Begin by adding your frozen, mixed berries to the blender. Pour in the two servings of kefir (whether you prefer almond or plain) and add one cup of berries for extra flavor. Next, slice a half banana and drop it into the mix. Measure out a teaspoon of butter to introduce a subtle creaminess, then add half a cup of liquid along with several teaspoons of vanilla extract. This carefully layered approach ensures every ingredient—from the tang of fermented milk kefir to the sweetness of banana—is perfectly balanced.

Secure the blender lid and blend on high speed until the mixture turns silky smooth. The aim is to achieve a texture reminiscent of a drinkable yogurt, where the almond kefir and frozen fruits merge into a light, slightly fizzy consistency. The process is simple: let the blender work its magic until the vanilla and berry flavors are fully combined.

Once the blend is smooth, pour your kefir smoothie into tall glasses and enjoy immediately to benefit from its fresh probiotics. Alternatively, if you’d like a refreshing twist, pour the mixture into popsicle molds and freeze for a delightful treat on a warm day.
