Is fudge gluten free?

Classic fudge is not gluten free. Because a lot of chocolate and store-bought ingredients are not gluten free, it is very hard to purchase fudge that is celiac friendly at a bakery or store. Our keto fudge recipe is gluten free because we use only four ingredients to make it. Every ingredient is from a source that contains zero gluten. We suggest if you want to make gluten free fudge, you follow a specific gluten free recipe and use gluten free chocolate like ChocZero to ensure there are no grains.


How to make fudge in a microwave?

To make fudge in a microwave, all you have to do is melt butter, heavy cream, and chocolate together. Add the chocolate to a bowl and put it in the microwave on medium heat for 30 seconds. Remove from the microwave and stir gently. Continue stirring in 15-second intervals until fully combined. Be careful not to stir too much: this will ruin the fudge’s consistency and make it grainy.

We prefer to make our keto fudge in the microwave because it doesn’t require a candy thermometer. It also has fewer user errors. When boiling fudge, you have to worry about burning the candy and causing its consistency to change. Watching carefully in the microwave reduces user error.


How do you make Nutella™ fudge?

Nutella™ is a great base for fudge that has rich chocolatey flavor and perfectly soft. To make a hazelnut chocolate fudge, simple combine butter & heavy cream over low heat. Once melted, stir in chocolate chips of your choice. We chose no sugar added white chocolate chips for a balanced flavor. Last, drizzle in a ½ cup of a ½ cup of chocolate hazelnut spread. Place in a lined 8 x 8 pan and cool until set. Since Nutella™ is not keto friendly due to its high sugar content, we have swapped it for ChocZero Hazelnut Spread: a perfect substitute!

How to make peanut butter fudge?

Peanut butter fudge is a classic old-fashioned fudge recipe. To make peanut butter fudge, just add ½ cup of peanut butter to this recipe in place of the ½ cup of hazelnut spread. All you will need is ½ cup of peanut butter, 3 cups of sugar-free chocolate chips, 4 tbsp of butter, and ½ cup of heavy cream. After you microwave the liquid ingredients and chocolate, stir gently, adding the peanut butter in and mix until combined.


Is fudge keto friendly?

Fudge is not keto friendly. Most traditional fudges used sweetened condensed milk which is high in calories and contains a staggering 166g of sugar per cup! Sweetened condensed milk is also high in sodium and high in carbs, making it not only an unhealthy option, but not suitable for those on a keto diet or diabetic. Our keto friendly fudge recipe is made for diabetics and dieters who want to create keto fudge. It specifically is made with low carb ingredients like our sugar free chocolate chips and our sugar free hazelnut spread to keep the carb count low & the flavor profile high!


How to make sugar free fudge?

To make a delicious sugar free fudge recipe, you can use sugar substitutes like Splenda™ or natural ones like monk fruit. Any granular sugar alternative that measures 1:1 with sugar and that can be baked with is best for a rich fudge. We choose to use monk fruit and no sugar alcohols or artificial sweeteners in our fudge recipe and we swapped traditional sweetened condensed milk or evaporated milk for heavy cream to keep this fudge keto friendly.


Does fudge melt?

Since fudge is a cooked candy, it won’t melt unless it’s reheated to over 125 degrees. This means you don’t have to worry about storing your keto fudge in the fridge. Simply store in a room temperature, air tight container for up to 4 weeks! You can also freeze fudge in an airtight container for up to 3 months, making it a perfect dessert to make in large batches.


Why doesn’t fudge harden?

The softness of your keto fudge will depend on 2 things: time and temperature. If you used too much heavy cream, the fudge will be too soft and moist to set. Make sure you’re adding just enough heavy cream to keep the fudge creamy, but not over saturate. Another reason your fudge didn’t harden properly is cooking it too hot. Patience is key with keto fudge and you want a low and slow method. Keep the temperature of the saucepan low, don’t rush with high temps or your homemade fudge won’t set.


Why does my fudge crumble?

Dryness is the main culprit for a fudge that crumbles. Overcooking your fudge will cause a harden & crumbly consistency. On the contrary, if you don’t heat it long enough, your fudge will be too soft. Another common issue is fudge crumbling when you’re cutting it.

Once your fudge is cooled for 2-3 hours, run a sharp knife along the edges of the pan. This will allow you to pull the parchment paper up to lift the fudge onto a cutting board. When cutting keto chocolate fudge, use a sharp chef’s knife and cut in a straight down motion. Don’t see-saw, because it will crumble.

If your fudge starts to crumble when you cut into it, even using a straight-down motion, then it’s likely too cold. Let it sit at room temperature for a while to soften and try again. Another tip to avoid sticking is run the knife under water between cuts, and dry before making each cut!
