Add the greek yogurt and dry pudding mix to a bowl. The pudding mix acts as a thickening and flavoring agent that transforms the yogurt's texture from dense to light and fluffy. Start whisking immediately to break up any lumps in the pudding powder and distribute it evenly throughout the yogurt.

Continue whisking vigorously for 1-2 minutes until the mixture transforms into a light, airy fluff. I find that the key is really committing to the whisking motion—this incorporates air into the yogurt and activates the pudding mix to create that signature fluffy consistency. Stop whisking occasionally to check the texture; you want it noticeably lighter and fluffier than when you started.

Add the 2 tablespoons of water and a pinch of salt, whisking gently to incorporate. The water helps lighten the fluff further and makes it easier to whisk to the desired fluffy consistency, while the salt enhances all the flavors. If you prefer an even airier texture, add water gradually and whisk more; if you like it thicker, use less water or whisk less vigorously.

Divide the greek yogurt fluff into serving bowls and add your desired toppings right away. This dessert is best enjoyed fresh when the texture is at its fluffiest, so serve within a few minutes of whisking. Popular toppings include fresh berries, granola, honey drizzle, or coconut flakes.
