lwc wrapper class

I'm working on some more LWC learning - trying to understand how a custom wrapper class is displayed in the component.

If I have this APEX, .js, and HTML - the value of field1 is never displayed - can anyone see my issue?

Thanks!

APEX: 
@AuraEnabled(cacheable=true)
	public static wrapperClass  rtnWrapperClass(){
		wrapperClass wrapper = new wrapperClass();
		wrapper.field1 = 'Value for field1';
		wrapper.field2 = 'Value for field2';
		return wrapper;
	}

	public class wrapperClass {
		@AuraEnabled 	public string  	field1		{get;set;}
		@AuraEnabled 	public string 	field2		{get;set;}
		public wrapperClass() {
			this.field1 = field1;
			this.field2 = field2;
		}
	}
.js 
import rtnWrapperClass from '@salesforce/apex/HelperAccount.rtnWrapperClass';

export default class showWrapper extends LightningElement {

    // Return  Wrapper Class
    @wire(rtnWrapperClass)
        wrapperClass;

}

and the HTML: 
<!-- Data from Wrapper Class -->
            <p>Wrapper Class Data...</p>
            <template if:true={wrapperClass.data}>
                <lightning-formatted-text
                    value={wrapperClass.field1}>
                </lightning-formatted-text>
            </template>
