>>97098591Pistachios on top might hint at pistachios inside.
Otherwise any kind of simple cake is possible.
maybe pumpkin, or almond, lemon, banana etc.
Really hard to tell if it's not cut open.
In any case no large darkened chunks of anything poke out, so it's probably not made with apples or raisins. They would leave wet, dark spots on the outside.
The surface looks rather dark, but that could hint at the baking process as much as the interior coloration.
At the sides I think I am detecting a hint of green, which might be the suspected pistachio, or maybe green tea used as a dye and flavoring.
