These cookies are what happens when a fudgy brownie and a tender meltaway cookie share the same baking sheet. The outside is soft and barely crisp, while the inside stays rich and almost creamy.
I started making them when I wanted a chocolate cookie that did not need chilling or rolling. One bowl, a handful of pantry staples, and about thirty minutes later they are cooling on the rack.
What goes into the dough
This is a butter and powdered sugar base, so use the good stuff. The chocolate flavor comes from both cocoa powder and a little melted dark chocolate, which gives a deeper brownie taste than cocoa alone.
- Unsalted butter. Softened so it creams quickly with the sugar and carries the chocolate flavor.
- Powdered sugar. Dissolves into the butter and creates the signature tender crumb that melts on your tongue.
- Egg yolk. Adds richness and holds the dough together without making it cakey.
- Unsweetened cocoa powder. The backbone of the brownie flavor. Dutch-process will give a darker color and milder taste.
- Melted dark chocolate. A small amount deepens the flavor and keeps the centers fudgy.
- Cornstarch. The secret to the meltaway texture. It softens the flour and keeps the cookies from turning tough.
- All-purpose flour. Just enough to bring the dough together without making it dry.
- Baking powder. A tiny lift so they are not dense bricks.
How they bake up
- Cream the butter and sugar. Beat the softened butter and powdered sugar together until the mixture looks pale and fluffy, about two minutes. This step is what creates the tender base.
- Add the wet ingredients. Mix in the egg yolk, vanilla, and cooled melted chocolate until the batter is smooth and glossy.
- Stir in the dry ingredients. Whisk the flour, cornstarch, cocoa powder, baking powder, and salt in a separate bowl, then add to the wet mixture. Beat on low just until a soft dough forms.
- Scoop and shape. Use a tablespoon to portion the dough into balls. Roll them lightly and place two inches apart on a parchment-lined baking sheet. Flatten each ball slightly with the bottom of a glass so they bake evenly.
- Bake. Bake at 350 degrees F (175 degrees C) for ten to twelve minutes until the tops look set and the edges are firm but not dark. They will still be soft in the center.
- Cool and dust. Let the cookies rest on the pan for five minutes, then move to a wire rack. Once fully cool, dust generously with powdered sugar.
The cornstarch trick
Cornstarch is what separates a meltaway from a standard sugar cookie. It interferes with gluten formation, so the crumb stays delicate even if you accidentally over-mix a little. If you are out of cornstarch, you can substitute an equal amount of additional all-purpose flour, but the texture will be slightly less tender. For more chocolate cookies with a soft center, try fudgy brownie cookies.
Why powdered sugar beats granulated
Powdered sugar contains a small amount of cornstarch and dissolves almost instantly into the butter. That means the dough does not need to be beaten as long, which keeps the cookies from becoming tough. It also helps the tops crack slightly in the oven, giving them that familiar brownie look. If you want an even deeper chocolate experience, brownie stuffed chocolate cookies take the same idea a step further.
Baking cues that matter
These cookies stay light in color, so do not wait for them to turn dark brown. Pull them when the tops look matte and the edges feel set to a light touch. They will firm up as they cool on the pan. Moving them too soon can cause cracking. If you like a crinkled brownie top, tap the pan firmly on the counter right when it comes out of the oven.
Make-ahead and storage
The dough keeps in the fridge for up to three days if you want to bake fresh cookies later. Let it sit at room temperature for fifteen minutes so it is soft enough to scoop. Baked cookies stay soft in an airtight container for five days. You can also freeze the baked cookies in a single layer for up to two months. Thaw them uncovered so the powdered sugar does not weep. For another easy chocolate cookie, chocolate chip brownie cookies freeze just as well.
A note on cocoa
Natural cocoa powder gives a sharper, more acidic chocolate flavor, while Dutch-process cocoa produces a darker cookie with a smoother, almost earthy taste. Either works here, but do not use hot cocoa mix, which contains sugar and milk powder and will throw off the ratio. King Arthur Baking has a helpful guide to baking with cocoa powder if you want to learn more.
FAQs
- Can I use granulated sugar instead of powdered sugar?
You can, but the texture will change. Powdered sugar dissolves faster and contains cornstarch, which helps create the tender meltaway crumb. Granulated sugar will give you a firmer, more traditional cookie.
- Do I need to chill the dough?
No. This dough is soft but sturdy enough to scoop straight after mixing. If your kitchen is very warm and the dough feels greasy, a ten-minute rest in the fridge will make it easier to handle.
- Can I freeze the baked cookies?
Yes. Let them cool completely and store in an airtight container with parchment between layers. Freeze for up to two months and thaw uncovered at room temperature.
- Why are my cookies dry and crumbly?
Overbaking is the most common cause. These cookies should look slightly underdone when you pull them from the oven. Another culprit is measuring flour by scooping directly from the bag; use the spoon-and-level method instead.
- Can I add chocolate chips or nuts?
Absolutely. Fold in up to half a cup of mini chocolate chips or finely chopped walnuts after the dry ingredients. Keep the pieces small so the tender dough still holds together.
- How do I know when they are done?
The tops should look matte and dry, and the edges should feel set when lightly touched. The centers will still be soft. They will continue to firm up as they cool on the baking sheet.
- What makes these 'meltaway' cookies?
The high ratio of butter and cornstarch to flour creates a very tender, fragile crumb that literally melts in your mouth. The powdered sugar and lack of granulated sugar also contribute to the silky texture.
