Step By Step Instructions
Great for beginner bakers, peanut butter fudge requires just a couple of easy steps - melt, mix, and chill!
Note: Scroll to the recipe card at the bottom for the ingredients quantities and full detailed method!
Step 1 - Heat The Peanut Butter
Firstly, grease and line a 20cm square baking tin with baking paper.
Place the butter and peanut butter in a large microwave safe bowl, and heat on high for one minute in the microwave.
Stir, then heat for a further minute on high.
If using a Thermomix: Place the butter and peanut butter into the Thermomix bowl and melt for 3 minutes, 80 degrees, Speed 2 (or until melted).
Step 2 - Add The Icing Sugar
Once the peanut butter and butter have melted, add the icing sugar mixture to the bowl.
If using a Thermomix: Add the icing sugar mixture and mix for 10 seconds, Speed 4. Scrape down the sides of the bowl and mix for a further 10 seconds or until combined and smooth.
Stir until all ingredients are combined.
Step 3 - Chill
Spread the fudge mixture into your prepared tin, press down firmly and smooth the top.
Place in the fridge for up to 2 hours, or at least 30 minutes, before cutting into squares.
Expert Tips
You really can't go wrong with this easy fudge!
- I use a good quality store-bought smooth peanut butter for the creamiest consistency.
- You could substitute peanut butter for cashew butter if you prefer.
- If the mixture is too thick when your icing sugar has been added, just add a touch of milk and mix this through.
- Line your baking tin with baking paper to allow for easy removal once the fudge has been chilled and is ready to be cut into pieces.
- Chill for a minimum of 30 minutes (if you can't wait any longer!) or up to 2 hours to firm up well.
- Use a sharp knife to cut the fudge into squares once it has chilled. See my instructions on cutting the perfect slice for tips on presentation.
- Store microwave peanut butter fudge for up to a week in an airtight container at room temperature, or for 2-3 weeks in the fridge.
- Freezing - wrap fudge well in clear wrap or foil and place in an airtight container for up to 3 months. Allow to defrost in the fridge before consuming.
FAQs
A little salt always helps to bring out the flavour in both sweet and savoury dishes, but as the peanut butter already has salt added, I recommend using unsalted butter for this microwave peanut butter fudge. However, if salted butter is all you have, use that, as the difference is slight.
I do recommend lining your tin with baking paper, as this makes it a lot easier to remove microwave peanut butter fudge from the tin - and makes cleaning up easier too!
Remove the fudge from the fridge 20 minutes before cutting. Use a hot and dry knife (dip the knife in hot water and then dry completely) to score the fudge. Once the fudge has been scored, press down firmly with the knife to slice all the way through. See my instructions on cutting the perfect slice for additional tips on presentation.

The best peanut butter fudge I have ever made! It is so good, sweet and if you heat it up a bit, it melts so smoothly in your mouth. I don't even like peanut butter stuff, but this is an exception, I loved this and so did my family!
