How to make Twix Cookie Bars

Ingredients:

  • 1 cup (2 sticks) salted butter (room temperature)
  • 1 cup (4.5 ounces) powdered sugar
  • 2 cups (10 ounces) all-purpose flour
  • 1 teaspoon pure vanilla extract
  • 6 tablespoons salted butter
  • ⅛ teaspoon salt
  • ½ cup light corn syrup
  • 1 cup (7.5 ounces) granulated sugar
  • 1 cup heavy whipping cream (divided)
  • 1 teaspoon pure vanilla extract
  • 1 ¼ cups (8 ounces) milk or dark chocolate (see note)
  • ⅓ to ½ cup (3.5 ounces) heavy whipping cream (see note)

Directions:
For Crust Layer:

  1. Preheat your oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment, leaving an overhang to lift the bars out later.
  2. In a bowl, cream together 1 cup (2 sticks) of room-temperature salted butter and 1 cup powdered sugar until light and fluffy—about 2–3 minutes. Stir in 1 teaspoon vanilla.
  3. Fold in 2 cups all-purpose flour until the dough comes together. Press evenly into the prepared pan, smoothing the top with a spatula or the bottom of a measuring cup.
  4. Bake for 18–20 minutes, or until the edges are barely golden. Remove from the oven and let cool slightly while you make the caramel.

For Caramel Layer:

  1. In a medium saucepan over medium heat, combine 1 cup granulated sugar and ½ cup light corn syrup. Stir gently just to mix, then let the mixture come to a simmer without constant stirring—use a spatula to nudge the edges if needed—until it turns a deep amber color.
  2. Reduce heat to low and carefully whisk in 6 tablespoons salted butter and ⅛ teaspoon salt until melted and smooth.
  3. Warm 1 cup heavy whipping cream (you’ll use it divided). Slowly pour about half of the warm cream into the sugar mixture, whisking constantly to avoid splatters and to keep the caramel smooth. When the caramel calms, add the remaining cream and 1 teaspoon vanilla extract, whisking until glossy and thickened—about 1–2 minutes.
  4. Pour the caramel over the cooled crust, spreading to an even layer. Let it cool at room temperature until it’s set but still slightly tacky—about 30–45 minutes. For a quicker set, chill briefly in the fridge.

For Chocolate Layer:

  1. Chop or chop-ready your 1 ¼ cups (8 ounces) milk or dark chocolate and place in a heatproof bowl.
  2. Heat ⅓ to ½ cup heavy whipping cream (depending how soft or firm you want the ganache) until steaming but not boiling. Pour the hot cream over the chocolate and let sit for a minute, then stir gently until smooth and glossy. If needed, add a splash more cream to reach a spreadable consistency.
  3. Pour the chocolate ganache over the set caramel and spread evenly. Allow the bars to come to room temperature, then chill for 30 minutes to fully set the chocolate.
  4. Use the parchment overhang to lift the slab from the pan. Cut into squares with a sharp knife—wipe the blade between cuts for cleaner edges.

How to serve Twix Cookie Bars
Serve chilled or at room temperature with a tall glass of milk, coffee, or sweet tea. These bars are wonderful for potlucks, a picnic basket, or a quiet afternoon treat with someone you love. A little napkin for sticky fingers is a must.

How to store Twix Cookie Bars
Keep bars in an airtight container in the refrigerator for up to 5 days. For longer storage, freeze in a single layer on a tray until firm, then wrap tightly and store up to 2 months. Thaw in the fridge before serving.

Tips to make Twix Cookie Bars

  • Warm the cream before adding to hot sugar to reduce splatter and help the caramel come together silky-smooth.
  • If your caramel is too thin, simmer a minute longer; if it’s grainy, strain and gently reheat with a little cream.
  • Use good-quality chocolate—it makes a difference in texture and flavor.
  • Let the crust cool a touch before pouring caramel to avoid soaking it too thin.
  • For clean slices, chill the whole pan well and use a hot, dry knife wiped between cuts.

Variations (if any)

  • Nutty Twist: Sprinkle lightly toasted pecans over the caramel before topping with chocolate for a Southern crunch.
  • Salted-Caramel Bars: Sprinkle flaky sea salt on the chocolate before it sets to balance the sweetness.
  • Candy Swap: Top with chopped bits of your favorite candy bars for a playful finish.

FAQs
Q: Can I use store-bought caramel instead of making it?
A: Yes, you can. Warm it gently so it spreads smoothly, but homemade caramel has a depth and warmth you’ll remember—worth the little extra time.

Q: Will these be too soft if I use milk chocolate?
A: Milk chocolate is softer than dark, so use the higher end of the ⅓–½ cup cream range for a firmer set, and chill thoroughly before cutting.

Q: Can I make these gluten-free?
A: You can substitute a 1:1 gluten-free all-purpose flour blend for the crust, but texture may vary slightly. Press the dough gently and monitor baking time.

Q: My caramel seems grainy—what happened?
A: Grainy caramel often means sugar began to crystallize. Try reheating with a bit of cream and whisking until smooth, or start fresh and stir less while the sugar dissolves.

Q: How many bars does this recipe make?
A: Cut into 24 small squares or 12 larger bars—adjust to your crowd and appetite.
