- Same soft center.
- Same gooey chocolate pockets.
- But way less effort.
Just mix it up, bake it once, slice it out… and boom, you’re done.
I first whipped these up on a random day when my sourdough starter was just sitting there, doing nothing.
And if you bake at home, you already know — that extra discard piles up fast. Tossing it out? Nah… not happening.
So I switched it up and threw it into a sweet mix instead.
Didn’t overthink it. Just went for it.
And wow… that first bite hit different.
The bars came out soft, thick, and packed with melty chocolate in every corner.
And that sourdough touch? It doesn’t stand out in a weird way — it just brings this deep, next-level taste that makes these bars way more addictive than your usual batch.
Real talk… once you try these, plain cookie bars just don’t hit the same.
So yeah, if you’ve got extra starter chilling in your kitchen, don’t waste it.
Flip it into something that disappears fast from the tray. 🍫
These bars come out soft right in the middle, with just a light crisp on the edges, and loaded with melty chocolate in every bite.
No scooping. No waiting around.
You just press the dough into a pan, bake it in one go, then slice it up like a pro. Easy win.
If you’re new to baking, this is the kind of recipe that makes you feel like you know what you’re doing from day one.
And here’s a cool little bonus…
That sourdough discard? It’s not just there for fun. Some folks find it sits lighter on the stomach compared to regular bakes. Plus, you’re not tossing it out — which just feels right.
Less waste. More treats. That’s a solid deal.
Need something quick after dinner?
Packing a sweet bite for later?
Or just want something to go with your coffee break?
These bars got you.
Simple. Fast. And yeah… they disappear real quick.
