Begin by thoroughly rinsing the blueberries with cold water. Gently pat them dry using a paper towel.
Combine the blueberries, vanilla ice cream, milk, honey, and vanilla extract in a blender.
Blend all the ingredients on high speed until the mixture becomes smooth and creamy. This process should take around 1-2 minutes.
Take a moment to check the consistency. If the milkshake is too thick for your liking, you can add a bit more milk and blend once again.
Taste the milkshake and adjust its sweetness by incorporating more honey if desired.
Once the milkshake reaches your preferred texture and flavour, stop the blending process.
Transfer the blueberry milkshake into serving glasses.
For an extra touch, you have the option to garnish the milkshake with a few fresh blueberries or a drizzle of honey.
