Blackberry lavender cake! .. because summer isn't over yet!
Swap a portion of sugar in your favorite vanilla cake recipe for lavender sugar or, if adding milk, steep in lavender before mixing in (what I did). Also made a lavender simple syrup to brush on each layer.
For the frostings- first made a simple vanilla buttercream and divided in half, adding blackberry jam and cream cheese to a portion of it.
For the middle layer did a swipe of blackberry jam and plain vanilla buttercream. For the cake's outer frosting I used the blackberry-cream cheese- buttercream.
Top with lavender and fresh blackberries.
