For Rhubarb Season & Beyond

Once the season gets going for those of us in the north, we all scramble for rhubarb recipes, don’t we?

There’s only so much pie we can eat, only so much stewed rhubarb or rhubarb jam we need to preserve.

That’s where this amazing cookie recipe comes in handy. For folks that don’t like to make pie or simply want something different, this comes together quickly and easily. Plus, cookies are always easy to share at parties, potlucks, bake sales, and more.

Don’t forget, rhubarb freezes so easily. Simply put the diced rhubarb into freezer containers in 1 cup portions. Then use those portions to bake cookies later in the year.

Helpful Hints

This is a pretty straightforward recipe, nothing fancy like all the best cookies but there are a couple of things to keep in mind.

Dice the rhubarb stalks into small chunks. Slices, even thin slices, are likely to feel to big in the final cookies. The easiest way to do this is to slice the stalks into long quarters and then chop into small pieces.

I used salted butter in the original recipe, only because that’s generally what I have on hand. If you use unsalted butter add 1/2 teaspoon salt to the dry ingredients.

These are a rich cookie, I highly suggest keeping them small.

Plain or Frosted

These are good cookies when baked and left plain. Really they’re quite perfect, rich, tart, sweet, a bit of crunch and great with coffee or tea.

However, if you’d like to make them a bit fancier or sweeter or more decadent, add the frosting.

The caramel frosting is a wonderful complement but a plain vanilla icing or cream cheese frosting would be great too, go with what you prefer.

Use homemade or store bought caramel sauce to make the frosting in the recipe below.

I love a sandwich cookie, it always feels so special, like two desserts in one. If you do keep the cookies small, these are an ideal cookie with which to make little dessert sandwiches.

A simple smear of frosting across the tops of the cookies works too if you want more cookies from a single batch.

Optional Additions

The cookies are soft and delicious just as the recipe is written but if you’d like to change it up a bit, you certainly can:

Add up to 1 cup chocolate or white chocolate chips for an even bigger treat.

A cup of finely chopped nuts would also be delicious.

Substitute half of the rhubarb for some diced strawberries for the always wonderful strawberry rhubarb combination.

How to Serve

Make some of each type cookie, frosted, plain, sandwiched and serve them as a type of platter at summer parties or potlucks.

These plain cookies would work well as a kind of ice cream sandwich if you wanted to go that route.

A cookie on top of a scoop of ice cream in a bowl is also a very fun summer treat.

Serve any of the cookies simply with favorite summer beverages like iced tea or coffee and of course you can never go wrong with milk and cookies.

How to Store

The plain cookies will keep for up to about 3 days when stored in an airtight container at room temperature.
