How to pass value from attribute lightning component to apex controller without apex

Question

I have a component with an attribute. I try to pass the value to the controller without succes. How do I achieve this.

Aura component

    <aura:attribute name="currentUser" type="User"/>

<force:recordData aura:id="recordLoader" recordId="{!$SObjectType.CurrentUser.Id}"  fields="Return_URL__c" targetFields="{!v.currentUser}"/>
     {!v.currentUser.Return_URL__c}

Controller

let userCustomField = component.get("v.userRecord").Return_URL__c;

The field is rendering correctly in the component. What am I mising. Thanks in advance
