S'mores Cookie: Trial 2

Fabrication of S'mores Cookie Trial 2.
figure 1.

Procedure:
The same procedure from Trial 1 was followed with these alterations:
  1. the amount of cookie dough used was 2 or 3 times larger (small handful) than a normal chocolate chip cookies.  See figure 1. above, note cookie dough size in relation to the graham cracker squares.
  2. Removed both baking sheets at 13 minutes and applied marshmallows to Tray 1.
  3. Total bake time was 15 minutes
Results:
figure 2. (above) Tray 1 
 figure 3. (above) Tray 2 

 Observations:

  • Larger cookie size melted over the graham cracker perfectly.
  • Marshmallows added at 13 minutes melted slightly as desired
  • Marshmallows added at the start of cooling did not observably melt.
  • Control group (seen top-left of figure 2.) was a good indicator of when cookies were done
  • larger cookie size only made 24 cookies.

Conclusions:
The unmet goals from Trial 1. were cookie size and toasting the marshmallows.  This trial achieved perfection on cookie size.  New techniques were not employed for toasting marshmallows and so those results are the same as Trial 1.  Total bake-time of 15 minutes and adding marshmallows at 13 minutes was well timed and should be repeated.  Taking the baking sheets out of the oven to apply marshmallows allowed for better deployment (rather than reaching inside a 350 oven).
Summary:

  • Use larger cookie dough portions, approximately a small handful, which should yield 24 cookies per batch.
  • Remove trays and add marshmallows at 13 minutes.
  • Bake for a total of 15 minutes.

While the quest may continue to one day perfect toasting the marshmallows on top, for now this working recipe is go for further enjoyment.
