A perfect balance of tart and sweet, this cobbler combines winter cranberries with strawberries for a bright filling with a buttery sugar cookie topping.
Prepare. Preheat oven to 375°F with rack in center position. Line a baking sheet with foil to catch any drips.
Mix. In a large bowl, combine cranberries, strawberries, sugar, cornstarch, vanilla, orange zest, and salt. Pour into an 8 or 9-inch square baking dish.
Start. Cover the fruit mixture with foil and bake for 20 minutes to release juices and start the thickening process.
Make Topping. While the filling bakes, beat butter and sugar with an electric mixer for 2-3 minutes until fluffy. Add egg yolk and vanilla, and beat 1 minute more. Add flour, baking powder, and salt, mixing just until combined.
Top. Remove hot filling from oven and drop cookie dough on top by tablespoonfuls, spacing evenly.
Bake. Return to oven and bake uncovered for 40-50 minutes until the topping is golden brown and the filling is bubbling.
Cool. Let rest for at least 20 minutes before serving. Delicious warm or at room temperature with vanilla ice cream.
Notes
The filling should stay a little tart to balance the sweet cookie topping. If you prefer it sweeter, increase the sugar in the filling to 2/3 cup.
