Kitchen Help
- → Can I make this skillet cookie ahead of time?
Yes, you can prepare the dough up to 24 hours in advance and store it refrigerated. Let it come to room temperature for 15 minutes before baking. The baked skillet also reheats beautifully in a 300°F oven for 10 minutes or over low heat on the stovetop.
- → What makes this different from regular oatmeal cookies?
The mashed bananas create extra moisture and natural sweetness while keeping the texture softer than traditional oatmeal cookies. Baking in a cast-iron skillet produces crispy edges with a warm, pudding-like center that's perfect for scooping.
- → Can I use quick oats instead of old-fashioned rolled oats?
Old-fashioned oats provide better texture and structure. Quick oats will make the final result softer and less chewy. If you only have quick oats, reduce the amount to 1 cup to prevent the batter from becoming too loose.
- → How do I know when it's done baking?
The edges should be golden brown and set, while the center will still have a slight jiggle when gently shaken. A toothpick inserted near the edges should come out mostly clean, but the center may still have melted chocolate on it.
- → What can I serve with this skillet dessert?
Warm servings pair perfectly with vanilla ice cream, whipped cream, or a drizzle of caramel sauce. For extra indulgence, top with chocolate sauce or a sprinkle of sea salt while still warm to enhance the banana and chocolate flavors.
- → Can I freeze the unbaked dough?
Freeze the dough directly in the skillet wrapped tightly with plastic wrap and foil for up to 3 months. Thaw overnight in the refrigerator before baking as directed. Alternatively, freeze individual portions and bake in ramekins for single servings.
