Preheat oven to 350°F (175°C) and prepare two 8-inch round cake pans with parchment paper.
Whisk together flour, sugar, organic cocoa powder, baking powder, baking soda, and salt in a large bowl.
Add milk, oil, eggs, and vanilla bean paste. Beat on medium speed for 2 minutes.
Carefully stir in the boiling water until just combined. The batter will be thin.
Divide batter evenly between pans and bake for 30-35 minutes until a toothpick comes out clean. Cool completely.
To make the buttercream, beat softened butter until creamy. Gradually add powdered sugar, cocoa powder, heavy cream, vanilla, and salt. Beat until fluffy.
Melt premium baking chocolate and coconut oil together. Dip completely dry strawberries into the chocolate and let set on parchment paper.
Level cooled cakes, stack with buttercream in the center, and frost the exterior. Arrange the set chocolate strawberries on top before serving.
