Method
Prepare the pan and coating
- Line a 9x13-inch pan with parchment, leaving overhang on two opposite sides.
- Lightly grease the pan, parchment, and a flexible spatula with the oil.
- Mix the confectioners' sugar and cornstarch in a small bowl, dust the pan with a few tablespoons, and reserve the rest.
Make the marshmallows
- In the bowl of a 6-quart stand mixer, sprinkle the gelatin over 1/2 cup cold water and let it stand for 10 minutes.
- In a 2-quart saucepan, combine the remaining 1/2 cup water, maple syrup, granulated sugar, and salt.
- Stir over medium heat until the sugar dissolves.
- Boil without stirring until the syrup reaches 240°F, about 8–12 minutes.
- With the mixer on low, carefully pour the hot syrup in a thin stream down the inside of the bowl, avoiding the whisk.
- Increase to high and whip for 8–12 minutes, until thick, glossy, and barely warm.
- Beat in the maple extract during the last 30 seconds.
- Scrape the mixture into the prepared pan and smooth the top quickly with the oiled spatula.
Set and cut the marshmallows
- Let the pan stand uncovered at room temperature for at least 6 hours or overnight, until the marshmallow is set and no longer tacky.
- Dust the top with the reserved coating and lift the marshmallow out using the parchment overhang.
- Cut into 1 1/2-inch squares, dusting the knife and tossing the cut sides in coating as needed.
- Store in an airtight container at room temperature for up to 1 week.
Notes
For the best texture, boil the syrup to 240°F and pour it in a thin stream while the mixer is on low. Store airtight at room temperature for up to 1 week; refrigeration is not recommended, and the marshmallows can be frozen airtight for up to 2 months. For a corn-free coating, substitute arrowroot for the cornstarch.
