how to make Frost a Cake with Smooth Buttercream
Ingredients :
- Baked cake layers (size / flavors of your choice)
- Frosting (flavor / color of your choice)
Directions :
-
Level your cake layers: Start by trimming the tops of your baked cake layers with a serrated knife. This step ensures that your cake layers are even and flat, which makes stacking easier.


-
Stack your cake layers: Place one layer of cake on a serving platter or a cake stand. Spread a layer of buttercream frosting on top before adding the next layer. Continue this with all the layers, making sure to use more frosting between each one.



-
Add a Crumb coat + Chill your cake: Once your layers are stacked, apply a thin layer of frosting around the entire cake. This is called a crumb coat. It seals in crumbs and helps create a smooth final layer. Chill the cake in the refrigerator for about 30 minutes.
-
Tip that helped me the most: Keep your buttercream slightly warm before applying it to the cake. If your frosting is too cold, it can become difficult to spread smoothly.
-
Add the final frosting layer: After chilling, take the cake out and apply a thicker layer of buttercream all around. Use a spatula to spread the frosting smoothly. Don’t worry about perfection yet!
-
Smooth the frosting – and get that smooth sharp edge at the top!: Use a bench scraper or a flat spatula to smooth out the sides of the cake. Hold it against the side and rotate the cake to create a clean finish. For a sharp edge on top, run the spatula along the top edge while the cake is on a turntable.
-
Shaping the top edge: If you want a more defined edge, you can use the spatula to press gently against the frosting on the top edge and smooth it out.
