How Many Carbs Are In Peanut Butter Fudge?
Made with peanut butter, sugar, butter, and milk, a small square (about 1 oz or 28 g) typically contains 10–15 grams of carbs, mostly from sugar.
If you use natural peanut butter, keto sweeteners (like allulose or monk fruit) and coconut oil or butter a small square (about 1 oz or 28 g) usually contains 1–3 grams of net carbs, depending on the specific ingredients.
Ingredients
Just 4 ingredients make these tasty sweet treats.
- Natural Peanut Butter: Look for unsweetened, creamy peanut butter with no added sugar to keep it keto-friendly. The natural oils add a luscious texture.
- Butter: These provide the fudge with its rich, melt-in-your-mouth consistency while adding healthy fats to support ketosis. Coconut oil can be substituted for a dairy-free fudge.
- Low-Carb Sweetener: Choose a keto-approved sweetener like monk fruit or allulose. We like to use a brown monk fruit sweetener for a touch of extra flavor but feel free to use the sweetener of your choice. Powdered sweetener dissolves easy so can be a great choice.
- Vanilla Extract: A splash of vanilla elevates the flavors and rounds out the taste of the fudge.
- Optional Add-Ins: Add a sprinkle of sea salt, sugar-free chocolate chips, chopped nuts or a drizzle of sugar-free chocolate for an extra twist!

Keto Fudge Recipe Tips
Stick with a brand that lists only peanuts and salt as ingredients. Avoid those with added sugars or oils.
Make it your own! Swirl in some unsweetened cocoa powder for a chocolate-peanut butter combo or sprinkle in crushed nuts for added crunch.
Increase the protein content by adding protein powder to the mixture.
Storage
Store the fudge in an airtight container in the fridge for up to 2 weeks or in the freezer for a longer shelf life. It softens quickly at room temperature, so serve straight from the fridge for the best texture.
