FAQs
How can I make the frosting less sweet?
You can reduce the amount of powdered sugar and balance it with more butter or a touch of heavy cream.
Can I make this cake ahead of time?
Yes, you can bake the cake layers in advance and freeze them. Just wrap them tightly in plastic wrap and foil before freezing. Thaw them before frosting.
How do I prevent my cake from sinking in the middle?
Ensure you don’t overmix the batter and that your oven is fully preheated before baking. If your cake is sinking after baking, it could be due to underbaking, so try adjusting the baking time.
Can I freeze the finished cake?
Yes, you can freeze the fully assembled cake, but it is best to freeze it without the ganache. Wrap it tightly in plastic wrap and foil.
How do I get a smooth buttercream frosting?
Beat the buttercream on high speed for several minutes to get it fluffy and smooth. You can also sift the powdered sugar before adding it to avoid any lumps.
Can I use a stand mixer to make the frosting?
Yes, using a stand mixer can help achieve a fluffier, smoother buttercream, especially if you’re making a large batch.
What’s the best way to frost the cake?
Use an offset spatula for smooth, even layers of frosting. For a more textured look, you can use a piping bag to create swirls or rosettes.
Can I make this recipe gluten-free?
You can substitute the all-purpose flour with a gluten-free flour blend. However, results may vary, so make sure to check for the proper texture and moisture level.
