As a die-hard peanut butter fan, I’m surprised it has taken so long for me to share a keto version of my fudge cups until now.
This homemade healthy keto peanut butter fudge is easy, portable, and needs no refrigeration. It is exactly like eating a giant spoonful of peanut butter, but better.
When you think of ‘healthy, low-carb, and sugar-free’ fudge, it would be easy to assume that it might sound too good to be true. I promise you this is NOT the case.
Texture wise, this fudge is smooth, creamy, and melts in your mouth. However, it uses good-for-you ingredients. Unlike traditional fudge, this keto fudge uses no condensed milk, no sugar, and no dairy. The taste is incredible- smooth, creamy and melts in your mouth.
Snack, dessert, afternoon treat, or that little something to satisfy your sweet tooth- This fudge is your answer. It may be small in size, but it is deceptively satisfying and you’ll be fine to stop at just one. You’ll love that this fudge is also vegan and gluten free!
How to make low carb peanut butter fudge
- Peanut Butter– You should use a sugar free peanut butter and one that is smooth and drippy in texture. The market is filled with many kinds of no sugar peanut butter, so you should have plenty of options.
- Coconut oil– Refined coconut oil will leave you with no coconut flavor.
- Sugar free sweetener– You can use either liquid stevia drops or some monk fruit sweetener or erythritol. I prefer the liquid stevia, as it maintains a smooth and creamy texture.
- Sugar Free chocolate– Optional, but if you’d like this to be a chocolate peanut butter fudge! Either sugar free chocolate chips or a chocolate bar can be melted over the tops.
Start by preparing a mini muffin pan (18 count) or a silicone pan. Then, place the peanut butter and coconut oil in either a microwave safe bowl or saucepan. Heat the peanut butter and coconut oil mixture until warm. Once warm, whisk together until combined. Add your sweetener of choice, and mix well. Distribute amongst the muffin tin or pan and place in the freezer, to firm up. If desired, melt the chocolate over the tops of each one.
- For some added texture, feel free to use a chunky or crunchy style of peanut butter. Again, be sure it is sugar free.
- If you have peanut allergies, nut allergies, or those who follow a strict paleo diet, I’d suggest using sunflower seed butter or soy nut butter. These both have the most similar texture to peanut butter.
- The sweetener is a little open-ended because you can adjust it depending on your taste buds. Just be wary of what kind you use. Liquid stevia only requires a few drops, whereas a granulated sweetener (like monk fruit), would use 1-2 tablespoons.
- If you aren’t strictly Keto, sugar-free or low carb, feel free to use maple syrup, agave, or even honey.
Storing and Freezing Peanut Butter Fudge
- To store: Sugar free peanut butter fudge should always be stored in the fridge, to ensure it keeps its shape. Keep it in a sealable container, for up to 2 months.
- To freeze: You can freeze keto peanut butter fudge. Place in a freezer friendly container and keep frozen for up to 6 months.
