This Earl Grey Cake Lemon Curd cake is everything you have always dreamed of. It is light and fluffy and topped with light whipped cream and a tasty lemon curd.
Preheat Oven to 350F. Line an 8x8 pan with parchment paper.
Add the measured milk in a heat-safe measuring cup and heat in the microwave for 30 seconds or until it's hot to the touch. Add in the earl grey tea bag and allow it to steep for at least 10 minutes. Once 10 minutes is over press the bag to release as much of the flavors as possible and throw away the bag and if using loose tea leaves use a fine-mesh sieve to catch the remaining tea leaves.
With a large sized bowl add the softened butter, vegetable oil, and half the sugar. Cream the butter and sugar until fluffy and then add the egg yolk and sour cream. Mix the ingredients until combined, then scrape the bowl's sides with a rubber spatula.
Add all the dry ingredients to a mixing bowl and cut the tea sachets to add the tea leaves into the dry ingredients. If the tea leaves are too big you may have to grind them until it's finer.
Alternate the steeped milk and the dry ingredients in thirds starting with the dry and then the wet.
In a clean medium-sized bowl add the two eggs whites and whisk on high until bubbles form. Once small bubbles form slowly add in the remaining sugar. Beat the meringue until stiff peaks.
Fold half the egg whites into the batter until there are no more meringue streaks and then fold in the remaining half carefully making sure not to over-mix and deflate the batter.
Pour the cake batter into the prepared pan and bake for 18 to 20 minutes.
Once the cake is ready flip the cake over on a wire rack to prevent the cake from deflating.
Allow the cake to cool.
Whipped Frosting
Add cream cheese and powdered sugar to your stand mixer with a paddle attachment. Cream until it comes it smooth.
Add in ⅓ of the heavy cream and then mix on low speed until it comes together. The mixture should not be lumpy. Once it's all combined add in the remaining heavy cream and vanilla extract.
Change out the paddle attachment to the whisk attachment and whisk on high until stiff peaks form.
