When do I press the chocolate kiss into the cookie?
Right after the cookies come out of the oven, while they are still hot and puffy. Press gently until the cookie cracks slightly around the edges. That is the look.
How do I keep the kisses from melting?
They will soften from the heat, but they should mostly hold their shape. Use regular milk chocolate kisses (not extra creamy), and do not put the tray back in the oven after the kiss goes on. If your kitchen runs warm, chill the unwrapped kisses in the fridge while the cookies bake.
Do I need to chill the dough?
Usually no. If your dough feels oily, very soft, or your kitchen is hot, chill it for 20 to 30 minutes so the cookies bake thicker and do not spread too much.
Can I use natural peanut butter?
I do not recommend it here. Natural peanut butter can separate and make the dough greasy, which leads to spreading and crumbly cookies. Stick with a creamy, no-stir style for reliable blossoms.
Why did my cookies turn out dry?
Most common culprits are too much flour (scoop and level, or weigh it), baking too long, or using a very dry peanut butter. Pull them when the edges look set but the centers still look slightly underdone.
Can I make them gluten free?
Yes, swap the all-purpose flour for a 1:1 gluten free baking blend that contains xanthan gum. Results vary by brand, so start with a reputable blend labeled for baking (and especially good for cookies). The texture will be slightly more tender and a bit crumblier, but still very good.
