blue raspberry cake recipe

As a kid, I proclaimed blue raspberry to be my favorite-flavored anything. Something about blue raspberries was just so much better and cooler than regular old raspberries.

Blue Raspberry Cupcakes

I stockpiled Blue Raspberry Frooties that were tossed at local parades, I begged my mom to buy me Blue Raspberry Icees from the machines in the Target food court, and the first-ever Warhead I dared to punish my taste buds with was, of course, the blue raspberry kind.

Remember Warheads? Those babies were not for the faint of heart. It took a special kind of person (read: naive middle-schooler, AKA me) to let one of those grimace-inducing sour candies into her mouth and keep it there until it dissolved completely.

I totally managed that feat circa 1998 (after about seven failed attempts). Impressive, I know. 😉

Back in the day, I honestly believed that “blue raspberry” was different from and far superior to “raspberry.”

In my defense, look at that pretty color! Definitely more attention-grabbing than plain white or raspberry-tinged pink frosting.

Blue Raspberry Cupcakes

This cupcake originated a few months ago when I helped host a baby shower for my cousin and her cute new baby boy. I wanted to create a dessert that was blue, a play on the guest of honor’s last name, and an acknowledgment of her love of berries and fruit in general. These unique cupcakes fit the bill for all three! We called them “Blue Ras-Baby Cupcakes.”

I struggled over how to include a “blue raspberry”  (or any raspberry) flavor without using some store-bought, artificial-tasting mix. Do I bite the bullet and add Jell-O to some Betty Crocker batter? Use fresh red raspberries, pretend they’re blue, and settle for a tougher, denser cake? I didn’t exactly have access to real blue raspberries (Yes, they do exist!) – but then, they don’t quite look like the vibrant childhood flavor I was going for.

In the end, I decided that nothing about blue raspberry was all that natural, anyway. I made my favorite vanilla cupcakes (adapted from the best cookbook ever) the old-fashioned way, but then I incorporated the blue raspberry flavor in just the frosting. I loved it! The cupcakes didn’t taste like they came from a box (because they didn’t!), and the frosting was sweet and full of raspberry tang, with just a little zing to them.

The secret blue raspberry ingredient? Kool-Aid!

I didn’t have any trouble finding it at my local grocery store, it only cost a couple of cents, and it provided the perfect blue raspberry flavor that I’d been hoping to find.

Topped with a fresh raspberry, these cupcakes were pretty perfect! They were a hit with all the guests, including one uninvited one…
