I used to love making classic fudge around Christmas, but as I became more health-conscious, I wanted a better version for the holidays. Traditional fudge, while delicious, is loaded with sugar and carbs, which don’t align with my dietary goals. This led me to create a protein-packed, keto-friendly fudge recipe that still captures the rich, creamy texture and decadent flavor I adore, but without the the things I don’t want!

Now, we can all enjoy a festive treat that’s both satisfying and supportive of a low carb lifestyle.

Key Takeaways

  • Keto fudge is simple to make with keto pantry staples like Prime Chocolate Protein Powder (or cocoa powder), unsalted butter, heavy cream, vanilla, and a keto-friendly sweetener like allulose.
  • The preparation process involves three steps: preparing the pan, melting and mixing ingredients, and setting the fudge in the refrigerator for at least 2 hours.
  • You can customize the fudge by adding nuts, seeds, nut butters, or various flavorings like peppermint extract or cinnamon to suit your taste.

🍽 Essential Equipment Needed

  1. Medium Saucepan: Choose a heavy-bottomed saucepan to ensure even heating and prevent the mixture from burning.
  2. Whisk: A good quality whisk helps in blending ingredients smoothly without any lumps.
  3. 8.5 x 4.5-inch Loaf Pan: Opt for a non-stick or glass baking dish. Lining it with parchment paper makes for easy removal and clean-up. A 9 x 5-inch pan will work as well.
  4. Parchment Paper: Essential for lining the baking dish to prevent the fudge from sticking and to easily lift it out once set.
  5. Measuring Cups and Spoons: Accurate measurements are crucial for achieving the perfect texture and taste.
  6. Rubber Spatula: Ideal for scraping down the sides of your saucepan and spreading the fudge evenly in the baking dish.
  7. Refrigerator/Freezer: To chill and set the fudge, ensuring it reaches the perfect firmness before cutting into squares.

Having the right equipment makes the process smooth and helps achieve the best results for your delicious keto protein fudge!

🥘 Ingredients

The process of making an easy keto fudge recipe is surprisingly straightforward, requiring just a few ingredients that are likely already in your pantry. The essentials include:

  • Prime Chocolate Protein Powder (or cocoa powder)
  • Unsalted butter
  • Heavy cream
  • Vanilla extract

These ingredients form the base of your fudge and ensure a rich, creamy, caramely texture that’s perfect for a low carb diet.

Alongside these fundamental ingredients, a keto-friendly sweetener is necessary to substitute for traditional sugar. For this recipe, allulose tends to work the best. However, options like powdered monk fruit sweetener or erythritol can be substituted, as they blend seamlessly into the keto fudge mixture without leaving a gritty texture. Prime Chocolate Protein Powder (or cocoa powder) also plays a crucial role in this recipe, adding the chocolate flavor.

You can also add unsweetened baking chocolate and unsweetened cocoa powder to elevate the richness of the chocolate fudge. Personally, I leave them out to lower the carb count, and the protein fudge has fudgy, almost chocolate caramel texture. Vanilla extract is another key player that enhances the overall flavor profile. Choosing high-quality ingredients paves the way for an optimal fudge experience.

Why Prime Protein Powder Instead of Sugar Free Chocolate Chips?

I prefer using Chocolate Prime Protein Powder instead of sugar-free chocolate chips for my protein keto fudge because it adds a rich, chocolatey flavor while boosting the protein content. This makes the fudge not only delicious but also more nutritious, aligning perfectly with my keto diet goals. Additionally, using protein powder helps keep the fudge low in carbs and free from any unwanted additives that might be present in sugar-free chocolate chips, ensuring a cleaner, healthier treat.

Moving on, let’s jump into the step-by-step guide to crafting this amazing keto treat!

🔪 Instructions: Step-by-Step Guide to Making Keto Chocolate Fudge

Creating keto fudge is a straightforward process that doesn’t require any baking and takes only about 20 minutes to prepare. Let’s break it down into three simple steps: preparing the pan, melting and mixing the ingredients, and setting the fudge in the refrigerator.

Preparing the Pan

First, line an 8.5 X 4.5-inch loaf pan (or 9″ X 5″), or small rectangular glass container, with parchment paper, ensuring the paper drapes over the sides for hassle-free removal later. Lightly oil the parchment paper with coconut or avocado oil to make sure the fudge doesn’t stick to it. This step is vital because it enables you to lift the entire fudge block out of the pan effortlessly!

With your pan ready, you can move on to the melting and mixing of ingredients.

Melting and Mixing

In a medium saucepan, heat 2 cups of heavy cream over medium heat until it starts to simmer. Toss in 1/3 cup of powdered allulose (or powdered sweetener of your choice) and 4 tablespoons of butter, stirring until everything melts and mixes perfectly. Keep simmering until the mixture thickens, or reduces by half, about 15-20 minutes. This becomes a rather delicious sugar free condensed milk.

Remove the saucepan from the heat and stir in 2 teaspoons of vanilla extract. Gradually add 2/3 cup of Equip Prime Protein Powder (or your favorite chocolate protein powder or cocoa powder), stirring until the mixture is smooth and glossy. 

Setting the Keto Chocolate Fudge

Pour the mixture into the prepared loaf pan, spreading it out evenly with a spatula. Spreading it evenly is key for the fudge to set correctly and maintain uniform thickness. Once the mixture is evenly spread, place the pan in the refrigerator.

Refrigerate the fudge for at least 2 hours or until it is solid. Once set, use the overhanging parchment paper to lift the fudge out of the pan. Cut the bar into bite-sized pieces using a sharp knife. Your keto fudge is now ready to enjoy!

Customizing the Best Keto Chocolate Fudge Recipe

A highlight of this keto fudge recipe is its adaptability. You can easily customize it to suit your taste preferences by adding different ingredients or trying new flavor variations.

We’ll delve into a few methods of personalizing your sugar free fudge recipe to make it uniquely tasty.

Adding Nuts or Seeds

Incorporating nuts or seeds into your low carb fudge recipe can enhance its texture and flavor. Chopped nuts like walnuts or pecans are classic additions that pair wonderfully with the rich chocolate. If you’re looking for a nut-free option, consider incorporating pumpkin or sunflower seeds for a delightful crunch.

You can also experiment with different nut butters, such as peanut, almond, or cashew butter, to add a nutty flavor to your fudge. Whether you choose to mix these ingredients into the mixture or sprinkle them on top, they will elevate your keto fudge to a whole new level.

Sweetener Options

Selecting an appropriate sweetener is key to attaining the desired texture and sweetness in your keto fudge. Keto-friendly sweeteners like allulose or if you don’t have it, monk fruit sweetener, powdered erythritol, or Swerve are excellent choices. These sweeteners blend into the fudge, creating a smooth and creamy texture without any grittiness.

Avoid using granulated sweeteners, as they can result in a grainy texture. If you’re unsure about the sweetness level, start by adding a small amount and gradually increase it to taste. This way, you can customize the sweetness of your fudge to suit your preferences.

Flavor Variations

Playing around with various flavors can add an exciting twist to your sugar free fudge. Adding a few drops of peppermint extract can give your fudge a refreshing minty twist, perfect for the holiday season. Alternatively, you can drizzle melted peanut butter or almond butter on top before chilling to create a rich, nutty flavor.

Some ideas for enhancing the flavor of your low carb chocolate fudge include:

  • Sprinkling sea salt flakes on top before refrigerating
  • Adding chopped nuts or seeds for added crunch
  • Swirling in a layer of peanut butter or almond butter
  • Drizzling melted dark chocolate on top
  • Adding a sprinkle of cinnamon or pumpkin spice for a warm, cozy flavor

The possibilities are endless, so don’t be afraid to get creative!

Tips for Perfect Low Carb Chocolate Fudge

Several vital tips must be followed to craft the perfect keto fudge. First, always use full-fat ingredients like heavy cream and unsalted butter, as they provide a rich, creamy texture. Ensuring your fudge mixture is completely smooth before setting it will also give you the best results.

As I mentioned before, adjust the sweetness to your personal preference, but avoid using granulated sweeteners, as they can add a grainy texture to the fudge. I like to keep this fudge in the freezer and get out a piece or two for a snack. You will need to keep it cold for best results.

Storing and Serving Low Carb Chocolate Fudge

Maintaining the freshness and texture of your sugar free fudge requires adequate storage. Always store your fudge in an airtight container in the refrigerator or freezer to keep it fresh for longer.

Store your protein fudge in an airtight container in the refrigerator. It will stay fresh for up to two weeks. For longer storage, you can freeze the fudge for up to three months.

Refrigeration and Freezing

When refrigerating your keto chocolate fudge, separate the layers with parchment paper to prevent them from sticking together. This will make it easier to remove individual pieces when you’re ready to enjoy them. For longer storage, wrap each piece of fudge in parchment paper and place them in an airtight container before freezing.

To defrost frozen fudge, transfer it from the freezer to the refrigerator and let it sit overnight. This gradual defrosting process helps maintain the texture and flavor of the fudge, ensuring it tastes just as good as when it was first made.

Serving Suggestions

When ready to serve,use a sharp knife to carve it into bite-sized pieces, practicing a straight-down slicing motion to prevent crumbling. For an added touch of flavor, drizzle sugar-free peanut butter over the fudge or pair it with low-carb berries like raspberries or strawberries.

For an elegant presentation, sprinkle the top of the fudge with sea salt flakes or chopped nuts before serving. These simple yet effective serving suggestions will make your fudge even more enjoyable and impressive.
