How to Make the Best Toffee Chocolate Bars

Ingredients You’ll Need:

These toffee chocolate bars are packed with flavor from simple pantry staples.

Unsalted butter – Adds richness and a smooth texture.
Creamy peanut butter – This helps create a peanut butter caramel flavor.
Dark brown sugar – Deepens the flavor with its rich molasses notes.
Egg + Egg yolk – Keeps the bars tender and chewy.
Milk & Vanilla extract – Enhances the flavor and moisture.
All-purpose flour, baking powder & sea salt – The foundation for perfect cookie bars.
Toffee bits – Brings a delicious caramelized crunch.
Semisweet chocolate chunks – Melts into the bars for a gooey, chocolatey bite.
Flaky sea salt – Optional but highly recommended for extra depth of flavor.

(Exact measurements are in the recipe card below!)

Step-by-Step Instructions

Preheat & Prep. Set your oven to 350°F. Line an 8×8-inch metal baking pan with parchment paper and lightly grease it with nonstick spray.
Melt & Mix. In a large bowl, melt the butter and peanut butter together until smooth. Stir in the dark brown sugar while still warm. Let the mixture cool slightly.
Whisk in Wet Ingredients. Add the egg, egg yolk, milk, and vanilla extract. Mix until fully incorporated.
Add Dry Ingredients. Stir in the flour, baking powder, and sea salt with a rubber spatula until just combined.
Fold in Goodness. Stir in three-quarters of the toffee bits and chocolate chunks.
Press & Top. Evenly spread the dough into the prepared pan. Sprinkle the remaining toffee bits and chocolate chunks over the top.
Optional: Chill for Best Flavor. Cover and refrigerate the pan overnight (or up to 3 days) for a deeper flavor and better texture.
Bake & Cool. Bake for 26 minutes or until the edges turn golden brown. Let the bars cool in the pan for three hours before slicing (trust me, it’s worth it!).
Enjoy! Cut into squares and serve with a sprinkle of flaky sea salt for extra deliciousness.

Expert Tips for Perfect Peanut Butter Caramel Bars

Don’t skip the chilling step! It helps develop the best texture and flavor.
Use high-quality chocolate. A good Hershey chocolate and toffee bar or semisweet chunks will melt beautifully.
Store properly. Keep bars in an airtight container at room temperature for up to 4 days or freeze for longer storage.

Serving & Storing Tips

How to serve: These bars pair beautifully with a cold glass of milk, a scoop of vanilla ice cream, or a drizzle of warm caramel sauce.
Storing leftovers: Store in an airtight container at room temperature for up to 4 days. If you want them to last longer, freeze in a sealed bag for up to 2 months.
Reheating: Enjoy at room temp or warm in the microwave for 10-15 seconds for a gooey chocolate center.

1. Can I use crunchy peanut butter instead of creamy?

Yes! Crunchy peanut butter adds texture and nutty bites to these toffee chocolate bars.

2. Can I make these bars gluten-free?

Absolutely! Substitute a 1:1 gluten-free flour blend for the all-purpose flour.

3. What if I don’t have toffee bits?

You can chop up a Hershey chocolate and toffee bar or use caramel chips instead!

4. Can I double the recipe?

Yes, simply bake in a 9×13-inch pan and adjust the baking time to around 30-32 minutes.

5. Why do I have to wait 3 hours before cutting them?

It helps the flavors meld together and prevents crumbling—totally worth it!
