Cold coffee, banana, cacao, and vanilla give this oat-milk smoothie a coffee-shop style flavor. A date adds sweetness and cauliflower contributes body. It is a useful chilled blend when plain brewed coffee is already available without flavored syrup or cream.

Measured ingredient amounts adjust with servings. “To taste” amounts and directions stay as written.
Ingredients
- 0.75 cup plain brewed coffee, cooled
- 1 banana, peeled and frozen
- 1 pitted medjool date
- 1 teaspoon pure vanilla extract
- 0.75 cup cauliflower florets, cooked and cooled, then frozen
- 0.25 cup unsweetened oat milk
- 0.5 tablespoon cacao powder
Directions
- Pour the measured liquid into the blender. Add the softer prepared ingredients first, keeping the frozen pieces separated so they can move toward the blades instead of forming a solid block above them.
- Add the remaining edible ingredients, including the measured fruit, nuts, seeds, or spices listed for this recipe. Blend until evenly combined. Use the machine instructions to choose a suitable speed, and stop before checking texture or scraping the jug.
- Taste a small spoonful after blending. If the mixture is too thick to pour, add cold water one tablespoon at a time and blend briefly again. Divide the base batch into 1 serving and enjoy promptly.
Notes
Prepared ingredients are required; additional cooking, cooling, freezing, brewing, or soaking time is excluded from the active prep estimate. Serving volume and nutrition totals are not measured.

Tips and ingredient notes
Cool coffee completely and choose decaf if preferred. Prepare cauliflower as its package directs, then cool it. The coffee stays noticeable, so select one you enjoy without adding a separate sweetened flavoring.
Use unsweetened cacao or cocoa rather than an instant chocolate-drink mix. The latter can contain sugar and other ingredients that alter the recipe. Break up large powder clumps before blending, then taste only after the powder is fully dispersed in the liquid.
Use plain brewed coffee that has cooled completely. A flavored or sweetened coffee product adds ingredients the recipe does not account for. Stronger coffee remains more noticeable in the finished smoothie; keeping the measured volume constant makes flavor comparisons easier.
Ingredient health benefits
