Combine flour, powdered sugar and butter in the bowl of your food processor and pulse until the mixture becomes crumbs. (You can also use a bowl and cut the butter in with a pastry cutter or with the back of a fork).

Add in lime juice, zest, and cornstarch. Pulse until combined. Add in cranberries and pulse a couple times to mix them in.

Turn mixture out onto a pastry board, or parchment paper. Knead the dough with your hands until combined.

Form dough into two balls, wrap and allow them to chill for 30 minutes or up to 2 days.

When ready to bake, preheat oven to 325 degrees.

Line a baking sheet(s) with parchment paper.

Work the dough until its malleable and can be formed and rolled out to about ¼ inch thick. Cut into rounds, rectangles or whatever shape you like. You can also free form into individual bars. You can also roll into a log/cylinder shape and slice into ¼ inch thick rounds.

Place onto parchment paper lined baking sheet and bake for 12-15 minutes or until set.

You don't want these to brown.

Allow cookies to cool on baking sheet for a couple minutes, then carefully move them to a cooling rack to cool completely.

When ready to ice the cookies, combine powdered sugar and lime juice in a small bowl. Make sure mixture is on the thicker side and coats your spoon, dripping of slower vs super runny. I like to ice these in my cold garage. You can ice in small batches, using a small spoon to drizzle and the back of the spoon to spread. Quickly, zest a lime to get zest falling onto freshly iced cookies and place a few pieces of chopped cranberries on each cookie as well. Repeat with another batch until all are finished. Allow them to set in your cold garage or fridge. Once set, store in a tin, box or cookie jar.
