Servings & Timing
Yield: 6–8 bars
Prep Time: 10 minutes
Freeze Time: 2–3 hours
Total Time: About 3 hours
Ingredients List
For the Marshmallow Filling
- 1 cup sugar-free marshmallow fluff
- 1 scoop vanilla protein powder
- 2 tablespoons powdered erythritol (or sweetener of choice)
- 1 tablespoon water
- 1 teaspoon vanilla extract
- Pinch of salt
For the Chocolate Coating
- 1 cup sugar-free dark chocolate chips
- 2 tablespoons coconut oil (for smooth texture)
Instructions
Step 1: Prepare the Marshmallow Filling
In a bowl, mix the sugar-free marshmallow fluff, protein powder, powdered erythritol, water, vanilla extract, and a pinch of salt. Stir until smooth.
If the mixture is too thick, you can add a tiny bit more water to get a fluffy texture.
Step 2: Shape the Marshmallow Bars
Line a baking pan with parchment paper. Spoon the marshmallow filling into the pan and spread evenly.
You can use a silicone mold for a perfect bar shape or just cut into bars later.
Place the pan in the freezer for 2–3 hours or until the marshmallow center firms up completely.
Step 3: Prepare the Chocolate Coating
In a microwave-safe bowl, melt the sugar-free dark chocolate chips with coconut oil in 30-second intervals, stirring in between, until smooth and glossy.
Step 4: Coat the Bars
Once the marshmallow center is firm, remove from the freezer and cut into bars.
Dip each bar into the melted chocolate, ensuring it’s fully coated. Let the excess chocolate drip off and place the bars back onto the parchment-lined pan.
Step 5: Freeze Again
Place the bars back in the freezer for 10–15 minutes until the chocolate is firm.
Step 6: Serve
Once the chocolate coating has set, the bars are ready to enjoy! Store them in the refrigerator for up to 1 week or freeze them for up to 2 months.
Additional Notes
- If you prefer a thicker chocolate coating, dip the bars twice.
- Use a sugar-free marshmallow fluff or make your own using sugar-free ingredients for the healthiest option.
- Customize the protein powder flavor — vanilla or chocolate protein powder works well.
