Two Cups Flour

Genoise Cake
2 Prepare three 6 inch cake pans with non-stick spray and line the bottom with parchment paper.
3 Preheat oven to 350 F (180 C).
4 In the bowl of a stand mixer fitted with whisk attachment on medium high speed whip eggs, sugar, salt and vanilla until light and fluffy. (about 10 minutes) Mixture should triple in volume. 
5 Remove bowl for mixer and carefully fold in sifted cake flour a third at a time. Divide batter evenly between all three cake pans.
6 Place cake pans on a cookie sheet and bake on middle rack for 20-22 minutes until slightly golden on the edges.
7 Place cakes on cooling rack to cool completely before removing from cake pans.
Cream Frosting
10 In bowl of stand mixer fitted with whisk attachment on medium speed, whip mascarpone and cream cheese until fluffy and smooth. 
11 Add Spice Cream Rum and one cup of powdered sugar. Mix until incorporated.
12 Scrape bottom and sides of bowl as needed.
13 Add remaining cups of powdered sugar one at a time and mix until thick and smooth.
Espresso Soak and Assemble
16 Place one cooled layer of cake onto desired serving plate. 
17 Brew one cup of fresh espresso and grab a pastry brush.

19 Next, cover the top of the first cake layer with a generous layer of Coconut Spiced Rum Cream Frosting.
20 Repeat espresso soak and frosting layer with remaining two cake layers.
21 Apply a think layer of frosting around sides of cake and smooth with offset spatula or bench scraper.
