Old-Fashioned Cherry Squares

Why This Old-Fashioned Cherry Squares Works

During mixing, the soft butter, sugar, and eggs trap a lot of tiny air pockets. That fluffy batter is what lets the bars rise a bit and stay tender instead of dense. The flour and baking powder give the batter enough structure so it can hold the cherry filling without sinking, but it still stays soft when baked.

Once the pan goes in the oven, the bottom layer of batter starts to set first. It firms up into a cake-like base that can support the heavy cherry pie filling. As the cherries heat, the filling loosens a little and spreads into the gaps, but the set bottom layer keeps it from leaking through. The dollops of batter on top slowly spread and bake around the cherries, so there are pockets of cake and pockets of fruit.

By the time it is golden, the eggs and flour have fully set and locked everything together. Cooling in the pan lets the bars firm up so they slice cleanly, while the cherry layer stays soft and a little jammy in the middle.

Mistakes To Avoid

Spreading all the batter in the pan at once instead of saving some for the top makes the bars bake like a solid cake layer with a wet cherry layer sitting on it. The cherry filling then sinks in and can make the bottom gummy while the top dries out and turns tough.

Letting the bars bake until the toothpick is completely clean from the cherry layer leads to overbaking. The edges turn hard and dry, and the top can get too dark while the middle still feels a bit sticky from the filling, which is actually normal.

Skipping the step of creaming the butter and sugar until light and fluffy leaves the batter dense and heavy. In the oven, this batter doesn’t rise much, so the bars come out flat and compact instead of soft and slightly cakey.

Stirring the flour mixture in for too long after it’s added causes the batter to tighten up. During baking, this overworked batter sets into a chewy, bready texture instead of a tender crumb.
