Simple and delicious rhubarb cake recipe.
While a standard fruit crisp relies on a heavy oat topping to balance tart stalks, this structure uses a tender butter cake base to absorb the sharp juices of spring vegetation. Baking with freshly harvested stalks introduces a crisp snap and vibrant tartness that heavily influences the final crumb structure. Thawed frozen stalks, conversely, release significantly more cellular water upon heating, which can create dense pockets in the batter unless drained thoroughly or tossed with an extra pinch of flour to absorb excess moisture.
Standard metal skewers or wooden toothpicks serve as the primary diagnostic tools for this 9x13 inch pan. Insert the testing implement directly into the center of the crumb mass rather than near the sugary topping. Pull the tester out immediately; wet batter clinging to the surface indicates the interior requires more time in the 350 degrees F heat, while a few moist crumbs signal proper completion.
