5 minutes). Reduce the speed to low and gradually add the sifted powdered sugar. Once incorporated, add the vanilla bean paste, the pinch of salt, and 3 tablespoons of the leftover Earl Grey milk. Beat on high speed for an additional 3 minutes until the frosting is light, fluffy, and spreadable.
