In a bowl, mix together the pancake mix, olive oil, and milk.
Once the dough is mixed together completely, ball it up, then begin rolling it with a roller to match the size of your tart pan. Sprinkling flour on the dough helps keep the dough from sticking to the roller, making it easier to spread.
Lay the spread dough into the pan, making sure the bottom is flat. Remove any dough that is protruding from the sides of the pan.
Poke some air holes in the dough with a fork, then bake in the oven at 180°C for 20 minutes. Keep an eye on the crust while baking and make any necessary adjustments needed to bake evenly. When finished, allow the crust to cool, then remove it from the pan.
