Springtime Rhubarb Bar Cookies

Devon 1 Comment

Bright, flavorful with a sweet-tart palate pleasing thing going on, these easy rhubarb bar cookies are a welcoming springtime treat!

It is March now and a very mild winter in the Pacific Northwest has rendered the valley that I call home alive with blooming flowers and the first of the spring grass (as is important to us farmer types).  The ground is still yet too damp to work up and frost comes too often to consider planting the garden.  But I yearn for the textures, flavor and aromas of full blown spring.  Rhubarb is that perfect, refreshing bright beacon of the spring to come.  So for the Nitty Gritty Man’s birthday, I was inclined to produce something to celebrate his special day and the coming season.  These easy-peasy rhubarb bar cookies, topped with just a little vanilla bean ice cream were the perfect indulgence for a weekday celebration.

I am going to let you in on a little secret – the rhubarb season is not yet in full swing here in Oregon as of the date I composed this post.  Pssst, I had some pre-sliced and frozen in the freezer.  There are moments in my life when I just adore “past me” – like when a major step in the prepping process is already done.  So while I await the fresh stuff for jams and pies, this little rhubarb cookie doesn’t even suggest that its star ingredient spent a lengthy hibernation in my freezer.
