How to Prevent Cookies From Spreading

Triple Chocolate Cookies

Here are some helpful tips to prevent cookies from spreading:

Don’t Overbeat the Batter

Far too many recipes advise bakers to simply “Cream butter and sugar until smooth”. So many people just turn on the mixer and go check their e-mail.

When you beat butter and sugar, those little crystals of sugar create air pockets between the butterfat. The more you beat, the more air you incorporate (those trapped air pockets steam open and expand in the oven). That’s great for a nice, light cake…but not for most cookies. So when the recipe says, ““Cream or beat butter and sugar”, just mix them for about 30 seconds, until well-combined.

Use Ungreased Baking Sheets

Unless the recipe says so, bake cookies on an ungreased or unbuttered baking sheet. You’re creating a slippery surface if you do, which causes cookies dough to slide. I use parchment paper, which has just enough friction for cookies to stay-put without sliding around, but they don’t stick.

Measure Ingredients Properly

I know this is a big duh!, but adding more liquid or less flour than a recipe indicates makes a big difference. When people tell me, “I can’t bake”, I never understand that. I mean, how difficult is “8 ounces of butter” or “3 large eggs”? It’s not like a piece of meat that you need to guess and adjust cooking times. Baking is a no-brainer.

Don’t change ingredients either. Using extra-large eggs in place of large eggs means you’ve added more liquid. Using anything other than all-purpose flour (or whatever is called for) can also be problematic.

Check Your Fat

Most butter is about 80% fat, meaning the rest is roughly 20% water. When used in a batter, that water liquefies, and voila!. You can use a ‘European-style’ butter, which has a higher percentage of fat and remains more stable when baked. Examples of this include Plugra.

Some recipes use vegetable shortening instead of butter, which is another alternative (although I don’t personally use vegetable shortening). Vegetable shortening is 100% percent fat, which means there’s little water so things stay in place better when baked (it’s why pie dough made with shortening is flakier…there’s little water to saturate and toughen the flour.)

If you choose to replace butter in your recipe with vegetable shortening, find one without trans-fats, which are now available.

Check Your Oven Temperature

Every oven is completely different. I had a someone call me at 11pm one night to tell me her Peanut Butter Cookies took 10 minutes to bake instead of 9 minutes, as indicated by the recipe. Buy an oven thermometer and check the accuracy of your oven.

If you put cookies in an oven that’s not hot enough, they’ll droop and spread before firming up.

Chocolate Tempering: How To Temper Chocolate

Homemade Rocky Road, from The Great Book of Chocolate, Enrobed in Tempered Chocolate

How do you temper chocolate, and why do you do it? The short answer is that chemically, chocolate is composed of lots of different little crystals (six to be exact) but the desirable ones are called beta crystals. The development and formation of these beta crystals are what makes well-tempered chocolate.

If the cocoa butter rises to the surface, some people commonly think their chocolate has gotten moldy and toss it out. If you’ve done that, you’ve tossed out perfectly good, but unattractive, chocolate.

As you can see, there is a dull white sheen on the surface of this piece of chocolate. And that’s what happens to chocolate that’s not properly tempered: the cocoa fat rises to the surface and “blooms”, making it unappealing and unattractive. When you buy chocolate, like a candy bar or chocolate in bulk, the chocolate has been tempered and it should be nice and shiny and snap when you break it. Yet if you leave your candy bar in a warm car and later open it up, often it’ll become white and gray. The heat caused your chocolate to lose it’s temper. When you buy chocolate for baking, it should arrive well-tempered. (If buying pistoles in bulk, they may be dull from becoming scratched during transport, which is not to be confused with untempered.) But once you chop it up and melt it, the beta crystals change, the chocolate loses its temper, and you’ll need to re-temper it again if you plan to use it as a coating.

Pages and volumes of technical research have been written about tempering chocolate, but here are the main reasons for all you home cooks out there:


  • To avoid fat (and sugar) bloom, characterized by unappealing white streaks or blotches on the surface.
  • To raise the melting temperature of finished chocolate so it doesn’t melt on contact with your fingers.
  • To preserve the keeping quality of chocolate by stratifying the fat.
  • To cool chocolate quickly. Tempered chocolate cools fast, within 5 minutes.
  • Tempered chocolate will shrink slightly when cooled, which allows it to slip out of molds easily.
  • To give chocolate a glossy, shiny appearance, and a crisp, clean snap when you break it.

As I’ve said, you don’t need to temper chocolate if you’re going to bake a chocolate cake or make chocolate ice cream. The only time you need to temper chocolate is when you need an attractive, shiny coating for candies that will sit at room temperature. You can get around tempering by dipping chocolates in melted, untempered chocolate and storing them in the refrigerator. Just remove them from the refrigerator a few minutes prior to serving them. The coolness of the refrigerator will stratify the cocoa fat and it won’t bloom.

Theo Chocolates

There are many different methods for tempering chocolate. Some are a bit complicated, and some are really messy, especially for home cooks. I rely on a thermometer, which is foolproof. It’s best to use a dark chocolate that is no higher than 70% in cocoa solids. Higher percentage chocolates (and some artisan bean-to-bar chocolates) can be quite acidic, and may behave differently.

I developed a simple 3-step method that’s a snap for home cooks. All you need is an accurate chocolate thermometer, although a good digital thermometer will work.


Tempering Chocolate

1. The first step is to melt the dark chocolate in a clean, dry bowl set over simmering water, to about 115º-120º F (46º-49ºC.)

2. Remove from heat and let it cool to the low 80ºs F (27ºC.) Drop a good-sized chunk of solid (and tempered) chocolate in, which provides insurance by ‘seeding’ the melted chocolate with good beta crystals. While cooling, stir frequently. Motion equals good crystallization, aka, tempering.

3. The last step is the most important: It’s bringing the chocolate up to the perfect temperature, where it’s chock-full of those great beta crystals. This occurs in most dark chocolates between 88° and 91° F (31º-32ºC.)

(Milk chocolate tempers at 86º-88ºF, 30º-31ºC. Please note that chocolates can vary, so check with manufacturer if unsure about your particular chocolate.)

4. Remove what’s left of the chunk of ‘seed’ chocolate, and your chocolate is dip-worthy: you can dip all the chocolates you want and all will be perfectly tempered. Don’t let it get above 91° F (32ºC) or you’ll have to begin the process all over again. If it drops below the temperatures, rewarm it gently to bring it back up.
