Gelatin Mixture
- 1/2 Cup cold Water (for gelatin)
- 3 – 3 1/2 Tablespoons Gelatin (3 for erythritol based sweeteners, 3 1/2 for allulose based sweeteners)
Sweetener Mixture
- 2/3 Cup Water (for the sweetener)
- 2 Cups Swerve, Lakanto, or Trader Joe’s Allulose (granular)
- Pinch Kosher Salt
Flavor
- 1 1/2 Teaspoons Vanilla Extract
- Prep: Prepare an 8×8 inch casserole dish by lining it with parchment paper. Get your electric or stand-up mixer ready since you will need to work efficiently while the marshmallows are hot. Set this aside.
- Combine Gelatin: In a large bowl, add 1/2 cup cold water and sprinkle the gelatin evenly on top. Whisk gently to combine and allow it to bloom by setting aside for 10 minutes.
- Heat Sweetener Mixture: In a medium saucepan, combine 2/3 cup water, the 2 cups of your chosen low-carb sweetener (Swerve, Lakanto, or Trader Joe’s Allulose), and a pinch of kosher salt. Heat over medium-high heat while whisking until the mixture reaches a boil. Continue boiling and whisking for 2 minutes.
- Whisk Together: After the gelatin has bloomed for 10 minutes, start your mixer on low and break up any clumps in the gelatin mixture. With the mixer running on high speed, slowly pour the hot sweetener syrup directly from the saucepan into the gelatin mixture—do this immediately after boiling to keep the mixture hot. Add vanilla extract. Whisk continuously on high for about 12 minutes until the mixture becomes fluffy and nearly doubles in volume. If using a hand mixer, keep moving it around to prevent the marshmallow mixture from setting prematurely.
- Shape and Set: Pour the fluffy marshmallow mixture into the prepared 8×8 dish. Allow it to rest uncovered at room temperature for 6 hours to firm up. Once solid, use a greased sharp knife (rubbed with melted butter) to cut the marshmallows into desired shapes. Store the cut marshmallows in the refrigerator to maintain freshness and enjoy!
Notes
- Note 1: Adjust gelatin quantity based on the sweetener used—3 tablespoons for erythritol-based sweeteners and 3 1/2 tablespoons for allulose-based sweeteners.
- Note 2: An 8×8 inch casserole dish is ideal for shaping the marshmallows evenly.
- Note 3: The 6-hour drying time at room temperature is critical to achieve the perfect texture before cutting.
