This Seaside Cake transports you to crisp clear waters and breezy salty air! The enlivening flavors of lemon and blueberry are paired with a blueberry filling. Coated with a graham cracker buttercream complete the ultimate beach dessert!
Lemon and blueberry evoke summer months; humid with heat and heavy with harvested berries. This Seaside Cake was inspired more by the concept of the sea, rather than the seasonality of it’s ingredients. The sharp blue tones of this cake mirror those B-roll travel posters of Greece. Hilly crescent shaped bays, vividly speckled with blue roofed white houses.
Can flavors arouse feelings? I’m certain of the latter correlation. Fresh levity and biting saltiness evoke seaside settings. Here the saltiness is not a dehydrating salt bomb. Rather, the salt from the graham cracker buttercream delivers a sophisticated level of salt, balancing the sweetness from the blueberry swirl and blueberry buttercream.
I need to mention and reiterate the crazy amazing flavors of this Graham Cracker Buttercream. Pureeing the Graham crackers with heavy cream smooth the texture without compromising the taste. Essentially the frosting tastes like the crust of a cheesecake. Buttery and with that killer twin combo of salty and sweet. There is no getting sick or bored of this flavor!
Smooth and slick, the Seaside Cake embodies Bobby Darin’s version of Beyond the Sea. This Seaside Cake encapsulates that picturesque experience you never had with childhood beach vacations. Children crammed in the back of a car, impatience mounting. Folding chairs blocking the rear windshield. The packed bloated car, barreling down narrow state and county roads.
A true seaside drive vacation—bought to you by we’re not going to Disney World and foreign countries are dangerous. It is the vacation instigated by a father still adamant about QUALITY TIME. And it’s a quality time that is not quelled with technology. The vacation is the experience of being together. Together and flustered. Kids amuse themselves by counting telephone poles and hitting their sibling to break up the icy silence between both parents. Mom read the map wrong, and dad is gripping the steering wheel to prevent a a spousal misdemeanor.
Okay I digress with a tangential fake situation, but the cake conjures up so many different scenarios!
