Pro Tips for Success
- Cake Batter Consistency. You do not want the cake batter too runny. If it appears too thick, a splash more milk can be added. However, too much liquid can result in a gummy texture.
- Lemon Zest. Only zest the yellow part of the lemon skin and not the white portion or it will add a bitter taste to the cake.
- Blackberry Filling. The consistency should be somewhat similar to a jam and not runny. If it’s too runny, consider adding an additional teaspoon of cornstarch while cooking.
- Allow to cool. Let the cake layers and blackberry filling cool completely before assembling. If not, the frosting may melt.

How to store
This cake is best when eaten fresh. However, you can store the cake in an airtight container in the fridge for up to 4 days wrapped in a light layer of plastic wrap. If you’re not consuming it within a day, it’s recommended to refrigerate to preserve the blackberry filling.
When serving, you can take the cake out an hour or so beforehand to let it come to room temperature, which will improve its texture and flavor.
