Uncover and clip a candy thermometer on the pan and cook until temperature reaches 240F. Watch closely to prevent boiling over. Immediately remove from heat once it reaches temperature.

  6. Attach splash cover to mixing bowl and turn Bakery Chef to low. Slowly pour hot syrup through splash cover spout. Once all syrup has been added, turn mixer to high and whip until lukewarm and thick, approximately 7 to 8 minutes. Add vanilla at very end.
