Making homemade toffee can be harder than it looks. I’ll show you every toffee fail you can possibly have and how to fix them all. Then, I’ll share my homemade toffee recipe for chocolate-covered toffee with pistachios. This post is for you for all the times you made toffee from scratch and failed. I tried to make homemade toffee, and I messed up everything possible.

It took three tries…two of which ended up in the trash. I am sharing everything I learned, and a video that shows some of my “bloopers” and tough lessons. If you love chocolate desserts as much as I do, you will want to check out my best gluten free chocolate desserts.

How to Make Homemade Toffee:

Today, we are going to talk about homemade toffee. I love the stuff but had never thought to make it from scratch. I wanted to give it a try, and I found a great toffee recipe here. The recipe by FunkySeaMonkey looked easy enough.

I was naive to think this pistachio toffee candy would be easy to make…I could almost taste the buttery crunch of the toffee! I had great plans to use this toffee as a topping for a dessert I created…not to mention my kids wanted to make teacher gifts with it.

A pot of cooking toffee where the butter separated out. It looks oily.

FAIL #1:

Butter separating out

Here was my first attempt at making this homemade toffee recipe. I had two cups of sugar and two cups of butter. I didn’t realize how important temperature could be. See that buttery oil slick on top of my toffee?

My first batch of toffee started great…I had a pot of boiling toffee. It was browning beautifully. Then, butter happened.

Spreading toffee out on parchment paper after the butter separated out.

The butter separated from the toffee, leaving a big oil slick-looking goo.

You can see it when I dumped the toffee onto the parchment paper. Nothing is more frustrating than when the butter separates from the sugar in cooking toffee!

Common toffee making mistakes:

Here are the mistakes I made on the first batch of homemade toffee:

I started with way too high of a heat. (At least, I think this was an issue.) I set my portable cooktop at 260 degrees F.
I stirred too quickly. I didn’t realize this could be an issue.
I didn’t add a dash of salt. They say you can save a ruined batch of toffee by adding a dash of salt. It didn’t work for me with this batch, but I added a little salt in my second attempt.

To combat these issues, I tossed this batch of greasy, buttery toffee into the trash and started again.

Second attempt at making toffee:

The butter and sugar melting in a sauce pan.

This time, I started with a lower heat starting temperature on my cooking surface. I gradually melted the sugar and butter and heated up my toffee.

A whisk drizzling some hot toffee back into a sauce pan.

Things are thickening up nicely, and the butter is still behaving!

Toffee Making Tips:

I used the whisk, mixing slowly. I think this allowed the sugar to blend into the butter as the toffee mixture heated up.

What color does toffee become when cooking?

The homemade toffee is ready. See the beautiful golden brown color? And the butter stayed mixed in with the sugar. (YAY!)

How to prevent toffee from separating:

To prevent separation this time, I gradually used a whisk to mix the toffee ingredients. (I tried not to stir too often, but when I did, I used the whisk.)
I slowly cooked my toffee mixture to the perfect 300º F. I started my cooktop at 160º F and gradually increased the temperature to 212º F.
My toffee browned beautifully, and I poured it onto the pan.

So far, everything was perfect. The butter didn’t separate, and the toffee looked creamy and delicious—time to add the melted chocolate and pistachios.

The chocolate spread perfectly onto the chocolate. You can see how quickly the pistachio toffee hardens. See the underside? I put the tray in the freezer to cool for a few minutes.

I removed the tray and broke apart the toffee.

And here we have FAIL #2.

The chocolate didn’t stick to the toffee. So now I had a thin chocolate layer broken into bits and a separate toffee layer all broken into bits. Ugh, this is not looking good for chocolate-covered toffee!

I went to Google again to see what could have caused the chocolate not to stick to the toffee.

Why chocolate didn’t stick to toffee:

This likely happened because the toffee started to cool before I added the melted chocolate.
Some recommend putting the chocolate bits on top of the toffee and letting the heat melt the chocolate.
Another recommendation was to dust cocoa powder on top of the toffee just before adding the melted chocolate.

By this point, I was a little over all of my failures!

I did what any person tired of tossing food into the trash would do. I microwaved the chocolate back on! (I didn’t have the heart to toss another batch of pistachio toffee in the trash!)

Here is a video I put together to show you my whole process for making this homemade toffee recipe. I didn’t include the video of the buttery disaster of the first batch, but you can see that in the pictures above!
