5-Ingredient Peanut Butter Fudge | Ambitious Kitchen (2024)

A few weeks ago I posted these epic, peanut butter oatmeal cookie bars and AK readers went NUTS for them. For good reason! So hello, I took that decadent peanut butter chocolate combo for today’s dessert and bring you: no bake peanut butter fudge with peanut butter cups in every bite.

Yes, I put actual peanut butter cups into this melt-in-your-mouth freezer fudge.

This easy dessert has just 5 ingredients and will be one you make again and again. It’s inspired by my famous tahini cookie dough fudge AKA one of the most popular desserts on AK ever. After seeing you all make the tahini fudge over the years I knew I had to put a peanut butter twist on it.

You should probably make a triple batch, store it in your freezer right this second and enjoy this peanut butter magic for days.

Simple ingredients for the best peanut butter fudge

That’s right, this low carb peanut butter fudge recipe has just 5 ingredients and requires zero cooking. There’s no powder sugar involved, just a bit of pure maple syrup to sweeten! Here’s what you’ll need to make it:

  • Peanut butter: use a natural, creamy peanut butter to give the fudge and nice consistency. I love Wild Friends peanut butter — use the code AMBITIOUS15 to get 15% off!
  • Coconut oil: some melted coconut oil will help the fudge to firm up in the freezer.
  • Maple syrup: sweeten the fudge with a little pure maple syrup.
  • Vanilla: I recommend using a good quality vanilla extract because the flavor will really shine through.
  • Peanut butter cups: can we talk about the big chunks of PB cups in every bite? Truly MAGICAL. Feel free to use good old Reese’s cups (the mini ones are the best!) or use a brand like Justin’s to keep the fudge dairy free and vegan.
  • Sea salt: this is of course optional, but a sprinkle of some fancy sea salt on top makes the peanut butter fudge extra special.

Optional ingredient swaps

Out of any of the 5 ingredients? Here’s what I can recommend substituting in this peanut butter cup fudge:

  • For the peanut butter: any nut butter will work in this freezer fudge, but I recommend sticking with peanut butter for that amazing flavor. Plus, the peanut butter cups are just too good to resist!
  • For the coconut oil: melted butter will also work in place of the coconut oil.
  • For the peanut butter cups: if you don’t have any peanut butter cups feel free to use mini chocolate chips, a chopped-up chocolate bar, or simply drizzle the peanut butter fudge with some melted chocolate before freezing.

Can I use a different sweetener?

I think that honey, brown rice syrup and date syrup would likely work just fine, but I recommend sticking with maple syrup to get the best flavor.

Homemade peanut butter fudge in 5 steps

  1. Prep your pan. Line an 8×4 inch loaf pan with parchment paper.
  2. Mix the fudge ingredients. Add all of your ingredients besides the peanut butter cups and sea salt to a bowl and mix it up until smooth and creamy.
  3. First freeze. You’ll then pour the peanut butter fudge into your loaf pan, tap the pan on the counter to smooth it out, and freeze it for 10 minutes so it hardens up just a little bit.
  4. Add the peanut butter cups. After your fudge has firmed up a little, sprinkle on the chopped peanut butter cups so they nestle into the top. You may need to press them down just a tiny bit.
  5. Freeze again & enjoy. Place the fudge back in the freezer for 30 minutes to an hour until it’s firm enough to cut. Then, cut it into 15 pieces and enjoy!

FAQs

Why won t my peanut butter fudge harden? ›

The main reason is that your Fudge has not reached the optimum temperature. If your mixture only reaches 110 or 112 degrees Celsius it will always be soft. That's why we recommend investing in a sugar thermometer. Another reason your Fudge is not setting is that the ratio of liquid to sugar is too high.

Why is my peanut butter fudge dry and crumbly? ›

Too little time and the water won't evaporate, causing the fudge to be soft. Conversely, cook it too long and fudge won't contain enough water, making it hard with a dry, crumbly texture. Pay attention to the timetable specified in the recipe, and you'll get the hang of it after a batch or two.

Why won't my condensed milk fudge set? ›

The most common culprit behind unset fudge is inaccurate temperature control. If the sugar mixture hasn't reached the correct temperature, your fudge won't set. Ensure you use a reliable candy thermometer and follow temperature guidelines meticulously to achieve the desired consistency.

How to make fudge thicker? ›

How can you fix soft fudge? Put it in a microwave safe bowl that is large enough that it won't boil over. Reheat it to the boiling point and cook for about 3 more minutes. Then you can beat some powdered sugar into it if this doesn't make it set.

How to fix fudge that didn't set? ›

To fix it, you can reheat the fudge mixture over low heat and continue cooking until it reaches the proper temperature. Be sure to use a candy thermometer to monitor the temperature accurately. Alternatively, you can try to salvage chewy fudge by mixing it into ice cream or using it as a topping for desserts.

Why is my fudge not setting enough? ›

If the fudge is very soft and slightly chewy then it is possible that it did not quite cook to soft ball stage and next time the mixture should be cooked to a slightly higher temperature (soft ball is 112-116c/235-240F and a sugar or candy thermometer can help).

What makes fudge firmer? ›

Cooking is necessary to dissolve sugar crystals and to evaporate part of the water in the cream. The length of this step has a direct impact on the firmness of the fudge.

How do you make fudge more solid? ›

How do you fix fudge that is too soft? Bring the fudge back to a boil with 1–2 US tbsp (15–30 ml) of cream. If your fudge is soft or runny, it probably didn't come up to a high enough temperature while it was cooking. Put it back into the saucepan and add 1–2 US tbsp (15–30 ml) of 35% fat whipping cream.

How do you make homemade fudge firmer? ›

​Harden the fudge:​ Place your container or tins in the fridge for 2 hours, which is the time it takes for the fudge to set. Once it's hardened, cut the fudge into 12 pieces or remove it from the muffin tins. Store in the fridge or the freezer (if you don't devour it right away).

What to do with failed fudge? ›

My advice to you is to just pour it in a jar, call it something else delicious, and pretend you meant for it to be that way. The nice thing about my “failed” fudge is that it tastes absolutely delicious! A spoonful of the delectable treat will make you want for more.

Do you stir fudge when it's boiling? ›

Know When and When NOT to Stir

Stir the ingredients to dissolve the sugar until the mixture comes to a boil. If your recipe uses milk, stirring will keep the mixture from curdling. But once it reaches about 236–238 degrees F/113–114 degrees C (the "soft-ball" stage), do not stir it or even shake the pan.

What happens if you boil fudge too long? ›

Too cooked

The result is hard and brittle fudge. To save the fudge, put it in a saucepan with 45 to 60 ml (3 or 4 tbsp.) of 35% cream and bring to a boil, stirring until the sugar is completely melted. Then let it boil without stirring until the thermometer reaches 114 to 115 °C (237 to 239 °F).

How to fix peanut butter fudge that is too soft? ›

How do you fix fudge that is too soft? Bring the fudge back to a boil with 1–2 US tbsp (15–30 ml) of cream. If your fudge is soft or runny, it probably didn't come up to a high enough temperature while it was cooking. Put it back into the saucepan and add 1–2 US tbsp (15–30 ml) of 35% fat whipping cream.

Why is my peanut butter fudge still soft? ›

If there is too much evaporation, when the cooking time is too long, there will not be enough water left in the fudge and it will be too hard. Conversely, if the cooking time is too brief and there is not enough evaporation, too much water will remain and the fudge will be too soft.

How do you fix fudge that is too dry? ›

Fixing Fudge

  2. Stir the fudge over low heat until it dissolves. ...
