If you're not into the pumpkin, here's another idea for dessert. 

Pecan Sandies.  Hey, who doesn't like pecan cookies? This very simple recipe can have your kitchen smelling great a day before the event ( they have to cool for 24 hours).  I got this recipe from IamBaker.com, and it seems pretty simple.

Here it is:

  • 2 cups (256 g) all-purpose flour, sifted
  • 1 tsp baking powder
  • 3/4 tsp salt
  • 1 cup pecans, finely chopped

  3. Add egg and vanilla and beat until completely incorporated, scraping down sides of bowl as necessary.
  4. Add the sifted flour, baking powder, and salt into a bowl and mix until just combined.

  6. Using a cookie scoop that holds 3 tablespoons, scoop dough place on the prepared baking sheet at least 2" apart.
  7. Press a kitchen glass onto a damp paper towel and then dip it into granulated sugar. Press the glass down onto the dough ball until cookies about 1/2 inch thick. Repeat with all cookies.
  8. Bake 9–11 minutes or until tops of cookies change to a dry look and edges are a light golden brown.
  9. Remove from oven and cool completely on wire racks.

A family is always good to have during Thanksgiving. More importantly, though it's always good to wow them with creative desserts.  Hope they enjoy this one.
