Best Blondie Recipe with Toffee

I can’t be trusted around regular blondie bars, but when you add toffee bits? I have to lock them up to keep from eating the whole pan myself. I can’t help it. I LOVE toffee and I love soft brown sugar blondies so I feel like I need to warn you: these blondies are very addictive!

I’ve been known to call these magical bars because there’s just something so wonderful about mixing toffee into blondies. I have been making this recipe for over 10 years and they turn out perfectly every time!

What are Blondies?

Blondies are like brownies except they’re not made with chocolate. Instead they are made with lots of brown sugar which gives them a rich and soft texture that’s dense like a brownie. They’re light in color – hence the name blondies!


Just like brownies you can doctor them up with add ins and this version has bits of toffee stirred into the batter. It gives them these little pockets of crunch which works really well with the soft texture. I like to use Skor bars which are milk chocolate covered toffee. Trust me, toffee just takes them over the top.

I first had these years ago at a function for my daughter’s school. The mom who made them generously shared the recipe and I have since tweaked it and made adjustments. All the experimenting paid off because they are perfection.

Ingredients in Toffee Blondies

  • Brown sugar: This is the key to the recipe, for flavor and softness. 2 cups of brown sugar keep these moist and fudgy!
  • Butter: Make sure to use unsalted softened butter.
  • Baking powder: I use this instead of baking soda. I find it makes them moister and keeps them soft.
  • Skor bars (toffee candy bars), Heath Bars, or toffee bits: As the mix in

How to make Toffee Blondies

  1. Cream the brown sugar and butter together in a large bowl. Add the eggs and vanilla and continue beating until combined.
  2. Add the baking powder, salt, and flour and stir until combined. Stir in the chopped toffee bars until the toffee bits are distributed evenly into the dough. The dough will be sticky.
  3. Press the mixture into a prepared 9×13 pan. Press more chopped toffee into the top of the batter. Bake the bars for 24 to 26 minutes.

Expert Tips

  • Creaming butter and sugar together is an important step because it incorporates air into the batter which gives the blondies a nice texture. One question I get a lot is “how long does it take?” and it’s not long at all – usually you only need to cream them for one to three minutes. I’m a nerd about this stuff so of course I wrote all about it in my how to cream butter and sugar post – you might like to check it out, too!
  • Only use a METAL pan to bake these in. Glass pans can make them brown on top too much while the center doesn’t bake through. Metal pans conduct heat more evenly.
  • The best way to prepare the baking pan is with tinfoil and cooking spray. Lining the baking dish with foil makes it super easy to lift the bars out in one piece before you slice them (make sure they are completely cool!). Spray the foil with cooking spray so they don’t stick. 
  • The batter for these bars will be very sticky. To make it easier spray your hands with cooking spray before you press the dough into the pan. This will keep it from sticking to you!
  • You will know the blondies are done when the center is a little jiggly. You want to take them out at this point because the bars will continue to cook in the pan as they cool. As they cool, they will set and have the best texture. So, be careful to not over bake them – just check on them early.

How long do blondies last?

These bars last up to a week in an airtight container. The brown sugar keeps them soft for days!

Can you freeze toffee blondies?

Freeze these in an airtight container for up to 3 months.

  • Preheat oven to 350°F. Line a 9×13” pan with foil and spray with cooking spray.

  1. Thanks for sharing. Mine are still in the oven but judging but the taste of the spoon…they will be scrumptiously delish!! One note…the recipe calls for 2 cups brown sugar and the videos states 2 1/4 cups. I followed written recipe so we shall see how it turns out!!
