Mystery Cookies

As I have stated before, I like reading Joanne Fluke’s Hannah Swensen mystery series.  The books are fun and easy to read.  The added bonus is the author provides recipes.  I have found the recipes for watermelon cookies and pretzel chocolate chip cookies in her book.  This is another one of her recipes found in the Lemon Meringue Murder.

I made these cookies once and I remembered people raved about their taste.  They couldn’t believe the secret ingredient in these cookies.  I do not know where I put my copy of the Lemon Meringue Murder so I lost the recipe.  This week I decided to google the recipe and got lucky.

These cookies are addictive!  I don’t know how many cookies I ate after I baked two cookie sheets worth.  (The rest of the dough is in the fridge waiting to be baked.)
