Empty contents of Ulf Brand’s Red Velvet Mug Cake Mix in a bowl. Add Oil and Water according to package instructions. Mix just till no dry powder is visible. Empty contents of Ulf Brand’s Vanilla Mug Cake Mix in another bowl and prepare as instructed. Place spoonfuls of the vanilla batter all over the red velvet batter and gently swirl it with a knife / toothpick, taking care not to mix too much. Pour in to 2 microwave friendly mugs and cook on ‘high’ for 60 seconds.
Pro tip : Add 2 tsp of Chocolate Chips to the batter to add some crunch and make it more chocolatey.
