tl;dr solution:
When your ship is in the air (when it's higher than its normal hovering level because it's been launched off a bump or ramp), jam your left thumbstick left-right-left, and if A) you do this quickly enough, B) your ship has enough energy, and C) your ship has enough height, your ship should do a barrel roll.
Long Solution:
1a. You can do this on almost any map, but it'll help if you choose a track that allows your ship to get a little hang time - I chose the track Modesto Heights in the Blitzed Race Campaign (Event 01/08) of the Fury Campaign. Modesto Heights is the Single Race in the upper-righthand-most selectable hexagon, which you'll unlock after a win or two.
1b. On this same race select screen, set your AI Difficulty to Novice by pressing Square, if you're not already on the novice difficulty.
2. Choose a ship.
3. Now, in order to do a barrel roll, you need to quickly move your Left Thumb Stick Left-Right-Left OR Right-Left-Right while your ship is in the air.
4. If you chose the Modesto Heights map, about 35 or 40 seconds into the race, you'll round a left-hand turn and reach the large jump that'll launch your ship into the air for a solid couple of seconds. As soon as your ship launches up the jump, jam your left thumbstick left-right-left (or vice versa) as quickly as you can.
5. As long as you do this while you're in the air, your ship should do a barrel roll, and the trophy will pop. If it doesn't pop during the race, finish the race, and it should pop as you're exiting back to the menu.
Things to keep in mind:
You can barrel roll on any track that lets your ship get a little air, but I chose this track because, near the end of each lap, there's a large jump that launches your ship for a solid couple seconds of hang time.
Single Races are three laps long, so you'll have multiple attempts available in that race mode.
You will not be able to do a barrel roll if your ship is hovering at normal race height.
You will not be able to do a barrel roll if your ship's energy is low. Your energy bars are the lined parentheses-looking things at the top center of your screen.

This is a very easy trophy that you're guaranteed to get during your campaign playthrough. As you probably already know, you barrel roll by moving the 
left and right quickly while your ship is in the air (went up a ramp etc) you can also use 
and 
but I find it impossible with them. This performs a barrel roll and gives the ship a speed boost. You can't barrel roll if your health is less than 15 as barrel rolling takes 15 of your health to do it. Upon successfully landing your first barrel roll, the trophy will unlock shortly afterwards.

(for those who don’t know) from the take-off you need to quickly press left, right, left or right, left, right... the higher the take-off and the more successful the roll, the greater the acceleration!
