I cannot find any examples how one would do th

As of September 2019 @bgdnip answer doesnt translate exactly for typescript. I got it working with the following:

const api = new RestApi(this, 'RestAPI', {
    restApiName: 'Rest-Name',
    description: 'API for journey services.',
});

const putIntegration = new LambdaIntegration(handler);

const auth = new CfnAuthorizer(this, 'APIGatewayAuthorizer', {
    name: 'customer-authorizer',
    identitySource: 'method.request.header.Authorization',
    providerArns: [providerArn.valueAsString],
    restApiId: api.restApiId,
    type: AuthorizationType.COGNITO,
});

const post = api.root.addMethod('PUT', putIntegration, { authorizationType: AuthorizationType.COGNITO });
const postMethod = post.node.defaultChild as CfnMethod;
postMethod.addOverride('Properties.AuthorizerId', { Ref: auth.logicalId });

This is from https://docs.aws.amazon.com/cdk/latest/guide/cfn_layer.html#cfn_layer_resource_props

UPDATE October

The above is already out of date and unnecessary and can be achieved with the following with aws-cdk 1.12.0

const api = new RestApi(this, 'RestAPI', {
    restApiName: 'Rest-Name',
    description: 'API for journey services.',
});

const putIntegration = new LambdaIntegration(handler);

const auth = new CfnAuthorizer(this, 'APIGatewayAuthorizer', {
    name: 'customer-authorizer',
    identitySource: 'method.request.header.Authorization',
    providerArns: [providerArn.valueAsString],
    restApiId: api.restApiId,
    type: AuthorizationType.COGNITO,
});

const post = api.root.addMethod('PUT', putIntegration, {
    authorizationType: AuthorizationType.COGNITO,
    authorizer: { authorizerId: auth.ref }
});
