Cookie, lemon bar calories: 166 per 1 medium bar (38 g)

This exact USDA record reports 166 calories for 1 medium bar (38 g). That answer belongs to this description and weight; it is not a universal value for every meal that shares the name.

The editorial read

The useful answer has a weight, a composition, and an identity

Portion: the cited record reports about 166 calories for 1 medium bar at 38 grams. On a fixed-weight basis, the same record contains 437 calories per 100 grams. The first number answers a portion question; the second answers a concentration question.

Composition: that source amount also reports 1.9 g protein, 0.3 g fiber, and 85 mg sodium. Read those values together: a calorie total by itself cannot describe the nutrient profile.

Identity: the largest listed formulation input is sugars, granulated, representing 32.1% of the record’s listed input weight. The record contains 8 source-input rows in all. These are provenance for a standardized calculation, not a recipe for your plate.

The source calls its underlying survey portion “Quantity not specified,” but it separately lists 1 medium bar at the identical weight. We use the familiar household label here without changing the source calculation.

The household measures attached to this record span roughly 109–245 calories across the listed portions. That is a set of scaled examples—not a confidence interval, a recommendation, or a claim about the full universe of recipes.

Calculated from the smallest and largest usable household measures listed by USDA for this exact FNDDS record; not a confidence interval.

Record-specific decision brief

What the numbers say—and what choice still belongs to you

This analysis belongs to USDA FDC 2707935: “Cookie, lemon bar.” It separates gram-weight arithmetic, corpus context, label signals, and record selection so one number does not have to answer four different questions.

01 · Portion arithmetic

Three weights, one fixed composition

For FDC 2707935, each row multiplies the published per-100-gram values by its stated weight. “1 small bar” through “1 large bar” are weight scenarios: named measures come from USDA, while percentage labels are transparent arithmetic.

02 · Fixed-weight context

Where 100 grams sits inside Cookies and brownies

The comparison set contains 83 exact records in the Cookies and brownies USDA category. Here, “middle half” describes FDC 2707935’s energy position in that corpus—not nutritional quality, desirability, or a health rating.

03 · FDA label lens

The strongest strength-side and tradeoff-side signals

At FDC 2707935’s 38 g reference weight, the largest strength-side percentage among the nutrients evaluated here is Vitamin A; the larger tradeoff-side percentage is Saturated fat. Percentages use FDA label Daily Values, whose general “high” guide begins at 20% Daily Value. This is not an overall score or a personalized target.

Strength-side signals

Vitamin A76.4 µg

≈ 8% DV. This does not cross the FDA’s 20% ‘high’ guide.

Tradeoff-side signals

Saturated fat1.4 g

≈ 7% DV. This does not cross the FDA’s 20% ‘high’ guide.

04 · Highest-impact checks

The three levers most worth resolving first

For “Cookie, lemon bar,” the first-pass checks follow the evidence actually published: its named weights, the FDC 2707908 alternative, and its source-formulation identity.

  1. 01

    Listed portion span: 1 small bar to 1 large bar

    USDA assigns those measures 25 g and 56 g. At this record’s fixed composition, scaled energy moves from 109 kcal to 245 kcal.

  2. 02

    Record choice: compare with FDC 2707908

    At an equal 100 g, this record has 1.2 g less dietary fiber than “Cookie, bar, with chocolate.” That is a record-level contrast; it does not identify which ingredient caused the difference.

  3. 03

    Formulation anchor: Sugars, granulated

    The source formulation has 8 input rows; Sugars, granulated supplies 32.1% of listed input weight. Those are standardized formulation inputs, not final plated percentages.

05 · Exact-record choice

Select by literal evidence, not the shortest name

Keep this record when “lemon bar” fits. Inspect FDC 2707908 when “bar; with chocolate” is the more literal description of the food and preparation.

Exact-record context

What makes this USDA record distinct?

For FDC 2707935, the close-record rule searches the USDA “Cookies and brownies” category for shared description terms or source inputs. Any surviving pair is compared per 100 grams, so unlike source-serving sizes cannot manufacture the nutrient difference.

Plain-English read

At the fixed 100-gram basis, this record lists 55 less calories, 5.8 g less total fat, and 1.2 g less dietary fiber than “Cookie, bar, with chocolate.”

Only this record lists Flour, wheat, all-purpose, enriched, bleached; Sugars, powdered; Margarine, stick; Eggs, Grade A, Large, egg whole. Only the comparison record lists Cookies, chocolate chip, commercially prepared, regular, higher fat, enriched. Those formulation rows identify different source records; they do not prove which input caused a nutrient difference.

4 of the six displayed differences clear the documented materiality screen. It is a reading aid, not a health rating.

Formulation evidence

The listed formulations differ

The formulation rows differ, but the source data do not isolate which component caused any nutrient difference. Input weights describe the standardized formulation—not final plated proportions.

Listed only in this record: Flour, wheat, all-purpose, enriched, bleached; Sugars, powdered; Margarine, stick; Eggs, Grade A, Large, egg whole; and 4 more.

Listed only in the comparison: Cookies, chocolate chip, commercially prepared, regular, higher fat, enriched.

Portion evidence

The listed portion sets differ

This record’s reference amount is 38 g; a familiar listed measure is 1 medium bar (38 g).

The comparison record’s reference amount is 50 g; a familiar listed measure is 1 medium (50 g).

Use the 100-gram row to compare FDC 2707935 with FDC 2707908 at equal mass; use their 38 g and 50 g source amounts only for portion matching.

Evidence boundary: FDC 2707935 versus FDC 2707908 is a comparison of standardized source records—not a measurement of your meal, an overall food-quality rank, or proof that one input caused a difference.

Uncertainty, made actionable

What can change this estimate?

This is a standardized USDA survey-food profile, not a measurement of every preparation. Actual nutrition can change with piece or portion size, recipe or brand, fillings or frosting, added fats and sugars.

For “Cookie, lemon bar,” resolve piece or portion size first, then move through the remaining 3 published levers. Unknowns should remain visible rather than expanding every assumption at once.

  1. 01

    piece or portion size

    When composition is held constant, nutrient totals scale directly with grams. A 20% weight correction produces the same 20% correction to the scaled totals.

  2. 02

    recipe or brand

    Prefer a package, menu, or known recipe when it identifies the food more precisely. Otherwise preserve the generic record as an explicit approximation.

  3. 03

    fillings or frosting

    Check whether the exact source description already includes it. If not, keep the addition separate rather than silently folding it into the base record.

  4. 04

    added fats and sugars

    Match the named cooking-fat state when possible. Fat used, retained, or left behind is preparation information that a dish name alone cannot recover.

How we estimated this

The arithmetic is simple; the provenance is the point

FDC 2707935 comes from FoodData Central Survey Foods (FNDDS). Its 437 kcal per 100 g becomes 166 kcal at 38 g through nutrient per portion = nutrient per 100 g × portion grams ÷ 100; this page adds no second nutrition estimate.

About the serving label: USDA describes the underlying survey portion as “Quantity not specified.” The separately listed 1 medium bar has the same gram weight, so the familiar label can be shown without changing the calculation.

Data cycle: 2021–2023, published October 31, 2024

FoodData Central ID: 2707935

FNDDS food code: 53224250

The scaling for FDC 2707935 can be exact while the match to “Cookie, lemon bar” is wrong. That is why this profile keeps its 38 g weight, 8-row source formulation, and selection uncertainty beside the arithmetic.
