Introduction
These Chocolate Toffee Bars combine a buttery, soft base with rich milk chocolate and crunchy toffee bits for a perfect treat. Easy to make and irresistibly sweet, they’re great for sharing or a cozy dessert.

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 the oven to 350º F (175º C).
- Step 2: Beat together the softened butter, brown sugar, and egg yolk until just combined. Avoid overbeating; you want the ingredients incorporated, not fluffy.
- Step 3: Add the flour and vanilla extract. Mix until just combined without overmixing.
- Step 4: Press the dough evenly into a greased half sheet pan or a 13×9 inch baking dish.
- Step 5: Bake for 20-25 minutes until the edges turn golden brown.
- Step 6: Remove from the oven and evenly sprinkle the milk chocolate chips over the hot bars.
- Step 7: Let the chocolate sit for 5-7 minutes to melt and become shiny; alternatively, place the pan back in the oven for 2-3 minutes to melt the chocolate.
- Step 8: Gently spread the melted chocolate into an even layer, then sprinkle the toffee bits over the top.
- Step 9: Allow the chocolate to set completely before slicing into bars and serving.
Tips & Variations
- For a richer flavor, use browned butter instead of softened butter in the base.
- Try substituting dark chocolate chips for a less sweet, more intense chocolate layer.
- Adding a pinch of sea salt on top of the melted chocolate enhances the toffee’s sweetness.
- If toffee bits are unavailable, crushed Heath or Skor bars make a great alternative.
Storage
Store the bars in an airtight container at room temperature for up to 5 days. For longer storage, keep them refrigerated for up to 2 weeks. To soften before serving, bring to room temperature or warm gently in the microwave for 10-15 seconds.

FAQs
Can I use margarine instead of butter?
Butter is preferred for flavor and texture, but margarine can be used in a pinch. Just make sure it’s stick margarine designed for baking.
Do I have to melt the chocolate chips in the oven?
No, you can let the chocolate chips melt from the residual heat of the bars on the counter, but returning the pan to the oven for a few minutes ensures a smooth, even layer.

- 2 teaspoons vanilla extract
Topping
- 1 12 oz bag milk chocolate chips

Instructions
- Preheat Oven: Preheat your oven to 350º F (175º C) to prepare for baking the bars.
- Mix Butter, Sugar, and Egg Yolk: In a mixing bowl, beat together the softened butter, brown sugar, and egg yolk until just combined, making sure not to overbeat; the mixture should be smooth but not fluffy.

- Top with Toffee Bits: Sprinkle the toffee bits evenly over the melted chocolate layer.
- Cool and Set: Allow the chocolate topping to fully set and harden before slicing the bars into desired pieces.
