To prepare a stuffed date drops from the 50s baked goods recipe, you'll first need to gather your ingredients. You will need: 1 cup (240 g) rolled oats, 1 tablespoon (15 ml) brown sugar, 3 tablespoons butter, and 1 teaspoon vanilla extract. Preheat the oven to 350?F (177?C) and line two large baking sheets with parchment paper. Cut the dates in half lengthwise, then cut each half into 12 inch (1.3 cm) slices. Place the slices in the prepared baking sheet and bake for 10 to 15 minutes, or until the edges are golden brown. Remove from oven and allow to cool for 5 minutes before slicing.
