COOKIES WITH JELLY IN THE MIDDLE RECIPES

Steps:

• Arrange racks in upper and lower thirds of oven; preheat to 350°F. Line 2 rimmed baking sheets with parchment paper.
• Beat egg with a whisk in a medium bowl. Add peanut butter and sugar and whisk until fully incorporated and smooth. Drop mounds of dough by the tablespoonful onto parchment-lined baking sheets, spacing about 2" apart. Lightly press tops of cookies with tines of a fork, making a crosshatch pattern. Sprinkle with salt, if using. Bake cookies, rotating trays halfway through, until golden brown, 10–12 minutes. Transfer to a wire rack and let cool slightly. DO AHEAD: Cookies can be baked 3 days ahead. Store in an airtight container at room temperature.

Steps:

• In a medium saucepan, combine the sugar, butter, cocoa, milk, and vanilla. Bring to a slow boil and simmer until the sugar is completely dissolved. Remove from the heat.
• Stir in the peanut butter and 2 1/2 cups oats. The mixture should be thick; stir in additional 1/2 cup oats if too runny. Let the mixture stand for about 10 minutes to cool.
• Line a baking sheet with wax paper or parchment paper. Drop the mixture by heaping tablespoonful onto the lined sheet. Let the cookies stand at room temperature for 1 hour to firm up. Store in an airtight container.
