Transfer cottage cheese into a high-performance blending apparatus, processing until achieving a velvety, uniform texture without lumps.

Incorporate peanut butter, selected keto-friendly sweetener, and liquid stevia vanilla essence into the smooth cottage cheese mixture.

Thoroughly blend the ingredients until the mixture develops a consistent, luxurious creamy composition with no visible separation.

Carefully distribute the whipped mixture into elegant serving vessels, ensuring equal portioning.

Without rinsing the blending device, transform frozen berries into a vibrant, silky puree by pulsing until completely liquefied.

Enhance the berry sauce with additional sweetener, briefly mixing to create a harmonious flavor profile.

Artfully cascade the crimson berry sauce across the whipped cottage cheese surface, allowing gentle swirling for visual appeal and flavor integration.

For optimal enjoyment, refrigerate immediately if not consuming right away, preserving the delicate texture and preventing ingredient separation.

When ready to serve, optionally garnish with a light dusting of crushed nuts or a small berry cluster for textural contrast.
