- Allow the cakes to cool in their pans for ten minutes. Then carefully transfer to wire racks to cool completely before frosting.

- Gently melt chocolate chips with honey and heavy cream either in short bursts in the microwave or using a double boiler. Let cool slightly until it thickens.
- Make The Frosting Base:
- Beat roomtemperature butter in a large bowl until light and fluffy creating a smooth base for the frosting.

- Place one cake layer on your serving plate and spread a generous amount of frosting on top.
- Stack And Decorate:
- Repeat with remaining layers then cover the entire cake's top and sides with the remaining frosting. Decorate as desired with chocolate shavings or sprinkles.

The frosting is my favorite part. It reminds me of the chocolate birthday cakes my grandmother used to bake. We would sneak spoonfuls before the cake was even assembled creating warm memories that linger with every bite.
