Ingredients:
- 1 cup creamy natural peanut butter, packed
- ½ cup granulated sugar
- ½ cup light brown sugar, packed
- 1 large egg (room temperature)
- 1 teaspoon pure vanilla extract
- 1 teaspoon baking soda
- ¼ teaspoon fine sea salt
- ½ cup high-quality raspberry or strawberry jam/preserve
Instructions:
- Preheat the oven to 350°F (175°C). Line two baking sheets with parchment paper.
- In a large bowl, combine the peanut butter, granulated sugar, and brown sugar. Beat with an electric mixer until just combined and slightly creamy, about 1 minute.
- Add the egg and vanilla extract. Beat until the mixture is uniform and smooth, scraping down the sides of the bowl. Do not overmix.
- Sprinkle the baking soda and salt over the dough. Mix briefly (10-15 seconds) until the leavening agent is fully incorporated.
- Cover the bowl with cling film and refrigerate the dough for a minimum of 30 minutes. This chilling process prevents excessive spreading.
- Use a cookie scoop (approx. 25g/1.5 tbsp) to portion the dough. Roll the portions into smooth balls and place them 2 inches (5 cm) apart on the prepared baking sheets.
- Using a fork, gently press down on each cookie ball to create a flat disc, making the traditional criss-cross hash mark pattern. (Dip the fork in sugar or water between presses if the dough sticks.)
- Bake for 12 to 14 minutes, rotating the trays halfway through, until the edges are golden brown and slightly set, but the centres still look soft.
- Let the cookies cool on the baking sheet for 5 minutes before carefully transferring them to a wire rack to cool completely. Ensure they are entirely cool before assembly.
- Once cool, match up pairs of cookies of similar size. Spread approximately 1–1.5 teaspoons of jam on the flat side of one cookie.
- Gently press the second cookie on top to form the sandwich. Serve immediately or store in an airtight container.
