Check for liquid: Open the cottage cheese and check the surface for pooled liquid. If it looks watery, tip it into a mesh strainer for a minute or stir the liquid back in for a looser texture.
Stir the curds smooth: Add the cottage cheese to a mixing bowl and stir hard with a fork for about 15 seconds, until the curds break down and the texture looks closer to a loose custard.
Blend for a smooth base: For a smoother, yogurt-like base, transfer the cottage cheese to a blender and blend for 30 to 45 seconds, scraping the sides once, until it looks glossy instead of grainy. Skip this step if you like a bit of curd texture.
Add vanilla and cinnamon: Stir in the vanilla extract and ground cinnamon until the mixture turns a pale golden color and smells lightly sweet and warm.
Sweeten with honey: Add the honey a tablespoon at a time, tasting as you go since the tang of cottage cheese varies between brands.
Divide into bowls: Spoon the sweetened cottage cheese into two serving bowls and smooth the tops with the back of a spoon.
Add the berries: Scatter the mixed berries over the top of each bowl, pressing a few gently into the cottage cheese so the juice begins to bleed at the edges.
Top with crunch: Sprinkle the granola and chia seeds evenly over the berries for a crunchy, textured finish.
Finish and serve: Drizzle each bowl with a little more honey or a spoonful of peanut butter, then grab a spoon and dig in.
