Preheat the oven to 350F. In a small saucepan melt the butter in the medium heat. Add the cocoa powder and stir with a spoon.
Add 1 cup of boiling water. Let it boil for 30 seconds then remove from the heat and set aside.
In a big bowl combine flour, salt and sugar.
Pour the cocoa mixture and stir until half way combined.
In a different bowl combine buttermilk, eggs, vanilla and baking soda mix until smooth.
Mix buttermilk mixture into cocoa/flour mixture then mix until smooth
Butter two 9-in round cake pans add parchment paper then pour the batter equally into the pans. Bake for 20 minutes or until toothpick comes out clean when inserted in the center. Let it cool.
Now lets prepare our strawberry topping: wash, hull and slice strawberries. Place in the bowl and add sugar and vanilla, stir until ingredients are combined. Let it sit and marinate for 15 minutes.
While strawberries are marinating with a stand mixer whisk heavy cream with powdered sugar until stiff.
Lets decorate our cake: first peel off the parchment paper from the bottom of the cakes. Place first cake layer upside down on a flat plate or a cake stand. Spread 3/4 cup of Nutella follow by half of whipped cream and half of the strawberry topping.
Repeat with a second cake layer. Cut a slice and enjoy the yummy goodness!
