Blackberry Lemon Cake! This beautiful layer cake is made with lemon chiffon cake, blackberry buttercream studded with fresh berries and zesty lemon curd.
My recipes are often inspired by seasonal ingredients, especially fruits.
You can get decent blackberries any time of year, but summer is the time for the freshest berries. I love baking with blackberries because they have a deep, full flavor and of course that gorgeous color.
Blackberries, like pretty much all berries and fruits, pair wonderfully with lemon. The tang of lemon enhances the berries natural sweet/tart flavor.

- The Limoncello syrup can be made up to a week ahead and refrigerated.
- The blackberry puree be made ahead and refrigerated for 1-2 days or frozen for up to 3 months.
- The cake layers can be made ahead and stored at room temperature for 1 day or frozen for up to 3 months.
- The Swiss Meringue Buttercream can be refrigerated for 2-3 days or frozen for up to a month. Bring the buttercream back to room temperature and re-whip before using.
- The assembled cake should be refrigerated until 1-2 hours before serving, or as long as 4-5 hours ahead if the room is not very warm. You want the buttercream to soften before serving for the best flavor.

Puree the other half of the berries in a food processor. Strain the puree through a fine sieve to remove the seeds. You should have about 1 cup of puree.18 oz blackberries
