Ingredients

Dry Mix (goes in the jar):

1 3/4 cups all-purpose flour
1/2 teaspoon baking soda
1/2 teaspoon baking powder
1/2 teaspoon fine salt
3/4 cup packed light brown sugar
1/2 cup granulated sugar
1 cup chocolate chips (semisweet or milk)
1/2 cup chopped walnuts or pecans (optional)
1/2 cup rolled oats or crushed pretzels (optional for crunch)

Wet Ingredients (added by the baker when making cookies):

1/2 cup (1 stick) unsalted butter, melted and slightly cooled
1 large egg
1 1/2 teaspoons vanilla extract

Step-by-Step Instructions

Prep the jar: Use a clean, dry 1-quart (32 oz) mason jar with a tight lid. Any moisture = clumpy sugar = sadness.
Mix the dry base: In a small bowl, whisk the flour, baking soda, baking powder, and salt. This prevents uneven spread and random baking chaos later.
Layer like a pro: Add the flour mixture to the jar first.
Tap the jar to level. Follow with brown sugar, then granulated sugar, then chocolate chips, and any optional add-ins. Pack lightly after each layer with the back of a spoon for clean stripes.
Label it: Attach a card that says: “Add 1/2 cup melted butter, 1 egg, 1 1/2 tsp vanilla.
Chill 20 minutes. Bake at 350°F (175°C) for 10–12 minutes.” Include yield and storage. Future you will thank present you.
When ready to bake: Preheat oven to 350°F (175°C).
Line baking sheets with parchment.
Combine wet ingredients: Whisk butter, egg, and vanilla until smooth. Butter should be melted but not hot, or you’ll scramble the egg—bonus protein? Not today.
Mix it up: Pour jar contents into a bowl, break up any sugar clumps, and stir to combine.
Add the wet mixture and fold just until no streaks of flour remain. Don’t overmix or the cookies turn tough.
Chill briefly: 20 minutes in the fridge. This hydrates the flour and keeps cookies from spreading into pancakes.
Scoop and bake: Drop 2-tablespoon balls (about 1.5 inches) onto the sheet, 2 inches apart. Bake 10–12 minutes until edges are golden and centers look slightly underdone.
Cool smart: Let cookies rest on the sheet for 5 minutes, then move to a rack.
They finish setting as they cool—patience equals chewy perfection.
Serve or gift: If gifting the jar, tie a ribbon around the lid and add a cute tag. If you’re “taste testing,” well, no one needs to know how many.

Storage Instructions

For the jar mix: Store at room temperature, away from heat and light, up to 3 months. If using nuts, aim for 6–8 weeks for best freshness.
For baked cookies: Keep in an airtight container at room temperature for 3–4 days with a slice of bread or a sugar-saving disc to retain softness.
Freeze dough: Scoop, freeze on a tray until solid, then store in a freezer bag up to 3 months.
Bake from frozen at 350°F, adding 1–2 minutes.
Freeze baked cookies: Wrap tightly and freeze up to 2 months. Thaw at room temp or give them a warm-up in a 300°F oven for 4–5 minutes.

Health Benefits

Let’s be real—this is dessert. But there are some silver linings. Oats add fiber, and dark chocolate brings antioxidants.

Nuts (if you include them) offer healthy fats and a bit of protein, which help with satiety.

Want to optimize a bit? Use 50% whole wheat pastry flour for extra fiber without turning the cookies into hockey pucks. You can also reduce sugar by 2–3 tablespoons and still get great texture.

Small tweaks, big impact, IMO.

Common Mistakes to Avoid

Skipping the flour whisk: If the leaveners aren’t evenly mixed, you’ll get weird cookie shapes and uneven lift.
Packing the brown sugar too hard: Overpacked sugar throws off the moisture balance. Lightly pack—don’t compress like you’re building a sandcastle.
Overmixing the dough: Stir until just combined. Overmixing develops gluten and turns chewy into rubbery.
Hot butter + cold egg: That’s how you get scrambled bits.
Cool the butter and use a room-temp egg for a smooth emulsion.
No chill time: Chilling controls spread and improves chew. Twenty minutes isn’t optional; it’s insurance.
Overbaking: Pull when the centers look slightly underdone. They firm up as they cool—trust the process.

Different Ways to Make This

Triple Chocolate: Use 1/2 cup cocoa in place of 1/2 cup flour, plus white and dark chocolate chips.
Add 1 tablespoon milk if dough seems dry.
Salted Caramel Pretzel: Swap 1/2 cup chips for caramel bits and add 1/2 cup crushed pretzels. Finish with flaky sea salt after baking.
Oatmeal Raisin Glow-Up: Replace 1/2 cup flour with oats, add 2/3 cup raisins, and 1 teaspoon cinnamon. Nutmeg if you’re fancy.
Peanut Butter Chip Party: Use peanut butter chips and chopped peanuts.
For PB lovers, add 2 tablespoons powdered peanut butter to the flour mix.
Gluten-Free Friendly: Use a 1:1 gluten-free baking flour with xanthan gum. Chill a bit longer to help structure.
Dairy-Free: Replace butter with melted coconut oil or vegan butter. Choose dairy-free chocolate chips.
Espresso Chip: Add 1 tablespoon instant espresso powder to the flour layer.
The coffee intensifies the chocolate. FYI: It won’t taste like a latte—just deeper.

FAQ

What size mason jar do I need?

A 1-quart (32 oz) jar fits the layers neatly. If you add lots of mix-ins, keep them to about 1 cup total so the lid still closes without an arm workout.

Can I halve the recipe?

Yes.

Use a pint (16 oz) jar and halve all ingredients. Baking time usually stays the same, but check at 8–9 minutes.

Why did my cookies spread too much?

Likely warm dough, overly soft butter, or not enough flour. Chill the dough 20–30 minutes, and make sure your flour was measured correctly (spoon and level, don’t scoop).

Can I make this ahead for gifts?

Absolutely.

Make multiple jars assembly-line style. They keep for up to 3 months in a cool, dry spot. Add a cute tag with baking instructions and a “best by” date.

Do I have to use both baking powder and baking soda?

Yes, for best texture.

Soda helps browning and spread; powder adds lift. The combo gives you that chewy edge, soft middle magic.

How many cookies does this make?

About 18–22 cookies using 2-tablespoon scoops. Smaller scoops yield more; just reduce the bake time by 1–2 minutes.

Can I reduce the sugar?

You can safely cut 2–3 tablespoons from the granulated sugar without wrecking texture.

Go further, and the cookies may dry out or bake unevenly.

What if I don’t have chocolate chips?

Chop a chocolate bar, use M&Ms, toffee bits, or even dried cranberries. Mix and match—this recipe is forgiving.
