Preheat oven to 425ºF. Line a 9x13” baking sheet (or deeper baking pan) with parchment paper.
Make the beef topping:
Heat oil in a large skillet over medium-high heat. Add beef and remaining ingredients. Cook, stirring occasionally until beef is browned and cooked through, about 5 minutes.
Make the crust:
In a large bowl, whisk together the flour, baking powder, baking soda and salt.
Grate the butter into the flour mixture and whisk again to combine.
Measure in the buttermilk and switch to a wooden spoon or silicone spatula to fold the ingredients gently together until a shaggy dough forms. It will not be totally uniform, and that's ok.
Spoon dough onto prepared baking sheet. Use dampened hands to press the dough evenly into the pan. Bake the crust for 10 minutes.
Top par-baked biscuit crust with pizza sauce, cheese, beef and pepperoni, and finish with more cheese, if desired. Return pan to oven and bake for about 10 minutes more, until golden and bubbly. Top with torn basil.

Notes
TIPS:
The fastest way to make this pizza is to start with the crust so that you can prep the rest of the ingredients while it is partially baking for 10 minutes.
Use the "Metric" button above, place your bowl on a scale, and weigh everything directly into the bowl. Just tare the scale (or power off and back on to reset the weight to zero) between ingredients. Saves dirtying so many measuring cups.
