I have not had great success with making fudge, but that is all about to change with this little recipe! Delicious Caramel & White Chococlate Microwave Fudge.
Posted July 4, 2018, Updated December 1, 2025

Over the years I have tried and failed to make fudge but I am determined to get the knack. But I am starting with the easy recipes first. I have often mentioned over on my Facebook page my inability to make fudge and people have kindly shared their no fail recipes with me which I have stored away for testing.

This recipe was given to be many years ago and it is so simple I had to start with this one. It is just 4 ingredients so how can I fail! Best of all for me is that it is made in the microwave and done in under 15 minutes! If you have a no fail fudge recipe then be sure to share it in the comments below.
UPDATE: I have found the original poster of this recipe for Caramel & White Chocolate Microwave Fudge, so a huge thank you to Marie from It’s Marie Made, you can find the original recipe and instructions here

I have often wondered if my lack of fudge skills come from the fact we use gas for cooking hence the simmering stage a little tricky to manage, or if I am impatient (yes) or lacking in the heavy bottomed pans (no probs with a heavy bottom here…..). Either way it hasn’t been top of my skill set.

This recipe makes a huge batch of fudge so is perfect for a school bake sale, as Christmas gifts or just to take as a plate somewhere special.
There are a few tips I can recommend for baking fudge in the microwave, first of all is that you want to ensure that the sugar does not burn, in order to do this I reduced the power of my microwave as it is a 1600W, so I set the cook time to 10 minutes and reduced the power to 50%, stirring every 2-3 minutes until the fine sugar crystals were completely dissolved.
You may need to cook longer to get the sugar to dissolve depending on your microwave.

The other top tip is when you use the chocolate ensure it is either melts or your favourite white chocolate bar, something that will MELT. Don’t do what I did the first time and use the drops which are specifically marketed to hold their shape!! It all worked out in the end but another sort of chocolate would have been ideal.
Final note, this is cooked at a high heat and it gets SUPER hot and I would love for everyone to take care when handling the mixture, the bowl and all things related to it so have a towel on hand.

LOVE this FUDGE. It’s the one our teenage son knows to make for our birthdays, fathers day, mothers day etc. It does make a lot so he often halves it, but the important thing is to remember to adjust the cooking time! Just made it now for grandmother’s day tomorrow & I sprinkled sea salt on top to make it more salted caramel. Yum thanks Anna!
justamumnz says
Brilliant to know!
Patty says
I’ve made it with the same amount of dark chocolate at least 70% and it’s wonderful
Maggie says
Just came across this recipe while looking for something to use Caramilk Chocolate in. Have you thought about investing in a Thermomix? You could then convert your recipes – the secret is to grate the chocolate first, or chop it in a food processor as fine as you can get, before melting.
Colleen Silvester says
Made this and will be making it again.
Simple recipe and was not only easy to make but tastes divine.
Thanks!
justamumnz says
So glad you liked it.
Anna says
Hi, wondering if this would work with milk chocolate? Thanks
justamumnz says
I’ve not tried, the cocoa solids are a little different. But if you do please let me know how it goes.
Karen Funk says
Thank you! that helps a lot. I will double check on Google to see how they convert these ingredients. Can’t wait to try this.
Karen Funk says
This sounds delicious and something to make even in the summer since the microwave won’t heat up the kitchen. I would like to know how to translate grams into cups/tablespoons, etc. such as 175 grams of butter is equal to ? in cups and 375 grams of white chocolate equals ? cup(s). Thanks for your help. Also, when you refer to a tin of sweetened condensed milk would that be a 14 ounce can for me?
justamumnz says
It depends on the country you are from, in the US cups are 240ml in NZ, where I am, they are 250ml. You can try to convert this on google for best results, specify the cup measurement you are hoping for. 3 NZ Cups of Brown Sugar is 600 grams, and a tin of condensed milk is 395 grams or 14 ounces. ☺️
Shobana says
Sounds fab…will definitely give this a go!
Quick question…how many grams is 1 tin of condensed milk?
Thanks
Shobana
justamumnz says
397 grams

I think I made something similar with craisins and pistachios in it. It was yummy and I ate most of it. Too scared to make it again!
