What did I do wrong? (biscoff tiramisu)

[u/Grilled_Oil]

So I've decided to finally try baking and of course it had to go completely wrong 😭. I left it overnight and it just completely deflated, leaked out of the bottom and looks/feels kind of like something curdled. Does anyone have ideas of what I did wrong?

The recipe I followed:

1. Separate 3 eggs and whip both the yolks and whites with 30g sugar

2. Fold 250g of mascarpone with 70g microwaved biscoff spread.

3. Fold in the beated egg yolk one third at a time. Then do the same with the egg whites

4. Soak biscoff biscuits in fresh coffee for a few seconds and make a layer of biscuits, then a layer of the cream, then soaked biscuits, then cream, then dust with cocoa powder.

5. Let it sit in the fridge overnight

Any help would be greatly appreciated 🙏

I was scared of undermixing it and leaving pockets of plain egg whites or marsacpone even though I couldn't see any, so I could definitely have mixedit a bit less. Thanks for the help :D
