Halloween Candy Cookie Bars

Pro tips

• Don't overmix the batter after adding wet ingredients—stir just until combined to keep bars tender and chewy.
• Chop candy bars into uniform, small pieces so they distribute evenly throughout the batter.
• Underbake slightly; centers should look barely set when removed from the oven—carryover heat will firm them up as they cool.
• Cool bars completely in the pan before cutting for clean edges and easier handling.

Substitutions

• All-purpose flour → cake flour (for extra tenderness, reduce by 2 tablespoons)
• Brown sugar → granulated sugar (texture will be slightly less chewy)
• Chopped mini candy bars → chopped nuts, wafer cookies, or caramel pieces (replaces candy with textural variety)

Storage & make-ahead

Store cooled bars in an airtight container at room temperature for up to 5 days, or freeze for up to 1 month.

What types of mini candy bars work best?

Use any chopped mini candy bars you have on hand—Snickers, Twix, Reese's, and Milky Ways all work well. Mix varieties for texture contrast.

Can I add nuts or caramel pieces instead of candy?

Yes. Substitute up to ¾ cup chopped nuts, wafer pieces, or caramel candy pieces for a different flavor and texture.

How do I know when the bars are done?

Bake until the edges are set and lightly golden but the center still appears slightly underbaked. They continue to set as they cool.

How should I store these bars?

Keep in an airtight container at room temperature for up to 5 days. They're best enjoyed within 2 days for optimal chewiness.

Can I make these ahead?

Yes, bake and cool completely, then store covered. Bars can be made 1–2 days in advance.
