Preheat oven to 350°F (180°C). Line rimmed baking sheets with parchment paper.
In the bowl of a stand mixer fitted with the paddle attachment, beat shortening, ½ cup (100 grams) granulated sugar, brown sugar, and vanilla at medium-high speed until fluffy, 3 to 4 minutes, stopping to scrape sides of bowl. Add peanut butter, beating until smooth. Add egg, beating to combine.
In a medium bowl, whisk together flour, baking soda, and salt. Reduce mixer speed to low. Gradually add flour mixture to shortening mixture, beating well after each addition. Beat in cream.
In a small bowl, stir together cinnamon and remaining ¼ cup (50 grams) granulated sugar. Using a 2-tablespoon scoop, scoop dough, and roll into balls. Place dough balls in cinnamon sugar, tossing to coat. Place 2 inches apart on prepared pans. Using a fork, press each ball to ½-inch thickness, making a crosshatch design.
Bake until edges are just beginning to brown, 10 to 13 minutes. Let cool on pans for 5 minutes. Remove from pans, and let cool completely on wire racks. Store in an airtight container for up to 5 days.
