If the Moon's mass doubled while staying the same distance from Earth, the gravitational force between them would double because F = G M_earth M_moon / r^2 and r is unchanged. (If by "twice its size" you mean diameter doubled at the same density, mass would increase 2^3 = 8 times and the gravitational force would increase eightfold.)
