Slice the peach and measure all ingredients so everything is ready for blending. Using frozen mango is important because it helps create a thick smoothie base that holds toppings well.

Add frozen mango, Greek yogurt, milk, and vanilla extract to the blender. Blend on high speed until the mixture becomes smooth and creamy.

Check the texture of the smoothie mixture. It should be thick enough to scoop with a spoon. If it is too thick to blend properly, add a small splash of milk and blend again briefly.

Pour the smoothie mixture into a bowl. Top with sliced peaches, raspberries, sliced almonds, coconut flakes, and chia seeds. Serve immediately while the bowl is cold and creamy.
