I have been making homemade marshmallows for many, many years now, but I somehow never manage to post some of the more fun varieties.  This is SUCH a fun and easy one to make.  A huge hit with everyone who was lucky enough to eat one (or two, or three).  Enjoy!

Homemade S'mores Marshmallows!

Butter a 9x13 glass pan OR butter two 8x8 pans.  Sprinkle the bottom of the pan(s) with a layer of: 

GF graham crackers, crushed

Just one of the 8 x 8 pans buttered and lined with crushed GF graham crackers

Combine in a mixer with whisk attachment:

½ cup cool water

3 pkg. (1/4 oz each) (This is about 2 1/2 Tbsp or 7 1/2 tsp) unflavored gelatin

 

In a small, deep saucepan, combine the following over medium heat.  Make sure the liquid fills no more than 1/2 of your pan because it will bubble up while heating. Cook, stirring regularly, until syrup reaches 240 F on a candy thermometer:

½ cup cool water

1 ½ cups sugar

1 cup light corn syrup

1/8 tsp. salt

 

I find heating to 240F takes ~20-30 minutes, and will go in phases of seeming not to increase in temperature to suddenly jump up 5-10 degrees.  So, make sure you’re paying attention, particularly at the end.

Remove your hot sugar from heat.  With the mixer on low speed, slowly pour the sugar syrup into the softened gelatin.  Increase speed to high and whip until closer to room temperature, about 8-10 minutes. After a few minutes, it will start looking like marshmallow!  
 
Towards the end add and beat in:
1 tsp vanilla bean paste OR vanilla extract

Gently fold in - some will melt and swirl, but enough should remain un-melted so you have a nice blend in your marshmallows:

1/2 - 1 cup mini semi-sweet chocolate chips

Spread gently on top of your crushed graham cracker in your prepared pan.  Use slightly dampened hands (wet them again as needed) to spread your marshmallow evenly.   Sprinkle the top of the marshmallows with additional crushed GF graham crackers.  

Pressed in the pan, smoothed, and ready for topping. 

Topped with crushed graham cracker, and left to dry for a few hours.  Yum!

Let your marshmallows sit at room temperature for 3 - 4 hours to dry.  Slice, using a well buttered knife, buttering again as needed.  Roll your freshly sliced marshmallows in more crushed GF graham crackers.  Store extras in an air-tight container.  They will retain their freshness for 1 - 2 weeks (I couldn't tell you if they last longer because they've never made it past two weeks).  Enjoy!
