I often find myself spending spare time browsing the aisles of Target. It’s a magical place that never bores me no matter how many times I go, and seems to always offer things I never knew I needed. During one of my recent Target trips, I found a little bottle of poppy seeds on clearance. Without a second thought, the poppy seeds were rolling around with the rest of my unnecessary (but totally necessary) things in my basket. And so the brainstorming began of what to do with these little black seeds. Poppy seeds are usually paired with lemon – there are lemon poppy seed muffins, scones, pancakes, etc. All are super tasty, but Mr. Lemon, it’s time for you to share the LIMElight (see what I did there?) with your fellow citrus friends!

These shortbread cookies are lightly sweetened and have a buttery, slightly crumbly and perfectly crispy/crunchy texture. The grapefruit zest adds a wonderfully bright pop of flavor, while the poppy seeds bring that extra textural element. The grapefruit icing is just the right amount of sweetness for these cookies. Overall, this cookie gets an A+.

I followed this recipe by Gimme Some Oven, making just a few minor changes. Let’s make the shortbread cookie first. Put coconut, sugar, grapefruit zest, and vanilla extract in a food processor or blender and pulse a couple times (this mixture smells absolutely fantastic, so take a big whiff of it and savor it). If you’re using a food processor, add flour and pulse; then slowly add butter slices (about 1 tbsp per slice) while pulsing until combined. If you’re like me and don’t own a food processor, put your flour and sugar/coconut mixture in a large bowl and simply cut your butter into your flour (see my Figgy Shortcake post for my thoughts on cutting butter, and instructions on how to do it). Once you reach this point, add the poppy seeds, and knead your dough until it comes together, adding half a teaspoon of water (or grapefruit juice) if needed. Roll it out on a large floured surface into a ¼ inch sheet. Cut out your cookies using whatever cutter you’d like; repeat with excess dough until all your dough is used. I used a 3 inch cutter, and ended up with about 20 cookies. Place cookies on an ungreased cookie sheet. Bake for 15-17 mins at 325F (the bottoms should be just slightly brown). Transfer to wire rack to cool.

Icing time. Simply mix your powdered sugar, grapefruit juice and salt. Add more juice to get a consistency that allows you to decorate appropriately. I made my icing on the thicker side and put it in a ziplock baggy to trace the outlines of the cookies. Then I added a little extra grapefruit juice to make it runnier, and used a spoon to fill in the circles. The thicker icing acts like a little barrier to prevent the runnier icing from spilling over the edges. Decorate with more zest and/or poppy seeds.

And that’s it. Go make yourself a cup of coffee, tea, or whatever you want and enjoy this delicious cookie! Thank you Mr. Lemon for giving up your monopoly on poppy seeds for this killer cookie!
