FAQs
How do I make the cookies extra fudgy?
Use high-quality cocoa powder and don’t overbake them—remove them from the oven when they are just set.
Can I use milk instead of heavy cream for the ganache?
Heavy cream creates the richest texture, but you can use whole milk for a lighter version.
Do I need to chill the dough before baking?
No, but chilling for 15-30 minutes can help if your dough is too sticky.
Can I make these cookies without the ganache?
Yes! They’ll still be delicious, but the ganache adds an extra layer of richness.
What type of cocoa powder works best?
Unsweetened Dutch-processed cocoa powder gives the best deep chocolate flavor.
Can I use a boxed brownie mix?
Yes! Substitute the dry ingredients with a brownie mix, then adjust the wet ingredients accordingly.
How do I get perfectly round cookies?
Use a cookie scoop for even portions and shape them gently with a spoon right after baking.
Can I substitute butter with oil?
Butter gives the best flavor, but you can use an equal amount of vegetable oil for a slightly different texture.
What’s the best way to apply sprinkles?
Sprinkle them over the ganache while it’s still wet so they stick well.
