Full Ingredients

Dry Ingredients

• 1 3/4 cups (220 g) all-purpose flour
• 1 tsp baking soda
• 1/2 tsp baking powder
• 3/4 tsp fine sea salt (or 1 tsp kosher salt)
• 1/2 tsp ground cinnamon (optional, but lovely with oats and toffee)

Wet Ingredients

• 1 cup (226 g) unsalted butter, softened to cool room temperature
• 1 cup (200 g) packed light brown sugar
• 1/2 cup (100 g) granulated sugar
• 2 large eggs, at room temperature
• 2 tsp pure vanilla extract

Oats & Mix-Ins

• 2 1/2 cups (225 g) old-fashioned rolled oats (not quick or instant)
• 1 1/4 cups (200 g) dark chocolate chunks or chips (60–70% cacao)
• 1 cup (160 g) toffee bits, such as Heath Bits O’ Brickle, or finely chopped toffee bars
• Flaky sea salt, for sprinkling on top (optional but highly recommended)

Step-by-Step Instructions

Step 1: Prep your pans and preheat the oven

Preheat your oven to 350°F (175°C) with a rack in the center. Line 2 large baking sheets with parchment paper. This is important because toffee bits can melt and stick; parchment makes cleanup easy and helps the cookies bake evenly.

If your butter is very cold, cut it into pieces and let it sit out for 15–20 minutes while you gather and measure the other ingredients. Room-temperature eggs will blend more easily, so set those out too if you have time.

Step 2: Whisk together the dry ingredients

In a medium bowl, add the flour, baking soda, baking powder, salt, and cinnamon (if using). Whisk until everything is evenly combined and there are no streaks of baking soda or baking powder. Set this bowl aside. Pre-mixing the dry ingredients helps them distribute evenly through the dough without overmixing later.

Step 3: Cream the butter and sugars

In a large mixing bowl (or the bowl of a stand mixer fitted with the paddle attachment), add the softened butter, brown sugar, and granulated sugar. Beat on medium speed for about 2–3 minutes, scraping down the bowl once or twice, until the mixture looks lighter in color and slightly fluffy. This step incorporates air, which helps give the cookies a nice, chewy texture with gently crisp edges.

Step 4: Add eggs and vanilla

Add the eggs one at a time, mixing on low–medium speed after each addition until just incorporated. Scrape down the bowl as needed so no streaks of egg remain. Pour in the vanilla extract and mix again briefly until the batter is smooth and creamy. Avoid over-beating at this stage; you want everything well combined, but not whipped.

Step 5: Add dry ingredients and oats

With the mixer on low (or using a sturdy spatula), add the dry ingredient mixture to the wet ingredients in two additions. Mix only until you no longer see dry flour. The dough will be fairly thick.

Next, add the rolled oats. Fold or mix on low speed until the oats are evenly incorporated throughout the dough. Scrape all the way to the bottom of the bowl to make sure no pockets of flour or oats are hiding.

Step 6: Fold in chocolate and toffee, then chill

Gently fold in the dark chocolate chunks and toffee bits until they are evenly distributed. Make sure the toffee is not all clumped together in one area.

For thicker, chewier cookies that spread less, cover the bowl and chill the dough in the refrigerator for about 30 minutes. If you are in a hurry, you can bake right away; the cookies will spread a bit more but will still be delicious.

Step 7: Scoop, bake, and cool

Use a 2-tablespoon cookie scoop (about 35–40 g of dough) or a heaping tablespoon to portion the dough onto the prepared baking sheets, spacing the mounds 2 to 3 inches apart. If you can, try to keep any large toffee pieces away from the bare edges of the pan so they do not burn.

Bake one sheet at a time for 11–13 minutes, or until the edges are deep golden and set, but the centers still look slightly underdone and soft. The cookies will firm up as they cool.

As soon as the tray comes out of the oven, if desired, sprinkle each cookie lightly with flaky sea salt to balance the sweetness and enhance the caramel and chocolate flavors.

Let the cookies cool on the baking sheet for 5 minutes, then carefully transfer them to a wire rack to cool completely. Repeat with remaining dough, using cooled baking sheets.

Pro Tips

• Measure flour carefully: If you have a kitchen scale, use it. Otherwise, spoon flour into your measuring cup and level it off. Too much flour makes cookies dry and cakey.
• Use old-fashioned oats: Quick or instant oats will change the texture and make the cookies less hearty. Old-fashioned rolled oats give the best chew and appearance.
• Chill for thicker cookies: A short 30-minute chill keeps the cookies from spreading too much and concentrates the flavors.
• Watch the toffee edges: Toffee melts and can burn if it is right against the metal pan. If you see a piece on the edge of a dough ball, nudge it back on top before baking.
• Do not overbake: Pull the cookies when the centers still look a bit soft. Overbaking will make them crisp instead of chewy once cooled.

Variations

• Nutty chocolate toffee oatmeal cookies: Fold in 1/2–3/4 cup (about 60–80 g) chopped toasted pecans or walnuts along with the chocolate and toffee for extra crunch and a rich, buttery flavor.
• Espresso twist: Add 1–2 tsp instant espresso powder to the dry ingredients. The subtle coffee flavor deepens the dark chocolate and makes the cookies taste extra sophisticated.
• Bar cookie version: Press the dough into a parchment-lined 9×13-inch (23×33 cm) pan and bake at 350°F (175°C) for 22–26 minutes, until golden at the edges and just set in the center. Cool completely and cut into bars.

Storage & Make-Ahead

Once completely cooled, store the cookies in an airtight container at room temperature for up to 4–5 days. To keep them extra soft, you can tuck a small piece of bread or a few marshmallows into the container; replace as they dry out.

For longer storage, freeze baked cookies in a single layer on a tray until firm, then transfer to a freezer bag or airtight container. They will keep well for up to 2 months. Thaw at room temperature or warm briefly in a low oven for that just-baked texture.

You can also freeze the unbaked dough. Scoop dough into balls, freeze on a parchment-lined tray until solid, then store in a freezer bag for up to 2 months. Bake from frozen at 350°F (175°C), adding 1–2 extra minutes to the baking time.
