Inspiration: I wish I could say that I made these cookies for someone’s B’day, but alas, it’s the recipe’s use of sprinkles that drew me to this particular cookie. These tiny flecks of color always make me happy when I get to sprinkle them into one of my bakes. 

Despite my passion for sprinkles of any variety, if this were back in March, I would’ve shied away from baking them. However, since reading Kate Lebo’s series of arguments in The Book of Difficult Fruit, I am far less trepidatious about using imitation or cheap(er) almond extract in my bakes. Which is a wonderful thing, since almond extract is one of the key tastes in the quintessential birthday cake flavor. (BTW: If you haven’t read The Book of Difficult Fruit, I highly recommend you give it a try. Click here for my full review.) 

The magazine where I found this recipe.

With imitation almond extract in hand, I set about whipping up these festive treats….Only to realize I didn’t own vanilla bean paste or all-natural jimmies, the recipe writers recommended using. The latter I already knew I was missing. However, on my birthday, my husband gifted me a three-pound container of jimmies to play with in my bakes — and they are definitely not all natural. Though it went against the recipe’s recommendation, I went with what I already had on hand. 

The vanilla bean paste was more troubling. 

However, by the time I read the recipe’s fine print, I was already neck-deep in multitasking, and pausing my cookery to run to the grocery store for a single ingredient wasn’t a viable option….So I improvised. Using two teaspoons of vanilla powder and the innards of one vanilla bean in an attempt to recreate the clean taste of the missing paste. Which worked surprisingly well!

The other alteration I made to these bespeckled treats was reducing their size. Rather than portioning off the dough in half-cup scoops, I used my standard tablespoon-and-a-half scooper — then adjusted the cooking time for the smaller cookies. (For me, large cookies are great as a special, sometimes treat you buy at a bakery. But for the everyday cookie? Smaller is definitely better, as they are far easier to dunk in a cup of coffee.) 

Cookie dough!

However, what I enjoy about these large cookie recipes is that if you do decide to reduce their size, they typically yield about two dozen cookies rather than the standard thirty-six to forty-eight.

Even with these minor adjustments, the cookies turned out great! Soft and cake-like, they went down a treat with my husband’s co-workers.

Agatha Christie’s Canon of Characters: I definitely think Miss Marple would make these Birthday Cake Cookies. They are simple to whip up, easier to transport than cupcakes, and still make the recipient feel special.

Of course, the byproduct of this gesture isn’t anything to sneeze at either. 

Taking the time to bake something especially for them, plus the sheer act of recalling their birthday in time to act on it, could potentially lead the recipient to reveal a piece of crucial information they might not have otherwise divulged to Miss Marple during an investigation. 

Though I don’t see this beloved elderly spinster as being this Machiavellian, I don’t think she would turn away from using every advantage she could — if someone was in imminent danger. And since St. Mary Mead’s an invention from the mind of Agatha Christie, imminent danger could be very deadly indeed.
