Creating the London Fog Cake can be a straightforward process when you follow these steps:

1. Preheat Your Oven: Begin by preheating your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans.
2. Infuse Milk: In a saucepan, heat the milk on low heat until warm. Add the Earl Grey tea leaves (or tea bags), allowing them to steep for about 10 minutes. Remove tea and set aside to cool.
3. Mix Dry Ingredients: In a large bowl, sift together the flour, baking powder, and salt.
4. Cream Butter and Sugar: In another bowl, cream together the softened butter and granulated sugar until light and fluffy.
5. Add Eggs: Beat in the eggs, one at a time, ensuring each is fully incorporated before adding the next.
6. Combine Ingredients: Gradually mix the dry ingredients into the butter-sugar mixture, alternating with the brewed Earl Grey milk. Start and finish with the dry ingredients.
7. Stir in Vanilla: Add the vanilla extract and mix until just combined. Be careful not to overmix.
8. Pour Batter: Divide the batter evenly between the two prepared cake pans.
9. Bake: Bake in the preheated oven for 30-35 minutes or until a toothpick inserted into the center comes out clean.
10. Cool: Remove from the oven and allow the cakes to cool in their pans for 20 minutes before transferring them to wire racks to cool completely.
11. Make Frosting: While cooling, whip the heavy cream until soft peaks form. Add sugar to taste, then frost the cooled cakes.
12. Assemble Cake: Once cooled, place one layer on a serving platter. Spread some frosting on top and place the second layer on top. Frost the top and sides of the cake as desired.

These steps will guide you in creating the delicious London Fog Cake with ease.
