Candy Bar Blondies

Around the holidays, there is an influx of sweet treats to our house. On Halloween, depending on the weather, we could have 60-100 trick or treaters. I like to buy full-size candy bars, but having 40 left over makes for a big dilemma. Thank goodness I have an easy solution.

Make a batch of blondies and load them up with your favorite candies! Voila, Candy Bar Blondies! I’ve taken my favorite blondies recipe and stirred in some frozen chocolate candy bar chunks along with M&M’s. My girlfriends were dying for the recipe when I shared these. They would not lead you astray.

What to Do with Halloween Candy Leftovers

Unsure of what to do with the leftover Halloween candy? Sampling a few of your favorites is always required, but there’s only so much your pants will stretch! Not like these treats are particularly kind to your waistline, but consider the mixing, spreading, and cutting to be a form of exercise. A batch of blondies is the perfect solution!

Tips for Making Blondies

Blondies are baked in a square or rectangular baking pan just like brownies, but without any cocoa or chocolate which give brownies their distinctive look and flavor. The name came about because blondies resemble brownies in shape when cut but are flavored with vanilla instead of chocolate. They are also called a blonde brownie. It’s interesting to note that blondie recipes appeared in cookbooks before brownie recipes.

Here are some tips for making blondies:

  • Use either light brown sugar or dark brown sugar when making blondies. I’ve made this recipe with both, but prefer dark brown sugar as it gives a richer, more caramel like flavor and extra moisture.
  • Melting the butter makes it easier to mix the dough, plus gives a chewy texture.
  • This basic recipe can be tweaked with different add ins. Add 1 1/2 cups of your favorites, like white or dark chocolate chips or even a combo, nuts, coconut, toffee bits, or all M & M’s.
  • Do not use a mixer to combine the ingredients. Using a mixer will over activate the gluten and make your blondies less tender and will also add air into the batter.
  • PRO-Tip: Slightly under baking will make your blondies moist and chewy. 
  • PRO-Tip: Reserve some M & M’s and chocolate chips to carefully press onto the surface of the blondies when they come out of the oven. This will give a more finished, bakery like appearance!

Prep Time 20 minutes
Cook Time 30 minutes
Total Time 50 minutes

Ingredients

  • 1 1/2 cups flour
  • 1 teaspoon baking powder
  • 1/4 teaspoon salt
  • 12 tablespoons butter (1 1/2 sticks), melted and cooled
  • 1 1/2 cups light or dark brown sugar
  • 2 eggs, lightly beaten
  • 4 teaspoons vanilla extract
  • 1-1 1/2 cups chocolate based candy bars, chopped (Milky Way, Reese's, 3 Musketeers, Hershey Bars, M&M's, etc.)*See Notes
  • 2 tablespoons chocolate chips and M&M's to garnish, optional

Instructions

  1. Preheat oven to 350ยฐ. Line a 9 x 9-inch baking pan with nonstick foil, leaving enough overhang to help you lift the blondies from the pan when they're done.Set aside.
  2. Whisk flour, baking powder, and salt together in medium bowl; set aside. Whisk melted butter and brown sugar together in medium bowl until combined. Add eggs and vanilla and mix well.
  3. Using a rubber spatula, fold dry ingredients into egg mixture until just combined; do not over-mix.
  4. Fold in candy bar pieces and pat batter into prepared pan, smoothing top with an offset spatula. Push in a few chocolate chips on top of dough to garnish, if desired.
  5. Bake until top is shiny, cracked, and light golden brown, 27-30 minutes; do not over-bake. Immediately after removing from the oven, push in a few more chocolate chips and/or M&M's on top of dough to garnish, if desired.
  6. Cool on a wire rack to room temperature. Remove bars from pan using foil and cut to serve.

Notes

Chop candy bars with caramel or nougat and freeze while preparing the batter and preheating the oven to prevent any over-melting.
