Prepare two cookie sheets with cooking spray, parchment paper, or silicone mats.
In a stand mixer or with a hand mixer, cream together the shortening, sugar, and eggs.
Add in the mashed bananas, buttermilk, and vanilla. Mix well.
Next, add the flour, baking soda, and salt. Mix until just combined.
Add the mini chocolate chips and mix until evenly distributed.
Add the finely diced strawberries and fold them in very gently. Don't mix too much or cookies will turn pink.
Using a cookie scoop or a spoon, put about 2 tbsp of batter down on a large cookie sheet, making sure to place the batter scoops 2 inches apart. You should be able to fit 12 cookies on one cookie sheet.
Bake at 350 degrees for 10-11 minutes.
Frost while warm, if you want them to be glazed, or wait until they have cooled, if you want them to look like the cookies in my pictures.
TO MAKE THE FROSTING:
Using a hand mixer, cream together the butter, powdered sugar, vanilla, and 2 tbsp of heavy cream. Mix until fluffy, adding up to two more tablespoons of the heavy cream, if needed.
Spread a thin layer of frosting on each cookie and ENJOY!
