One Bowl Homemade Chocolate Chunk and Toffee Chip Brownies

These might be my favorite brownie recipe yet. Thick, chewy and perfectly chocolatey with bits of toffee and chocolate chunks. Not sure it gets much better than that πŸ™‚

I used all of one bowl to prepare these, can you handle how difficult? Haha, seriously, these are so simple it’s silly to not try the deliciousness yourself.


Start with one stick of butter and melt it until nice and hot in the microwave.

Pour in your semi-sweet chocolate chips and give a nice stir. They’ll melt quickly.

See? They all don’t need to be melted, so no worries if you have a few chips partially melted.

Time for the dry ingredients.

Add them right to the bowl.

Some sugar πŸ™‚

A little brown sugar.

Time for a little mix.

Add two whole large eggs plus one extra yolk.

A touch of vegetable oil. Then give a nice stir until thick and well combined.

Here’s the fun part, the chocolate chunks! I keep mine large and in charge, but you can even use chocolate chips and these will be fantastic.

I also added a generous portion of milk chocolate toffee bits. Heath Brand.

Mix, mix, mix.

Transfer to an 8×8 inch baking pan and now it’s time to bake.

Ahhhh, perfect!

I might frame this picture so I can look at it everyday, lol! Yum!

Perfect brownies, according to me πŸ™‚Β  Enjoy!


One Bowl Homemade Chocolate Chunk and Toffee Chip Brownies


  • 1 stick/8 tablespoons unsalted softened butter
  • 1 1/2 cups semi-sweet chocolate chips
  • 1 cup all-purpose Gold Medal Flour
  • 1/4 teaspoon kosher salt
  • 1/2 cup granulated sugar
  • 1/2 cup packed light brown sugar
  • 2 large eggs plus 1 egg yolk
  • 2 tablespoons vegetable oil
  • 2 cups chocolate chunks
  • 8 ounce bag milk chocolate toffee chips


  1. Preheat oven to 350 degrees F. and line an 8×8 inch baking dish with foil that has been sprayed with cooking spray.
  2. Place butter into a large mixing bowl and microwave until melted and hot, about 45 seconds or so. Pour in chocolate chips and stir until mostly melted. It’s ok, if it’s not perfectly smooth. Add flour, salt and sugars. Mix a few times then add egg yolks and oil. Mix until well combined then add chocolate chunks and toffee chips.
  3. Transfer batter to prepared baking dish, spreading evenly. Bake for 35-40 minutes, until cooked through.

Makes 9-12 Servings

    My fave brownie recipe is a one bowl number, too. There’s something huge to be said for not getting out a mixer, dirtying a bunch of dishes and still getting your chocolate fix on. They look great, Jenny!

    This looks delicious. Do you remember what kind of chocolate you used for the chocolate chunks………milk or semisweet and which brand?

      Jenny says:

      Hi Carol,
      I use bloc chocolate usually from Trader Joe’s but any of your favorite chocolate that you can cut into chunks works great πŸ™‚

  18. 18

    To add entire pieces of chocolate is a wonderful idea ! I’m going to try this this week end !!

  19. 19

    Totally making these – so excited I have all the ingredients!

    Loretta E says:

    These contain all of the things that I love in a brownie…absolutely delicious-looking!!

  25. 25

    One-bowl brownies are the best! These in particular look so perfectly dense and chewy. Yummmm. Love the mix-ins too.

  26. 26

    These look as wonderful as you describe them! Those huge chunks of chocolate look so yummy and I love how dense they look! Someone from work requested brownies, so I think I will be making these this week!

    Which Trader Joe chocolate bar is this..? I want to make them exactly like the picture.

  30. 30

    Amazaramadingdong!! I love how your chunks are actually chunks, sometimes chunks have to overrule chips!!

    Lara says:

    I LOVE the one dish part! They look amazing!

    These do look perfect! Fudgey and amazing. Plus toffee, like my favorite thing ever! Can’t wait to try them.

    Kathryn says:

    I’ve just put these into the oven! My poor 8×8 pan looked like it was about to overflow, so I put the batter into a 9×9. They look amazing so far!

    • 34.1
      Kathryn says:

      They came out beautifully! I’ll definitely make this recipe again. They also freeze very well, which is nice, because I certainly don’t need a whole pan of brownies just sitting on the kitchen counter!

  35. 35

    These brownies look so dense and rich! I want to go make a pan right now πŸ™‚

    Lorna says:

    Made this yesterday and the brownie is really moist and yummy! I love toffee chips and use them in cookies all the time, but didn’t like the taste in these brownies. I had to bake for about 45 minutes – they are very thick and dense. Good recipe, but I think I would omit the toffee next time.

    Annette says:

    Well I made this recipe this afternoon, baked it for 40min and it seemed like it was cooked but when I went to slice it after it cooled I found the centre wasn’t cooked through at all. So they’re back in the oven in the hopes they’ll be ready (and okay) for the dinner I’m going to in half an hour!

    • 37.1
      Annette says:

      Baked them another 20 min, then stuck them in the freezer to cool them down. Tried cutting them again (was already late for my dinner at that point) and it was still uncooked in the middle. Now that it’s sat in the fridge for a few hours the outside parts are edible but the middle is still more like a soft sticky fudge. My oven is working fine so I have no idea what went wrong with this.

        Lb says:

        This happened to me too! Only I forgot them in the oven so bottom & sides are burned. πŸ™

    • 37.2

      I’m having the same problem! I’ve tried cooking them longer and letting them set on the counter but they’re still pure goo! πŸ™

    Brooke says:

    I followed the recipe exactly and mine turned out kind of dry. Why would that be? They smelled good, but they are just dry and crumbling. Feeling kind of bummed about it.

    • 46.1

      Is it possible that the chocolate chips weren’t melted enough or had already mostly set up again before you added the flour? If the chips are dry, it removes a lot of the moisture.

  47. 47
    Heidi says:

    This did not turn out for me. 40 minutes was not enough time. I left it in the oven for one hour and it still didn’t look cooked. I let it set overnight and this morning it was dry on the outside and undercooked on the inside. I liked the idea of the chocolate chunks and the toffee but I will not be making this again.

    I tried this recipe today, and it was fantastic! I didn’t have any toffee chips, so I omitted them – and I added a dash of vanilla extract. It was great using just one bowl, and mixing by hand – a lot less cleanup – and the brownies are delicious. Thanks Jenny!

    how do you get such neat, clean slices? My brownies want to tear up a bit when I cut them!

    Laura says:

    These were probably the best brownies I’ve ever had! And the recipe was so simple too! Thanks for sharing!

  57. 57
    Carrie says:

    Disappointingly, these didn’t work for me – I followed the directions exactly. The middle was just too gooey but not in a good way, They were almost oily/greasy? They went uneaten in my house which is unheard of.
    Back to the drawing board for me.

  58. 58

    Wow these look perfect and super fudgy! I always like to try new brownies recipes! I will have to make them πŸ™‚

  59. 59
    Lyss says:

    πŸ™ These sounded so good. Yummy, easy to clean up, and I had all of the supplies. I made them. The batter tasted decent. I baked them for 40 minutes and the top looked done, but it jiggled. I didn’t want to leave them in for too long and have the edges be overdone. The only part that was cooked was the top. It was like warm pudding with chunks. It was disappointing. I usually have such good luck with your recipes, but I will not making this one again. I do highly recommend your Butterfinger Peanut Butter Chocolate Chunk Cookies; they are my favorite cookie, and I bake a lot.

    Wilma says:

    I’m having the same problem as a lot of other people: So far my brownies have been in for 40 minutes and the top is still bubbling and looks oily and runny, and the toothpick test comes out pretty runny.
