Banana Oat Weight Gainer Shake

A very high-calorie shake for people who struggle to gain weight.

Banana Oat Weight Gainer Shake

Gaining weight is easiest with calories you can drink. This shake is built to be big: whole milk, oats, two bananas, and two scoops of whey. Sip it over 20 to 30 minutes if the volume feels like a lot.

  2. Add the protein powder, bananas, honey, almond butter, and cinnamon.
  3. Blend on high for a full minute.
