The title of these bars is in no way adequate for the amazingness that they are – I couldn’t convey that in a title that was short and sweet, and the word “gooey” got that message across in the best way. But they’re more than gooey. So much more.

These are rich, caramelly bars that are chock full of toffee bits and chocolate chunks and then to top it all off – literally – I poured an ENTIRE CAN of sweetened condensed milk on top, just to see what would happen.

Wanna guess what happened?

The sweetened condensed milk caramelized, turning almost into my so-loved dulce de leche, but still maintaining a little gooey, drippy milky goodness. The milk layer on top adds an extra dimension of sweetness and richness that I’ve truly never really found in another dessert I’ve made.

I might start pouring sweetened condensed milk on everything I make, cause so far it’s never been a bad addition.

Mmm, that stuff is pure heaven.

I know these bars sort of look like brownies (and not the prettiest brownies at that), but that is simply due to the lovely dark color created by the dark brown sugar and the massive chocolate chunks. These are chewy, toffee blondies of the best sort.

Seriously. You gotta try these. Thank me later.

Gooey Toffee Blondies
Prep time
Cook time
Total time
Serves: 16
  • 1 cup (2 sticks) unsalted butter, melted
  • 1½ cups dark brown sugar, packed
  • 2 large eggs
  • 1 tablespoon vanilla extract
  • 2 cups all-purpose flour
  • ¼ teaspoon kosher salt
  • ⅔ cup toffee bits (I used Heath)
  • 1 cup semi-sweet chocolate chips
  • 1 (14 oz.) can sweetened condensed milk
  1. Preheat oven to 350F. Line an 9-by-13-inch pan with aluminum foil or parchment paper and spray with cooking spray; set aside.
  2. In a large mixing bowl, combine the melted butter, brown sugar, eggs, and vanilla, and whisk to combine. Add the flour, salt, and stir until just combined, taking care not to over-mix. Fold in the toffee bits and chocolate chips. Pour batter into prepared pan, smoothing it lightly with a spatula or offset knife.
  3. Pour the can of sweetened condensed milk evenly over the top of the batter.
  4. Bake for 18 to 23 minutes. The edges will be browned and slightly pulling away from sides of pan. The sweetened condensed milk should be bubbling and turning light brown. Allow bars to cool for at least 2 hours before slicing and serving into 16 squares. I like to refrigerate them before cutting to make them easier to cut. Bars can be stored in an airtight container at room temperature or in the refrigerator for up to 1 week, or in the freezer for up to 3 months.

  12. Christine says:

    Making these right now! Can’t wait to see how they turn out :p

    • Christine says:

      I put them in for the full time and they’re still runny…

      • Hi Christine, I’m sorry they stayed runny! Every oven temperature runs different so yours probably just needed a few extra minutes to allow the sweetened condensed milk to caramelize and thicken more.

  13. These look amazing, Rachel! So gooey, gorgeous and perfect for indulging in something deliciously sweet! Lovely recipe.

  14. WHAT?!? I literally just gasped out loud when I pulled up your page [my fiance is giving me really odd looks…].

    I don’t even know what to say here, and I am never at a loss for words, other than bravo! I am going to hustle into the kitchen and poke through my cupboards. I KNOW I have a can of sweetened condensed milk in there…I just must!

  15. Goodness, you’ve done it again. That first photo is just pure perfection. An entire can of sweetened condensed milk over the tops of brownies? Utterly genius, my friend. :)

  16. dinner belle says:

    These looked fabulous, so I just made them. The condensed milk did’t caramelize like I’d hoped before I was scared the brownie part would be overdone, so I popped the pan under the broiler for a minute to get the c.m. bubbly and browned – will let you know how it worked. Thanks for the recipe!

  17. These seriously look amazing! I love caramel and the way you describe the sweetened condensed milk baking into these is killing me! Pinned!

  18. Want to try these but can’t get the recipe to open.

  19. Can’t get the recipe to open. Can someone help?

  20. These look so sweet and decadant!
