High calorie smoothies for weight gain
Almost every smoothie recipe on the internet is written to be light. High calorie smoothies for weight gain are written the other way — dense enough to matter, and still drinkable to the bottom of the glass.
Gaining weight takes a sustained surplus, and a smoothie helps because appetite is usually what gets in the way. Make it denser rather than bigger: change the liquid, add a real base, and leave the fruit as it is.
A surplus is a surplus whatever it arrives in. What makes a smoothie useful for gaining is not the ingredients being special but the format — drinking several hundred calories takes a couple of minutes and does not require being hungry, which is the constraint that stops most people who are trying to gain.
The mistake is reaching for volume. A bigger glass fills you up and then goes unfinished, which leaves you worse off than the smaller one you would have drunk. Every blend here is the same two and a bit cups as any other on the site — the difference is what those cups are made of.
Every figure comes from the ingredient amounts in each blend, run through the same maths as the calorie calculator, so a recipe here and the calculator will always land on the same number.
The same blend, three ways
One fruit combination, three decisions. Read the calorie column down the three cards and the ordering of the levers is the entire argument for how these recipes are built.
1 cup water · 1 cup frozen banana (sliced) · 1 cup frozen strawberry. Water and fruit. This is the starting point everything below is measured against.
1 cup whole milk · 1 cup frozen banana (sliced) · 1 cup frozen strawberry. The same fruit on whole milk instead of water. One decision, and nothing else touched.
1 cup whole milk · 1 cup frozen banana (sliced) · 1 cup frozen strawberry · ½ cup rolled oats · 2 tbsp peanut butter. Oats and peanut butter on top of the milk version. This is what a weight-gain blend actually looks like.
How to build one
The largest ingredient in the glass by volume, and the one most recipes treat as an afterthought. Whole milk and oat milk sit far above water and unsweetened almond milk before any fruit goes in — the ranking below is the whole decision.
Oats, nut butter or avocado. This is a fifth of the glass and where the density lives; a blend with no base is a fruit drink whatever else you do to it.
A tablespoon of seeds or nut butter barely changes how full the drink is and moves the total more than an extra fruit would. That ratio is the reason boosts matter more here than anywhere else on the site.
Fruit is for flavor and carbohydrate. Doubling it doubles the volume, fills you up, and adds much less than a single spoon of nut butter — which is exactly the wrong trade when appetite is the constraint.
Liquids, densest first
One cup of each, straight from the ingredient database. This is the first decision and the biggest one.
The guides
Adding calories to a smoothie is easy. Adding them without ending up with a pint of syrup you cannot finish is the part worth getting right.
Eight blends, densest first. The dense ones are a meal you can drink; the lighter ones sit between meals without ruining the next one.
A mass gainer is a surplus with protein attached. Both halves of that are easy to build at home, and the home version is food rather than a powder that tastes like a powder.
Four decisions decide how dense a smoothie is, and they are not the ones most recipes emphasize. Here is each one ranked, with the fruit in its proper place — near the bottom.
This is a real target people search for, so here is the honest version: what it takes, what it tastes like, and why splitting it in two is usually the better plan.
Every fruit ranked by calories, per hundred grams and per typical serving — the two orderings are not the same.
Going the other way?

Work out your own surplus
Add your ingredients one at a time and the calculator sums the calories, protein and fat as you go — so the glass lands where you meant it to.
Open the calorie calculatorEstimates, not advice. Every figure on this page is calculated from published per-100 g reference values and standard household measures, so your own brands, portions and equipment will move it. Nothing here is medical, nutritional or dietetic advice — talk to a qualified professional before acting on it, particularly if you are pregnant, managing a health condition, or feeding a child.
