Been working on your summer body? Not anymore. 

In a culinary pairing for the history books, McDonald’s Australia has today launched a limited edition run of a one-of-a-kind dessert; a Tim Tam McFlurry. The diarrhea-in-waiting dish is available exclusively on UberEats today for one week, before it hits stores nationwide on December 1. 

The McFlurry kick-starts what Macca’s says is their biggest summer campaign yet, promising a handful of future collaborations and menu items once the limited edition Tim Tam run is fully digested. I’m personally awaiting the return of the chicken Big Mac, but my waistline is thankful for its absence in the meantime.

“At Macca’s, we believe great combinations make summer so special,” McDonald’s Marketing Director said in a statement, “whether that’s sun and surf, friends and family, or TimTam and McFlurry.”

Feast your eyes (and your stomachs) on all the creamy goodness above.
