Butterscotch Marshmallows Ingredients

For the Marshmallow Base

  • Cold Water – Base liquid for blooming gelatin; you can substitute half with rum for a boozy treat.
  • Powdered Gelatin – Provides the essential structure for achieving that fluffy marshmallow texture.
  • White Sugar – Main sweetener that balances flavors and guarantees the right consistency.
  • Dark Brown Sugar – Adds depth and a rich sweetness; avoid using only brown sugar as it can change the texture.
  • Corn Syrup – Prevents crystallization; while it can be omitted, it’s recommended for the smoothest results.
  • Salt – Enhances all the sweet notes and balances the overall flavor profile.
  • Vanilla Extract – Infuses aromatic goodness; feel free to adjust the amount to suit your taste.
  • Aged Rum – Optional ingredient that adds a fun, boozy twist to the marshmallows for adult enjoyment.
  • Unsalted Butter – Introduces richness and flavor; ensure it’s melted and lukewarm for easy incorporation.

For Dusting and Coating

  • Confectionery Sugar & Cornstarch – Combines to dust the marshmallows, preventing stickiness and enhancing presentation.
  • Melted Chocolate – An optional coating that enhances flavor and adds a delightful crunch when finished.

How to Make Butterscotch Marshmallows

  1. Bloom Gelatin: Sprinkle powdered gelatin over cold water and let it sit undisturbed for 10 minutes. This step is crucial for achieving that fluffy texture we all love in marshmallows.

  2. Prepare Sugar Syrup: In a saucepan, combine white sugar, dark brown sugar, corn syrup, and water. Stir gently until dissolved, ensuring it blends smoothly without any lumps.

  3. Heat Syrup: On medium heat, bring the mixture to a boil, then cover and allow it to simmer. This step is important to dissolve all the sugar; aim for the syrup to reach a temperature between 242°F and 245°F.

  4. Combine Syrup and Gelatin: Carefully pour the hot syrup into the bloomed gelatin while mixing on low speed. Once combined, increase the speed to medium-high and whip until the mixture becomes light, fluffy, and doubled in volume.

  5. Add Flavorings: Gently fold in the vanilla extract and aged rum, if using, until fully incorporated. This will infuse the marshmallows with that delicious butterscotch flavor.

  6. Fold in Butter: Take about one cup of the marshmallow mixture and blend in the lukewarm melted butter slowly. Once combined, fold this back into the remaining marshmallow base ensuring no air is deflated.

  7. Pour into Pan: Scrape the sticky mixture into a buttered or lined 8 x 8-inch pan, spreading it evenly with a spatula to create a smooth surface.

  8. Set Marshmallows: Dust the top with a mixture of confectionery sugar and cornstarch to prevent sticking. Allow the marshmallows to set for at least 6 hours or overnight, then cut them into squares and enjoy!

Optional: For an added touch, drizzle with melted chocolate for a sweet crunch.

Tips for the Best Butterscotch Marshmallows

  • Temperature Matters: Ensure your syrup reaches 242°F to 245°F for perfect texture. Too low, and they won’t set properly; too high can cause crystallization.
  • Gelatin Blooming: Let your gelatin bloom fully in cold water. This is crucial for achieving that soft, airy marshmallow consistency we all crave.
  • Butter Temperature: Use lukewarm melted butter for easy incorporation. Cold butter can deflate your marshmallows, affecting texture.
  • Humidity Check: Make these marshmallows on a dry day or in air conditioning; high humidity can prevent them from setting properly.
  • Dusting Technique: Generously coat your cutting board or knife with confectionary sugar and cornstarch to avoid stickiness during cutting.
  • Flavor Variations: Get creative! Try adding different flavor extracts or using flavored sugars for unique butterscotch marshmallows.

Make Ahead Options

These Butterscotch Marshmallows are perfect for meal prep enthusiasts! You can bloom the gelatin and prepare the sugar syrup up to 24 hours in advance, ensuring a smoother process on the day you want to enjoy them. To do this, simply prepare the gelatin mixture and store it in the refrigerator, covered, until you’re ready to incorporate it with the syrup. When you’re set to finish the Butterscotch Marshmallows, heat the syrup and combine it with the bloomed gelatin, then proceed as directed. Remember, to maintain that fluffy texture, whip it well and let it set overnight for the best results. Enjoy these delightful treats without the last-minute rush!

Butterscotch Marshmallows Variations

Feel free to make these marshmallows your own with a few simple twists that enhance their deliciousness and creativity.

  • Non-Alcoholic: Omit the rum and add an extra splash of vanilla extract for a delightful family-friendly treat.

  • Flavor Twist: Swap aged rum for flavored extracts such as hazelnut or coffee. This will introduce new and exciting layers to the marshmallow experience!

  • Sugar Options: Use only light brown sugar for a milder flavor or coconut sugar for a hint of caramel undertones. Each option brings its unique taste to the mix!

  • Texture Variations: Dust with crushed nuts or cookie crumbs instead of confectionery sugar for a delightful crunch that enhances the marshmallow’s softness.

  • Heat it Up: Incorporate a dash of cayenne pepper or cinnamon into the mix for a surprising kick that pairs beautifully with the sweetness of butterscotch.

  • Choco Delight: Drizzle melted dark or white chocolate over the finished marshmallows for a rich, sweet coating that adds depth and a new flavor dimension.

  • Seasonal Infusion: Add pumpkin pie spice or peppermint extract (for winter) to keep your marshmallows looking and tasting festive throughout the year!

  • Alternative Dusting: Experiment with cocoa powder or finely shredded coconut as a dusting for visual flair and unique taste profiles that will impress your guests!

Butterscotch Marshmallows (Buttered Rum Marshmallows) Recipe FAQs

What type of cold water should I use for blooming gelatin?
You can use regular tap water for blooming gelatin. I recommend using filtered water if you want to keep the flavors as pure as possible. This step is vital for the marshmallows to achieve that delightful fluffy texture we all adore.

How should I store my Butterscotch Marshmallows?
Store your butterscotch marshmallows in an airtight container at room temperature for up to 2 weeks. If you want to keep them for longer, you can refrigerate them, where they’ll last for up to 3 weeks. Just ensure they are sealed properly to keep that soft, chewy texture intact!

Can I freeze Butterscotch Marshmallows, and how?
Absolutely! To freeze your butterscotch marshmallows, first, place them in a single layer on a baking sheet to prevent sticking, then freeze for about 1 hour. Once firm, transfer them to an airtight container or freezer bag, separating layers with parchment paper if desired. They’ll stay fresh for up to 3 months! When you’re ready to enjoy, simply let them thaw at room temperature.

What do I do if my marshmallow mixture doesn’t get fluffy?
If your marshmallow mixture isn’t becoming fluffy, it could be due to insufficient syrup temperature. Ensure your syrup reaches 242°F to 245°F. Additionally, make sure you’re mixing at the right speed. Start low to avoid splashing, then whip on medium-high until the volume doubles. If it’s still not working, allowing it to sit for a few minutes before mixing again can help.

Are these marshmallows safe for pets?
While marshmallows are generally safe for pets in small amounts, they contain high sugar levels and may cause tummy upsets. It’s best to keep these butterscotch marshmallows out of their reach, especially since they contain ingredients like sugar and butter that could lead to undesirable side effects.

Can I modify the ingredients for allergies?
Certainly! To make the recipe gluten-free, ensure your corn syrup is certified gluten-free. For dairy-free options, try using coconut oil in place of butter. If you’re concerned about allergies, always check the labels of the ingredients you’re using and consider substituting items accordingly.
