Short answer: Lenny & Larry’s Complete Cookies are the best-tasting protein cookies we’ve eaten — as long as you’re honest about what you’re buying. Roughly 16g of protein rides along with ~400 calories per whole cookie, so this is a better cookie, not a cheaper shake. Judged on those terms, they’ve stayed in our snack rotation for the better part of a decade.
Lenny & Larry’s effectively invented the category back in the 1990s, and the Complete Cookie is still the benchmark other protein cookies get measured against. Here’s the full picture: nutrition, taste, the lawsuit people still ask about, and the UK buying reality.
The nutrition, without the wishful thinking
The numbers that matter, from the packs we’ve bought:
| The Complete Cookie (whole cookie) | |
|---|---|
| Calories | ~400 (varies 10–20 by flavour) |
| Protein | ~16g (pea-protein base) |
| Fibre | ~10g |
| Diet flags | vegan · kosher · gluten-free |
Three honest observations:
- The label says two servings per cookie. Nobody eats half a cookie. Log the whole thing.
- 16g protein for 400 kcal is a treat ratio, not a supplement ratio. A whey shake delivers more protein for a quarter of the calories — if protein-per-calorie is the goal, powder wins. The cookie’s job is being a dramatically better choice than the actual cookie you were about to eat.
- The fibre is the sleeper stat. 10g is a lot, and it’s why one cookie holds you over in a way normal baked goods don’t.
The pea-protein base is what makes the vegan/dairy-free flags possible — and it’s genuinely well-hidden; nothing about the texture says “plant protein”.
How they eat
Soft, dense and large — closer to a bakery cookie than a protein bar pretending. Every flavour we’ve tried lands soft-baked rather than dry, and the size means one cookie feels like a proper snack rather than a mouthful. They hit the odd sweet spot of being satisfying at the end without leaving you rooting for a second.
Our favourites at a glance: Snickerdoodle and Birthday Cake lead, with Peanut Butter Chocolate Chip close behind. The full flavour-by-flavour verdicts — including the ones we’d skip — live in our Complete Cookie flavour ranking.
The lawsuit people still ask about
In 2018 Lenny & Larry’s faced a US class action claiming the cookies contained less protein than the packaging stated. The company settled (a proposed ~$5m deal, reported by Food Navigator) without admitting wrongdoing, maintaining that its testing supported the label. Mars faced a similar suit over its protein bars in the same era — protein-content claims were a lawsuit genre for a while.
Worth knowing as history; it hasn’t put us off. If label-verified protein content is a dealbreaker for you, certified-tested powders are the safer category — see the Informed Choice-certified options in our MyProtein review.
Buying them in the UK
Supermarket coverage is patchy, so Amazon is the practical route — stock and flavour selection rotate, and the search shows what’s actually available today:

Multipacks price dramatically better per cookie than singles from convenience stores — if a flavour works for you, buy the box. For the wider snack drawer, our best protein snacks on Amazon guide covers what sits well alongside them.
Verdict
A decade on, the Complete Cookie is still the protein cookie to beat: honest portion maths (400 kcal — log it all), a genuinely useful 10g of fibre, diet flags that let almost anyone eat it, and — the actual point — it tastes like a cookie you’d choose on purpose. Buy it as the upgrade to your cookie habit, pick flavours from the ranking, and let shakes handle the protein maths.
Frequently asked questions
Are Lenny & Larry's cookies vegan and gluten-free?
Yes on both counts for the Complete Cookie line — the protein comes from a pea-protein base rather than egg, soy or dairy, and the packs we've bought were labelled vegan, kosher and gluten-free. Recipes do get revised, so glance at the pack if an allergy rather than a preference is at stake.
How many calories are in a Lenny & Larry's cookie?
Around 400 for a whole Complete Cookie, give or take 10–20 by flavour — the packs label two servings per cookie, which is worth knowing before you log it as one.
Are they good value as a protein source?
Not really — roughly 16g of protein for ~400 calories is a poor ratio next to a shake. Buy them as a much better cookie, not a cheaper protein supplement: on protein per calorie they lose to whey every time, and on taste they beat every 'healthy' snack we've tried.
Can a Complete Cookie replace a meal?
Calorie-wise it's in light-meal territory (~400 kcal with 16g protein and 10g fibre), and the fibre keeps it surprisingly filling. Nutritionally it's still a cookie — fine as an occasional stand-in on busy days, not a plan.
