Preheat oven to 350-degrees Fahrenheit (170-degrees Celsius)
Add the first 9 ingredients into a large bowl, stirring well to form a semi-stiff dough.
Scoop out approximately golf ball size dough balls and form into acorn shapes.
Place the cookies onto parchment-lined baking sheets.
Bake in a preheated oven for 18-20 minutes or until the cookies are slightly browned on the bottom.
*Note - the cookies should not spread in shape and they also will not darken in color, except on the bottom.
Remove the baked cookies from the oven and cool completely on a wire rack.
Continue the same process with the remaining cookie dough.
In a medium bowl, melt the chocolate chips (except the reserved ones) in a microwave oven on medium/low power, in 30-second increments, stirring occasionally. Continue doing so until the chocolate is smooth and creamy.
Dip the cooled cookie (tops only) into the melted chocolate (as the acorn cap) and place a reserved chocolate chip in the center of each cap.
Gently dip the melted chocolate acorn cap into the ground peanuts and then place the cookies on a parchment-lined baking sheet until the chocolate is set.
Notes
Wrap these cookies well and freeze for up to two months, if needed.
