- 1 1/2 tablespoons unsweetened cocoa powder

How to Make Peanut Butter Chocolate Freezer Fudge
- Line a mini muffin pan with 16 mini muffin liners.
- Add the peanut butter and solid coconut oil to a microwave-safe bowl. Microwave for approximately 1 minute, or until melted.
- Stir the peanut butter and coconut oil together until the mixture is smooth and completely combined.
- Add the maple syrup, vanilla extract, and a pinch of salt. Stir well.
- Divide half of the peanut butter mixture evenly among the 16 lined mini muffin cups. Each cup should be approximately one-quarter full.
- Add the cocoa powder to the remaining peanut butter mixture and stir until smooth.
- Spoon the chocolate peanut butter mixture evenly over the plain peanut butter layer in each muffin cup.
- Place the muffin pan in the freezer for at least 1 hour, or until the fudge is completely firm.
- Transfer the frozen fudge pieces to a freezer-safe container and keep frozen until ready to enjoy.
Make It Even Lower in Carbs
For an extra-low-carb freezer fudge, replace the maple syrup with liquid stevia or another low carb liquid sweetener.
Because the sweetness of liquid stevia varies considerably by brand, begin with a few drops and taste the mixture before adding more. Follow the conversion instructions on your sweetener’s packaging for the best results.
Be sure to use peanut butter without added sugar if you want to keep the total carbohydrate count as low as possible.
Recipe Variations
All Peanut Butter Freezer Fudge
For an all-peanut-butter version, leave out the cocoa powder. Divide the peanut butter mixture evenly among the muffin cups and freeze as directed.
All Chocolate Peanut Butter Fudge
To make every bite chocolatey, stir the cocoa powder into the entire peanut butter mixture before pouring it into the muffin cups.
Large Freezer Fudge Cups
Use a regular muffin pan to make eight larger pieces instead of 16 mini pieces. Keep in mind that each large piece equals approximately two mini servings, so you’ll need to double the nutrition information if you track your food.
Freezer Fudge Squares
Don’t have a mini muffin pan? Line a loaf pan with parchment paper, leaving enough parchment hanging over the sides to lift out the fudge.
Pour the peanut butter mixture into the pan, add the chocolate layer, and freeze for approximately 2 hours. Once firm, lift the fudge out of the pan and cut it into squares.
Tips for the Best Freezer Fudge
- Use creamy peanut butter for the smoothest consistency.
- Stir the mixture thoroughly so the melted coconut oil is completely incorporated.
- Choose unsweetened cocoa powder to avoid adding unnecessary sugar.
- Taste the mixture before freezing and adjust the sweetness if necessary.
- Keep the fudge frozen because coconut oil softens quickly at room temperature.
- Check every ingredient label if you need the recipe to be strictly gluten free.

How to Store Freezer Fudge
Store peanut butter chocolate freezer fudge in an airtight, freezer-safe container. Place parchment paper between the layers to prevent the pieces from sticking together.
For the best texture, enjoy the fudge directly from the freezer or let it sit at room temperature for 1 to 2 minutes before eating. Don’t leave it out for too long because the coconut oil will begin to soften.
Frequently Asked Questions
Is freezer fudge gluten free?
Yes, the ingredients in this freezer fudge are naturally gluten free. However, always check the labels on your peanut butter, vanilla extract, cocoa powder, and other ingredients if you are sensitive to gluten or cross-contact.
Is this freezer fudge keto?
The maple syrup version may not fit a strict keto diet. To make it more keto-friendly, use unsweetened peanut butter and replace the maple syrup with liquid stevia or your preferred keto-friendly sweetener.
Can I use natural peanut butter?
Yes, but natural peanut butter can separate. Stir it thoroughly before measuring so the oil is evenly incorporated. The texture may be slightly softer depending on the brand you use.
Can I keep freezer fudge in the refrigerator?
This fudge is best stored in the freezer. It may become too soft in the refrigerator, especially if your kitchen or refrigerator runs warm.
Can I use a different nut butter?
Yes! Almond butter, cashew butter, or sunflower seed butter can be substituted. The consistency and flavor may vary slightly depending on the type and brand you choose.
