Small muffins are easier to overeat than to count. Knowing the calorie range by size and type helps you enjoy them without guilt or guesswork, especially if you’re watching your weight or tracking macros.
Small muffin calories overview
A typical small standard muffin (about 2 oz / 55 g) has roughly 150–200 kcal. This is an average across basic flavors like plain, blueberry, or simple chocolate chip. Commercial nutrition databases list about 187 kcal for 1 small muffin, with most calories from refined carbs and fat.
For mini muffins, the numbers drop per piece but add up quickly by portion:
- General mini muffin: about 60–110 kcal each, depending on brand and ingredients.
- One common reference shows ~64 kcal for a 17 g mini muffin, while grocery mini muffins like almond poppy or blueberry mini muffins are around 100–110 kcal each.
Are muffins ok for weight loss?
Muffins can fit into a weight‑loss plan if you treat them as an occasional treat and control portions:
- Small/mini muffins are preferable to jumbo café muffins, which can reach 400–700+ kcal each.
- Choosing whole‑grain, lower‑sugar recipes (or homemade versions) reduces calorie density and improves fiber, making them more filling for the same calories.
The biggest trap is mindless snacking—three mini muffins at ~100 kcal each is ~300 kcal, similar to a whole balanced snack or small meal.
Serving size of mini muffins
Most bakery and grocery nutrition sheets define 1 mini muffin as a serving (about 15–25 g).
However, realistic eating patterns often look like:
- Home/office snack: 2–3 mini muffins (approx. 200–300 kcal).
- Kids’ snack packs (like “little bites” style): often 4 mini muffins per pouch, typically around 180–220 kcal per pouch, depending on brand and flavor (chocolate chip tends to be on the higher end).
For tracking, decide whether your “real” serving is 1, 2, or a full pouch and log accordingly.
Chocolate muffin & chocolate chip mini muffin calories
Chocolate generally pushes calories up due to cocoa, extra sugar, and chocolate chips:
- Small chocolate muffin: usually near the upper range of small muffins, around 180–220 kcal depending on fat and sugar content.
- Chocolate‑chip mini muffins: one grocery example shows 180 kcal for 46 g (≈ 1–2 small minis), and another chain’s double chocolate mini muffin is ~110 kcal per mini muffin.
As a rule of thumb:
- Plain/fruit mini: ~60–100 kcal each.
- Chocolate / double chocolate mini: ~100–120 kcal each.
Costco muffin calories (regular & small)
Costco’s muffins are famously calorie‑dense:
- Regular full‑size Costco bakery muffins (8‑pack style) are widely reported in the 410–460 kcal per muffin range, depending on flavor (chocolate, blueberry, etc.).
- Older/jumbo formulas and some chocolate varieties have historically tested even higher, often cited as 600+ kcal per muffin in independent posts and brand comparisons, which aligns with typical jumbo muffin data.
For Costco “small” muffin” style products:
- Member discussions and rough breakdowns suggest “small” Costco muffins still sit around 200–250+ kcal each, because they are denser and richer than many grocery minis, even if lighter than the full jumbo versions.
Without a label, safest practice is to:
- Treat a Costco small chocolate muffin as at least 200 kcal, possibly more if particularly moist or frosted.
- Assume an 8‑pack of regular Costco chocolate muffins provides roughly 3,300–3,600 kcal total (410–460 kcal × 8).

FAQ
How many calories in a small muffin?
A small muffin (~2 oz / 55 g) typically has 150–200 calories, depending on flavor and fat/sugar content.
Are muffins ok for weight loss?
Yes—in moderation. Choose small/mini or homemade whole‑grain versions and log them into your daily calorie target. The main risk is large café muffins (400–700+ kcal) or eating several minis without noticing.
What is a serving size of mini muffins?
Nutrition panels usually define 1 mini muffin as a serving (~15–25 g), but snack pouches often contain 4 minis (~180–220 kcal) and are treated as one serving in practice.
How many calories in a Costco bakery muffin?
Current estimates put regular Costco bakery muffins at about 410–460 calories each, with some flavors historically higher. Costco “small” muffins are likely ~200–250+ calories per piece.
Conclusion & next steps
Small and mini muffins sit in the 60–200 kcal range per piece, but portion size—and brand—makes all the difference. Instead of swearing them off, treat muffins as a planned treat: check labels when possible, assume higher numbers for chocolate and Costco‑style bakery items, and balance them with lighter meals. If you’re counting calories or managing weight, consider logging a realistic serving (2–3 minis or one small muffin) and pairing it with protein (like yogurt or nuts) to stay full.
