What is The Best Food Coloring To Use For Keto Fudge Recipe 

You might find that reaching for a natural food coloring is a better fit for you. I know many on keto are trying to make the best choices for their bodies, and natural is always great. The only thing with natural colors is you won’t get as vibrant of colors. But, to be honest it is still gorgeous fudge.

What Confectioner Sweetener Do You Use For Low Carb Fudge 

I reached for Swerve. If you have another keto friendly sweetener just read the conversion of how much to add to the recipe. I like the smoothness of the Swerve it really adds great flavor to the fudge.

Best Way To Store Patriotic Keto Vanilla Fudge Recipe 

You will want to store any fudge you don’t plan to eat right away in the fridge. I find that you can either place in an airtight container and place in the fridge or wrap in aluminum foil then place in the fridge.

Either method seems to work, and if you prefer room temperature fudge then just allow it to sit out on the counter for a bit before eating.

Can You Freeze Fudge 

Yes. I slice my fudge into bite-size pieces and then wrap in aluminum foil. Then place in a freezer sealable bag or airtight container. You can store your fudge in the freezer for up to three months. When ready to eat it, simply place in fridge the night before or place on the counter for a quicker thaw.

Can I Use Different Colors Of Food Coloring In Fudge 

Absolutely. Or if you want to leave the food coloring out for a vanilla fudge. I added coloring to fit the 4th of July, but that doesn’t mean you have to. I have made this with red and green for Christmas, pastel colors for Spring and Easter, and so on. This recipe is incredibly versatile so don’t box it into just summer.

How to Make Keto Fudge Recipe 

Start by grabbing a pot and heating your whipping cream and butter in a saucepan. Once the butter melts you want to whisk in 1/3 of Swerve confectioner sugar and mix until it is fully combined. Then grab your vanilla and whisk it in. Now you want to cook your fudge down so it begins to thicken.

Once it is thickened, pour most of the mixture into a parchment lined loaf pan. Leave some back to make the red and blue colored fudge. I just held back around 1/4 cup total to split for the colors.

Take the remaining fudge and put into two separate bowls. Add in food coloring into each, making one red and the other blue. Then add the mixture over the white fudge. Drizzle it all around, and then take a knife and give it a swirl effect. Freeze until hardened then slice and serve.

How Long Do You Have to Freeze Fudge To Harden 

You will want to freeze this fudge for around 3 hours. If you don’t it will be very mushy and not hold together like traditional fudge.

Yes. You are welcome to make a larger batch of fudge to fit your needs. I have made a double and even triple batch around the holidays and had no issues with it.
