Seriously though, lots of great desserts have been cranking out of the Vintage Kitty test kitchen. This Blueberry Grapefruit Bars recipe has been a labor of love. It took so many tries to get the right consistency, balance of sweet and tart and perfect ratio of crust to filling…I lost count of how many batches were made!
But here it finally is in all of it’s ooey gooey deliciousness! It’s lick your blueberry stained fingers good! Shortbread, freshly squeezed grapefruit juice and the glorious scent of zested citrus! And the blueberries…they bake down into a thick sweet jelly. Mmmm do you see how the blueberries just ooze yumminess?
These might actually be #foodporn because blueberries are thought to be an aphrodisiac due to their heart healthy, antioxidant properties. Studies have shown that blueberries can improve cardiovascular circulation, memory, and fight urinary tract infections! Way to go blueberries!
So let’s put them in dessert to make it healthier, right? LOL!!! Blueberries are divine in these dessert bars but the grapefruit’s acidity keeps the sweetness factor from going into overload.

Those gooey bits of blueberry look soooooo tempting in the filling, which I can’t get over the fact is grapefruit and not lemon (in a good way). Seriously gooey goodness!

Thanks Megan! Lemons are one of my go to ingredients but I’m trying to mix it up a bit and grapefruit just seems like an underutilized citrus…
