Preheat your oven to 350 degrees F (about 180 degrees C). Mix 50g white sugar and 2.5g ground cinnamon in a small bowl. Stir in 20g melted butter until combined. Set aside for now.
In a food processor, blend 110g flour, 25g brown sugar, 2.5g ground cinnamon, and 2g salt. Add 55g cold/frozen butter, pulsing until you have pea-sized crumbs.
Mix in 60g sourdough starter or discard and 1.5g vanilla extract. If the dough isn't coming together, add cold water one tablespoon at a time until it does.
Roll out the dough between two layers of parchment paper using a rolling pin to about ⅛ inch thick. The thinner, the better, because that is what makes the cereal crispy and not cake like.
Transfer your dough, still in a parchment paper sandwich, to a baking sheet. Score the dough with a pizza cutter, pastry cutter, or a sharp knife, marking squares but not cutting all the way through. This will make it easy to break into pieces after baking.
Brush the scored dough with the cinnamon sugar mixture you made earlier.
Bake for 12-14 minutes at 350 degrees F (about 180 degrees C), until golden brown and crisp.
Let the cereal cool, then break it into squares. They should separate easily, ready to be enjoyed right away with some milk or as a snack.

once your dough is ready, don't delay rolling and scoring it. If you wait too long, the butter will soften and melt, leading to a less crispy and flaky texture in your cereal.
keep your butter cold. This helps create those flaky, crispy squares we love. If the butter melts before baking, your cereal might end up too dense.
if the mixture you prepared becomes a bit stiff, throw it in the microwave or heat it up a bit before spreading on the dough. On the other hand, try not to heat it up too much to prevent it from melting the butter in the dough before you manage to get everything into the oven.
watch the oven closely! Oven temperatures can vary, and so can baking times. Start checking around the 12-minute mark to prevent over-baking.
