Step 1

Adjust oven rack to upper-middle position and heat oven to 450 degrees. Line rimmed baking sheet with parchment paper. Whisk flour, baking powder, baking soda, sugar, salt, and pepper together in large bowl. Microwave cream and garlic in separate bowl until just warmed to body temperature (95 to 100 degrees), 60 to 90 seconds, stirring halfway through microwaving. Using rubber spatula, gently fold cream mixture and tomatoes into flour mixture until soft, uniform dough forms.

Step 2

Using greased ⅓-cup dry measuring cup, drop 12 level scoops of batter about 1 inch apart on prepared sheet. Brush biscuit tops with tomato oil, then sprinkle evenly with za’atar.

Step 3

Bake until biscuits are starting to turn light golden brown, 14 to 18 minutes, rotating sheet halfway through baking. Transfer biscuits to wire rack and let cool for 5 minutes. Serve warm or at room temperature.
