1In blender, place egg, milk, flour, olive oil and salt. Cover; blend on medium speed 10 seconds, stopping blender frequently to scrape sides, until smooth. Place covered blender container with batter into refrigerator 30 minutes to chill batter.
2When batter is chilled, spray 6 to 8-inch nonstick skillet with nonstick cooking spray. Heat skillet over medium heat. For each crepe, pour 3 tablespoons batter into skillet. Immediately rotate skillet until thin layer of batter covers bottom. Cook, turning once, until lightly browned, 1/2 to 1 minute. Repeat with remaining batter, spraying skillet as needed. Remove cooked crepes to wooden cutting board.
3Continue until all the batter has been used.
4Finally, spread a layer of peanut butter down the center of each crepe. Add a line of jam next to it. Fold the crepe. Serve immediately.
