Banana Cake
2 Preheat your oven to 350 degrees Fahrenheit.
4 Combine all your dry ingredients – flour, baking soda and salt in a medium-sized bowl, give it a whisk and set aside.
6 Add the coconut oil and sugars into a large bowl and beat together until well mixed.
34 Add egg, then scrape the bowl making sure ingredients are mixed well. Then add the sour cream and vanilla, mix and finally add the mashed bananas mixing until combined.
10 Add the dry ingredients, and mix until just combined.
30 Pour batter into a greased 6-inch cake pan and bake for 40-45 minutes. For a shorter single-layer cake, you can always instead bake your cake in an 8-inch cake pan for a shorter amount of time.  Make sure to check that the cake is fully baked with a toothpick before removing it from the oven and allow the cake to cool completely before assembling. 
Brown Butter Buttercream
31 Add your sugar and egg whites to the bowl of a stand mixer and place over a saucepan of boiling water.
18 Make sure that your bowl is not touching the hot water! Your goal is to simply whisk the egg whites and sugar together over a gentle heat until the sugar has completely dissolved, then attach your bowl back to the standing mixer. The temperature should read 165 F before it’s ready to be removed from the heat.
20 Whisk mixture starting at a low speed and gradually increase until soft peaks form and the mixture has cooled. Switch to using your paddle attachment, then start adding your brown butter and regular butter bit by bit.
32 When you’ve reached the point where the buttercream is glossy and smooth, stop the mixer and set it aside for assembling.
Assembly
33 Add as much of your brown butter buttercream on top of the cake and spread evenly. Utilizing a spoon or an offset spatula, create swirls and swoops to your liking into the buttercream! I used a small spoon to create the swirls you see below. Add the decoration of your liking on top! I added a couple of different layers of toppings, starting with some chopped pecans and walnuts, cacao nibs and then whole nuts to add for a pleasing aesthetic.
