There are few things more comforting than a freshly baked oatmeal cookie, but when you elevate it with buttery toffee bits and a sprinkle of flaky sea salt, you create something truly magical. These Salted Toffee Oatmeal Cookies are the perfect marriage of chewy, sweet, salty, and crisp.

Whether you’re baking for a potluck, gifting homemade goodies, or just looking for a cozy weekend treat, these cookies are guaranteed to impress.

Ingredients You’ll Need

1 cup unsalted butter, softened
Essential for that rich, buttery base. Room temp helps with proper creaming.
1 cup brown sugar, packed
Adds moisture and a deep molasses flavor.
½ cup granulated sugar
Balances the brown sugar for sweetness.
2 large eggs
Helps bind the dough and create structure.
1 teaspoon vanilla extract
Adds warmth and enhances the toffee flavor.
1 ½ cups all-purpose flour
The foundation of the dough.
1 teaspoon baking soda
Leavening for just the right spread.
½ teaspoon salt
Balances the sweetness.
3 cups old-fashioned oats
Do not substitute with quick oats — texture is key!
1 cup toffee bits (like Heath Bits o' Brickle)
Adds crunchy, buttery caramel bits throughout.
Sea salt, for sprinkling
Flaky sea salt like Maldon or kosher salt works best.

Step-by-Step Instructions

1. Preheat and prepare.
Preheat your oven to 350°F (175°C) and line baking sheets with parchment paper. This helps the cookies bake evenly and prevents sticking.

2. Cream the butter and sugars.

In a large mixing bowl, cream together the softened butter, brown sugar, and granulated sugar.
Beat on medium speed for 2–3 minutes until light and fluffy. This step is crucial for texture.

3. Add eggs and vanilla.

Beat in the eggs one at a time, scraping the bowl as needed.
Add the vanilla extract and mix until smooth.

4. Mix dry ingredients.

In a separate bowl, whisk together the flour, baking soda, and salt.
Gradually add the dry mixture into the wet ingredients, mixing just until combined.
Avoid over-mixing to keep the cookies tender.

5. Stir in oats and toffee.

Fold in the old-fashioned oats and toffee bits by hand or on low speed until evenly distributed.
The dough will be thick and slightly sticky.

6. Chill the dough (optional but recommended).

Cover the dough and chill in the fridge for at least 30 minutes.
This helps prevent spreading and deepens the flavor.

7. Shape the cookies.

Scoop tablespoon-sized portions of dough and roll into balls.
Place them 2 inches apart on the prepared baking sheets.
Lightly flatten the tops with your fingers or the back of a spoon.

8. Add a finishing touch.

Sprinkle each cookie with a pinch of flaky sea salt.
Don’t skip this step — it really brings out the flavor!

9. Bake.

Bake for 10–12 minutes, or until the edges are golden and the centers look set but slightly soft.
They will continue to firm up as they cool.

10. Cool.

Allow the cookies to cool on the baking sheet for 5 minutes.
Then transfer them to a wire rack to cool completely.

Serving and Storage Tips

Salted Toffee Oatmeal Cookies are perfect served warm from the oven with a glass of milk, or cooled and packed into lunchboxes or cookie jars.

Storage:

Store in an airtight container at room temperature for up to 5 days.
For longer storage, freeze the baked cookies in a single layer, then transfer to a bag or container for up to 2 months.

Reheating:

Warm individual cookies in the microwave for 10-15 seconds for that fresh-baked softness.

Freezer Tip:

Freeze scooped dough balls on a baking sheet. Once solid, transfer to a zip-top bag and freeze for up to 3 months. Bake directly from frozen — just add 1-2 minutes to baking time.

Helpful Notes

Butter Temperature: Make sure your butter is soft but not melted. This ensures the cookies hold their shape.
Browning Option: For a richer flavor, brown the butter first and let it cool before using.
Toffee Substitution: Can’t find toffee bits? Chop up a toffee bar like Heath or Skor.
Mix-ins: Add ½ cup of chopped nuts or chocolate chips for variety.
Oats Tip: Old-fashioned oats give the best chewy texture. Avoid quick oats or steel-cut oats.
Salt Variations: If you don’t have flaky sea salt, use a tiny pinch of kosher salt instead. Avoid table salt, which is too fine.

Frequently Asked Questions

1. Can I make these gluten-free?
Yes! Use a 1:1 gluten-free all-purpose flour and ensure your oats are certified gluten-free.

2. What if I don’t have toffee bits?
Chop up a few toffee candy bars or use butterscotch chips for a similar vibe.

3. Do I have to chill the dough?
No, but it helps the cookies hold their shape and enhances flavor. Highly recommended.

4. Can I make these into cookie bars?
Yes! Press the dough into a greased 9x13-inch pan and bake for 22-25 minutes. Cool and slice.

5. Why are my cookies spreading too much?
Check your butter wasn’t too warm or your flour was under-measured. Chilling helps prevent spreading.
