Twix Bar Brownies

I’m quite fond of baking with candy bars. I’ve puKit Kat’s in Lemon BarsHeath Bars in CheesecakesSnicker’s Bars in TartsButterfingers in Blondies & Pie & Cookies, and Milky Ways in Brownies, too. It was time to experiment with Twix. I took my all-time-favorite brownie recipe, and added Twix Bars to make Twix Bar Brownies.

Adding candy bars to desserts is basically a great idea!  I don’t know about you, but I always feel guilty about buying a candy bar at the store to just eat and enjoy.  But if I buy them to add to desserts I’m making at home, somehow I can justify that as being okay!

✏️How to make Twix Bar Brownies:

*The complete, printable recipe with all ingredients and instructions is at the end of this post.

  1. Preheat the oven to 350°F. Butter and flour a 12×18×1-inch (half-sheet) pan. Line with foil or parchment that hangs over the sides for ease in getting them out (butter the foil/parchment).
  2. In a heatproof, medium-bowl set over a saucepan of simmering water, heat the butter, and chocolates until melted and smooth; cool slightly.
  3. In a large bowl, whisk together the eggs, espresso powder, vanilla and sugar. Stir the egg mixture into the slightly cooled chocolate mixture. Cool to room temperature.
  4. In a medium bowl, sift together the flour, baking powder and salt; add to the batter. Stir 12 ounces of chopped Twix bars into the chocolate mixture. Then pour the batter into the prepared baking pan and smooth the top with a rubber spatula. Place slices of the full-size Twix Bar onto the top of the brownie batter.
  5. Bake for 25 to 35 minutes, or until a toothpick inserted into the center comes out clean with a few crumbs attached; do not overbake! Let cool completely before cutting.  My best tip is to cover the brownies tightly and chill overnight. Chilled brownies are easier to cut.

➡️Recipe Tips:

  • These taste even better the second day.
  • If it’s a warm day inside your house, you might consider chilling the Twix bars before you try to cut them.
  • I like to just barely slice off the edges all around the entire brownie after taking it out of the pan. Then, I slice it into bars. To me they just look a little cleaner that way. (Don’t worry, we still gobble up those edges!)

✔️What to do with Twix Bar Brownies:

  • This recipe makes a lot, so it’s perfect to have on hand for a large gathering.
  • Need something to contribute to a bake sale? Make at batch and put a couple brownies in individual baggies. I guarantee your contribution will sell out first!
  • Keep some in the freezer for days when a special after school snack is needed. A glass of cold milk can round out this surprise treat.

★How to Store:

These brownies can be stored in a tightly sealed container, either refrigerated or not, for 2 to 3 days. They also freeze beautifully for 2 to 3 months.

❤️Why I love this recipe:

  1. As I mentioned earlier, I enjoy baking with candy and I love how the combination of a fudgy brownie and Twix bars came together. I think they are pretty addicting!
  2. These are always a hit with both family and guests. Kids, especially, think I’ve created a little magic when I pull these brownies out. They’re always the first dessert to disappear.
  3. I love that this recipe makes a lot of brownies. It gives me so many options for how and when to serve them.

    Are these moist brownies or dry brownies

    1. Lori Lange says:

      Moist!

  2. Hannah says:

    Ohh! I can’t wait to make these! I was wondering what a 12x18x1 inch is? Is it a regular cookie sheet or a larger one and if I don’t have one, what would be another good pan to make them in? Also, would these bo good to ship and if so, what would be a good way to protect them to make sure they get there safely?

    1. Lori Lange says:

      Hi Hannah, It’s best if you can use the large rimmed baking sheet mentioned. If not, the batter is too much for a 13×9. You could always make them in a couple of different pans if you had to. I think they’d be good for shipping. Just wrap them well, and then put them in a sealed container of some sort.

  3. Robin Deal says:

    Can these be made without the espresso powder?

    1. Lori Lange says:

      The purpose of the espresso powder is to intensify the flavor of the chocolate. Yes, you can leave it out… but it just won’t be as rich of a flavor.

  4. Yana says:

    Hi, when do you add in the chocolate chips?

    1. Lori Lange says:

      The chocolate chips are melted with the other chocolate.
