Add milk to a small saucepan over medium heat. Bring the milk to a simmer then immediately remove from heat. Place the tea bags into the milk and gently stir. Place a piece of plastic over the surface of the milk and place into the fridge to cool and steep for about 2 hours.

Preheat oven to 350°F, and prepare two 9” springform cake pans with oil and parchment rounds. In a large sized mixing bowl, add the flour, baking powder, and salt, then whisk together to combine.

In a stand mixer fitted with the paddle attachment, add eggs, sugar, and vanilla. Beat on high for around 5 minutes, the mixture should look thick, fluffy, and be tripled in volume. Scrape down the sides of the bowl and then slowly drizzle in the oil while on medium-low speed. After all the oil has been added, beat on high for an additional minute.

On low, add the dry mixture to the stand mixer, mixing until just combined. Add in the tea-infused milk and mix only until the batter becomes smooth. Add the batter evenly to the cake pans, then bake in the oven for around 45-50 minutes, or until a toothpick comes out clean. Allow to cool completely before stacking and frosting.

Place egg whites, sugar, and honey, into a metal bowl and place over top of a pot of simmering water (ensuring the water is not touching the metal bowl). Whisk the mixture constantly until it reaches 165°F or 70°C. Remove from heat immediately and place into the stand mixer.

Using the whip attachment, turn the stand mixer onto high and beat the meringue for about 7 minutes. The meringue should have stiff peaks.

Turn the stand mixer to low and add in the butter 2 tbsp at a time, allowing each addition to incorporate a bit before the next. When all the butter has been added turn the stand mixer back onto high and beat until the buttercream looks smooth. (It may look curdled and soupy at one point, but just keep beating).

Add vanilla and salt to the buttercream and beat to combine.

Level off each of the cake layers to remove any doming from the cakes.

Place one cake layer onto your serving plate or onto a cardboard cake circle. Spread an even layer of buttercream, about 1" to 1 ½” thick, across the top of the layer.

Add the second layer on top, then repeat step 2. Decorate the top with anything you’d like!
