Tips
Watch the browned butter carefully during cooking. It transitions from golden to burnt quickly. Remove when it smells toasty and looks amber, not dark brown. This controls the final flavor intensity.
Chill the browned butter fully before creaming with sugars. Warm butter won't incorporate properly and will result in greasy dough instead of a tender crumb.
Measure half and half gradually when frosting. Start with 1 tablespoon, beat, then add more as needed. This prevents overly thin frosting that won't coat and hold the cashew halves.
Good to Know
Airtight container at room temperature up to 5 days. Unfrosted baked cookies freeze up to 2 months.

FAQ
Can I make the dough ahead and freeze it?
Yes. Shape dough into balls, freeze on a baking sheet, then transfer to a freezer bag for up to 1 month. Bake directly from frozen, adding 1-2 minutes to baking time. Thaw frosting before using.
What if my browned butter looks separated or grainy?
This indicates overcooking or uneven heat distribution. The browned butter is still usable in flavor but may affect dough texture slightly. Stir well before measuring. For best results, start over with fresh butter and medium-low heat.
How long do these cookies stay fresh?
Unfrosted baked cookies keep 5 days in an airtight container. Frosted cookies are best eaten within 3 days as frosting may soften slightly. Unfrosted cookies freeze well for 2 months; add frosting after thawing.
