woocommerce_add_to_cart_fragments

function my_custom_fragments( $fragments ) {
    // Add custom fragment
    $fragments['.my-custom-cart-element'] = '<div class="my-custom-cart-element">' .
        WC()->cart->get_cart_contents_count() . ' items</div>';

    return $fragments;
}

Theme-registered fragments:
