Why you’ll love it:

This 2000 calorie smoothie recipe is decadent, rich, and filled with healthy ingredients like banana, avocado, oats, dates, and peanut butter!

It’s a weight gain smoothie you can fool good about! The only added sugar is from the protein powder, but you could easily use a sugar-free one if you like. I use a chocolate plant-based protein powder.

Frozen bananas and ice thicken the smoothie, while dates sweeten it. Dates are a good source of fiber and antioxidants. I like to serve this 2000 calorie shake with whipped cream and cacao nibs. Yum!

Key Ingredients:

frozen bananas, avocado, oats, protein powder, avocado, coconut milk, peanut butter, dates.
  • Frozen bananas – I keep these on hand in my freezer at all times. Simply cut a banana into slices and drop it into a zip-top bag. Freeze overnight or up to three months.
  • Peanut butter – A good way to add calories and protein!
  • Chocolate protein powder – You can use any brand/type of protein powder (I use plant-based). Just be sure you like the taste of it. All protein powder brands taste a little different.
  • Cocoa powder – I use dark cocoa powder or Dutch cocoa powder. It’s dark smooth, and rich!
  • Avocado – A whole avocado provides healthy fats and about 250 calories. It’s also super creamy in texture!
  • Oats – Oats are a nutritious whole grain that taste great in smoothies!
  • Dates – Look for Medjool dates. Be sure to remove the pit before you add them to the smoothie. A date is a tropical stone fruit that’s been dried to concentrate it’s sweetness.
  • Coconut milk – Canned coconut milk is a great way to pack in calories. One cup boasts close to 500 calories!
  • Milk – Any kind of milk works great, but whole or oat milk provide the most calories.
  • Ice – I like to add ice to this smoothie since it’s full of so many rich ingredients! The ice lightens it up some and gives it a frosty texture.

How to make a 2,000 calorie smoothie:

This 2000 calorie shake is a breeze to make! Here’s what you need to do:

Combine ingredients: In the pitcher of a high-speed blender, combine the frozen bananas, peanut butter, protein powder, cocoa powder, avocado, oats, dates, ice, coconut milk, and whole milk.

Blend until smooth: Blend until the mixture is smooth and creamy. If it’s too thick add a splash of whole milk and blend some more. I prefer to blend my smoothies thick, then adjust the consistency as necessary. Add more milk to thin it out.

Enjoy immediately: Pour into a large glass and enjoy immediately! I like to top mine with whipped cream.

High Calorie Smoothie Ingredients:

The key to a high-calorie smoothie is using high-calorie, nutrient-dense ingredients! Here’s plenty of good options to try:

  • Nut butters – A serving of nut butter packs in about 200 calories! Try peanut, cashew, or almond butter.
  • Seeds – Ground flax or chia seeds.
  • Avocado – One medium avocado boasts 250 calories.
  • Full-fat cottage cheese – One cup provides 222 calories and makes a smoothie super creamy!
  • Canned coconut milk – Coconut milk quickly increases calorie count. One cup packs in 450 calories!

Recipe Tips:

  • For best results, use a high-speed blender. You don’t have to take out a second mortgage to buy a decent blender. In fact, I’ve had my Ninja blender for 8+ years! I highly doubt a cheap blender with low wattage would last that long. A good blender is an investment.
  • Weight gain smoothies don’t have to be massive! The key is to find high-calorie, nutrient-dense ingredients to pack in the calories.
  • If the smoothie’s too thick, add more liquid. I prefer a thick smoothie, but you can easily thin it out with more milk. Just remember, you can always add more but you can’t take it out.
