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.

S'mores Cookie: Trial 1

Fabrication of S'mores Cookie Trial 1.

This beings my efforts to recreate the S'mores Cookie
figure 1.

Procedure:
  1. I started with my standard Chocolate Chip Cookie recipe.  This can be found here: Chocolate Chip Cookie
  2. Graham Crackers were placed on the baking sheets
  3. Large spoonful of cookie dough (standard chocolate cookie size portion) was placed upon graham cracker (see figure 3).
  4. Cookies placed in oven under standard Cookie-baking conditions: 350°F
  5. Marshmallows were placed on cookies at set intervals during the baking process (see figure 4)
figure 2.
figure 3.


Results:
  figure 4.
Observations:
  • Larger amounts of cookie dough will need to be applied to achieve the average radius of 4.5 cm and fully cover the graham cracker square.
  • Marshmallows placed on cookies at Time 0 and Time 5 minutes melted off the cookies.
  • Marshmallows placed at Time 12 minutes became gooey, but did not achieve desired toastedness.  This was the group with results closest to our desired objective.
  • Marshmallows placed at the start of cooling did not adequately melt.
  • Control group (standard chocolate chip cookie, no graham cracker or marshmallows) baked normally.


Conclusions:
Next round I will need to use larger portions of cookie dough per cookie.  Adding marshmallows at the beginning and during cooling did not work well.  I observed that adding the marshmallows after 12 minutes, with ~1 minute to go, gave the desired gooeyness, but lacked toastedness.  Employing another technique (quick broil?) will be necessary to achieve toastedness.

Conclusion: close, but no cigar.

S'more Cookie: Reverse Engineering

 Meet the S'mores Cookie from Cookie Connection, a local chain of excellent cookie shops.  

The S'mores cookie is Emily's favorite cookie from Cookie Connection.  For this reason I have decided to reverse engineer this cookie and create my own.

There are three components to the cookie
1. Melted marshmallows on top (see above photo) 
2. Chocolate chip cookie
3. Graham cracker square base (which provides an excellent textural variation to the cookie)
 The graham cracker base

I acquired an official S'mores cookie and began my analysis.  Here are my observations:
  1. Average radius of the cookie was 4.5 cm (to fully cover graham cracker)
  2. Milk chocolate chips instead of semi-sweet chips.
  3. Marshmallows were nicely toasted.  They were on the cookie long enough to make indentations in the cookie as they baked, but were not completely melted.
These are my notes for now.  Next up will be Trial 1 to replicate this S'mores-y goodness.
