Fruit Preparation : Arrange the sliced banana coins and halved strawberries in a single, even layer on the parchment-lined baking sheet. Ensure the fruit pieces are not touching. Place the sheet in the freezer until the fruit is completely solid, at least 4 hours.
Cacao Base Infusion : In the canister of your high-powered blender, combine the frozen banana coins, cacao powder, fine sea salt, vanilla extract, and oat milk. Secure the lid and begin blending on low, gradually increasing the speed. Use the blender’s tamper to press the ingredients toward the blades until a thick, smooth, and uniform chocolate base forms, resembling soft-serve ice cream.
Berry Incorporation : Add the frozen strawberry halves to the chocolate base. Pulse the blender 5 to 7 times, just until the strawberries are roughly chopped and swirled throughout the mixture. Avoid over-blending to maintain distinct pockets of strawberry flavor and color.
Optional Firming : For a scoopable, ice-cream-like texture, immediately transfer the mixture from the blender into a chilled loaf pan. Use a spatula to smooth the top. Cover and return to the freezer for an additional 30 minutes to 1 hour to firm up.
Plating & Finishing : Scoop the cacao-strawberry whip into chilled bowls. Garnish with fresh strawberry slices and a delicate sprinkle of coarse pink Himalayan salt just before serving.
