Laravel use MAX on join statement

I'm trying to find how can i use MAX on laravel QueryBuilder or Eloquent join statement, for example:

$userShoppings = \DB::table('shoppings')
    ->join('products', 'shoppings.product_id', '=', 'products.id')
    ->select('shoppings.*', 'products.name','products.amount','max(shoppings.ordering_count)')
    ->where('shoppings.user_ordering_ip', request()->ip())
    ->get();

in this code i want to get max ordering_count from shoppings table on select method, but i get this error:

Column not found: 1054 Unknown column 'max(shoppings.ordering_count)' in 'field list' 

could any body help me to solve this problem?
