Chocolate Toffee Bars Recipe
Introduction
These Chocolate Toffee Bars combine a buttery base with sweet melted chocolate and crunchy toffee bits for an irresistible treat. Perfect for sharing at gatherings or enjoying as an afternoon snack, they’re simple to make and delightfully delicious.

Ingredients
- 1 cup butter (softened)
- 1 cup brown sugar
- 1 large egg yolk
- 1 cup all-purpose flour
- 2 teaspoons vanilla extract
- 1 12 oz bag milk chocolate chips
- 1/2 cup toffee bits
Instructions
- Step 1: Preheat oven to 350º F.
- Step 2: Beat together the softened butter, brown sugar, and egg yolk until just combined. Avoid overbeating— you want everything incorporated but not fluffy.
- Step 3: Add the flour and vanilla extract. Mix until just combined to avoid overworking the dough.
- Step 4: Press the mixture evenly into a greased half sheet pan or a 13×9 inch baking dish.
- Step 5: Bake for 20-25 minutes, or until the edges turn golden brown.
- Step 6: Remove from oven and sprinkle the milk chocolate chips evenly over the warm bars.
- Step 7: Let the chocolate chips sit for 5-7 minutes to soften and melt. Alternatively, return the pan to the oven for 2-3 minutes until the chocolate looks shiny. Then gently spread the melted chocolate into an even layer.
- Step 8: Sprinkle the toffee bits evenly over the melted chocolate layer.
- Step 9: Allow the chocolate to set completely before slicing into bars.
Tips & Variations
- For extra flavor, sprinkle a pinch of sea salt over the toffee bits before the chocolate sets to enhance the sweetness.
- Swap milk chocolate chips for dark chocolate for a richer taste.
- If you don’t have toffee bits, finely chopped caramel candies or crushed Heath bars work well.
- Use parchment paper to line the baking dish for easier removal and cleaner edges.
Storage
Store the bars in an airtight container at room temperature for up to 4 days. For longer storage, refrigerate for up to 1 week. Before serving, let chilled bars sit at room temperature for 10-15 minutes to soften slightly. These bars can also be frozen for up to 2 months; thaw overnight in the refrigerator.

FAQs
Can I make these bars gluten-free?
Yes, substitute the all-purpose flour with a gluten-free flour blend measured 1:1. Some blends may change the texture slightly, but the bars will still be delicious.
What if I don’t have toffee bits?
You can replace toffee bits with chopped nuts, crushed caramel candies, or even toffee-flavored sprinkles to achieve a similar crunch and sweetness.

Ingredients
Base
- 1 cup butter (softened)
- 1 cup brown sugar
- 1 large egg yolk
- 1 cup all-purpose flour
- 2 teaspoons vanilla extract
Topping
- 1 12 oz bag milk chocolate chips
- 1/2 cup toffee bits
Instructions
- Preheat Oven: Preheat your oven to 350º F to get it ready for baking the bars.
- Mix Butter, Sugar, and Egg Yolk: Beat together the softened butter, brown sugar, and egg yolk just until combined. Avoid over-beating like with typical cookies; you want the ingredients incorporated but not fluffy.
- Add Flour and Vanilla: Stir in the all-purpose flour and vanilla extract, mixing just until the batter comes together without overmixing.
- Press Batter into Pan: Grease a half sheet pan or a 13×9 inch baking dish. Evenly press the batter into the pan to form a smooth layer.
- Bake the Base: Place the pan in the preheated oven and bake for 20-25 minutes until the edges turn golden and the base is set.
- Add Chocolate Chips: Remove the baked base from the oven, and immediately sprinkle the milk chocolate chips evenly over the warm bars.
- Melt and Spread Chocolate: Let the chocolate chips sit for 5-7 minutes to soften and melt, or optionally return the pan to the oven for 2-3 minutes until the chocolate appears shiny. Then gently spread the melted chocolate into an even layer using a spatula.
- Sprinkle Toffee Bits: Sprinkle the toffee bits evenly over the melted chocolate while it is still warm.
- Set and Slice: Allow the chocolate to fully set before slicing into bars and serving.
Notes
- Ensure butter is softened at room temperature for easy mixing.
- Do not overbeat the batter to maintain a tender texture.
- You can use a half sheet pan or 13×9 inch pan interchangeably.
- For quicker chocolate melting, briefly return to oven instead of waiting.
- Store bars in an airtight container at room temperature for up to one week.
