For the best texture, underbake the cookies slightly so they stay soft when sandwiched; they continue to set as they cool. Chill the filling for 10 minutes if it seems too soft to pipe, and ensure cookies are fully cool to prevent the cheesecake layer from melting. Use a cookie scoop for uniform size so sandwiches match up neatly. For stronger peanut flavor, swap 2 tablespoons of flour with powdered peanuts or peanut flour, and for gluten-free, use a 1:1 baking blend. The assembled cookies keep well covered in the refrigerator for up to 4 days and can be frozen for 1 month; thaw in the fridge before serving.
