How to Make Candy Bar Blondies
Making Candy Bar Blondies is simple, and you don’t need any special skills. Follow the steps below, and you’ll have a delicious treat in no time.
Ingredients:
- 1 cup (125g) all-purpose flour (spooned & leveled)
- 1/2 teaspoon baking powder
- 1/8 teaspoon baking soda
- 1/4 teaspoon salt
- 1 cup (200g) packed light brown sugar
- 1/3 cup (5 Tbsp; 70g) unsalted butter, melted
- 1 Tablespoon pure vanilla extract
- 1 large egg
- 1 and 1/2 cups chopped chocolate candy bars (I used Milky Way Midnight, Twix, Snickers, and Butterfinger)
Directions:
- Preheat the oven to 350°F (177°C). Line an 8-inch square baking pan with parchment paper, leaving an overhang on the sides. This will help you lift the blondies out later. You can also spray the pan generously with nonstick spray if you prefer.
- In a bowl, whisk together the flour, baking powder, baking soda, and salt. Set this mixture aside.
- In another bowl, whisk together the melted butter, brown sugar, and vanilla extract until well combined. Add the egg and mix until everything is smooth.
- Slowly add the dry ingredients into the wet mixture and stir until just combined. Fold in the chopped candy bars. The batter will be very thick.
- Spread the mixture evenly into the prepared baking pan.
- Bake in the oven for 24–26 minutes, or until the top is lightly browned. Once baked, remove from the oven and allow to cool completely before lifting them out of the pan and cutting into squares. The blondies can stay fresh at room temperature for up to 1 week when covered.
How to Serve Candy Bar Blondies
Candy Bar Blondies can be served warm or at room temperature. They are delicious on their own but can also be enhanced with a scoop of ice cream or a drizzle of chocolate sauce on top. Perfect for dessert after a meal or as a sweet treat during the day!
How to Store Candy Bar Blondies
To keep your Candy Bar Blondies fresh, store them in an airtight container at room temperature. They will stay good for up to one week. If you want to keep them for longer, you can freeze them in an airtight container for up to three months. Just let them thaw at room temperature before serving.
Tips to Make Candy Bar Blondies
- Make sure not to overmix the batter; mix just until the dry ingredients are combined.
- Use your favorite candy bars for a fun twist—mix and match or swap them with seasonal options.
- For extra flavor, try adding a pinch of cinnamon or a handful of nuts to the batter.
Variation
If you want to make a nutty version, add 1/2 cup of chopped nuts such as walnuts or pecans along with the candy bars. For a more caramel flavor, consider incorporating caramel bits instead of some candy bars.
FAQs
1. Can I use different candy bars?
Yes! You can use any candy bars you like. Just chop them up and mix them into the batter.
2. What should I do if my blondies are too dry?
If your blondies come out dry, it’s likely they were baked too long. Make sure to start checking them at 24 minutes and remove them as soon as they are lightly browned.
3. Can I freeze Candy Bar Blondies?
Absolutely! You can freeze them for up to three months in an airtight container. Just let them thaw at room temperature before enjoying.
