Cinnamon Rolls Bake Dry Around The Edges Of The Pan

A pan of cinnamon rolls rarely bakes evenly. The outer ring browns, firms and dries while the center rolls are still pale and slightly raw at the seam.

Rolls at the edge have an exposed side

A roll in the middle of the pan is surrounded by other rolls on every side. Its only exposed surface is the top.

A roll at the edge has a face against hot metal and receives heat from a direction the interior rolls do not. That side sets and browns much earlier.

The consequence is that the two groups are effectively baking two different recipes in the same dish, at different rates, to a single timer.

Moisture moves outward and leaves

Water evaporating from the interior rolls travels through the soft seams between them and escapes at the perimeter and the top.

The center therefore stays humid and steams, which keeps its surface soft and slows browning. The edge dries and crusts.

This is the same effect that makes pull-apart rolls tender where they touch, but here it works against the pan because the bake is longer.

The filling is not distributed evenly

Cinnamon sugar melts into a syrup during the bake and runs downward and outward. The pan bottom and the perimeter collect it.

Sugar at the edge caramelizes quickly against hot metal, which darkens those rolls further and can burn before the center is done.

Butter in the filling behaves the same way, pooling at the base and frying the bottoms of the outer rolls while the middle sits in a wet layer.

Pan choice changes the spread of the problem

A glass or ceramic dish heats slowly and holds heat gently, which reduces the edge effect but lengthens the bake and can leave the center underdone.

A dark metal pan browns edges fastest and produces the widest gap between the outer and inner rolls.

Spacing the rolls slightly apart rather than packing them tight lets heat reach the sides of the middle rolls, at the cost of the soft torn seam.

Practical corrections work on heat, not time

Lowering the oven temperature and extending the bake narrows the gap, because it gives the center time to reach temperature before the edges dry.

Covering the pan with foil for the first part of the bake traps steam and delays browning until the interior has caught up.

Rotating the pan partway through corrects for uneven ovens but does nothing about this problem, which is caused by the arrangement rather than by the oven.
