Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	The Company operates and reports financial information on a 52 or 53-week year with the fiscal year ending on the Sunday closest to December 31. The data periods contained within fiscal years 2022 and 2023 will reflect the results of operations for the 52-week periods ended January 1, 2023 and December 31, 2023, respectively. The quarters ended October 1, 2023 and October 2, 2022 were both 13-week periods.The unaudited Condensed Consolidated Financial Statements include the accounts of KKI and subsidiaries and have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). Accordingly, these interim financial statements do not include all information and footnotes required under GAAP for complete financial statements. In the opinion of management, the accompanying unaudited Condensed Consolidated Financial Statements contain all adjustments, consisting of only normal recurring adjustments, necessary for a fair statement of results of operations, balance sheet, cash flows, and shareholders’ equity for the periods presented. All significant intercompany balances and transactions among KKI and subsidiaries have been eliminated in consolidation. Investments in entities over which the Company has the ability to exercise significant influence but which it does not control and whose financial statements are not otherwise required to be consolidated, are accounted for using the equity method.
Consolidation	These Condensed Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements and notes thereto as of and for the year ended January 1, 2023, included in the Annual Report on Form 10-K. The Condensed Consolidated Balance Sheet as of January 1, 2023 was derived from audited annual financial statements but does not contain all of the footnote disclosures from the annual financial statements. The results of operations for the quarter ended October 1, 2023 are not necessarily indicative of the results of operations that may be achieved for the entire fiscal year ending December 31, 2023. Noncontrolling interest in the Company’s Condensed Consolidated Financial Statements represents the interest in subsidiaries held by joint venture partners and employee shareholders. The joint venture partners hold noncontrolling interests in the Company’s consolidated subsidiaries, Awesome Doughnut, LLC (“Awesome Doughnut”), W.K.S. Krispy Kreme, LLC (“WKS Krispy Kreme”), and Krispy K Canada, Inc. (“KK Canada”). Employee shareholders hold noncontrolling interests in the consolidated subsidiaries Krispy Kreme Holding U.K. Ltd. (“KKUK”), Krispy Kreme Holdings Pty Ltd. (“KK Australia”), Krispy Kreme Mexico Holding S.A.P.I. de C.V. (“KK Mexico”), and Insomnia Cookies Holdings, LLC (“Insomnia Cookies”). Since the Company consolidates the financial statements of these subsidiaries, the noncontrolling owners’ share of each subsidiary’s net assets and results of operations are deducted and reported as noncontrolling interest on the Condensed Consolidated Balance Sheets and as net income attributable to noncontrolling interest in the Condensed Consolidated Statements of Operations and comprehensive income attributable to noncontrolling interest in the Condensed Consolidated Statements of Comprehensive Income/(Loss).
Reclassifications	Reclassifications Segment information is prepared on the same basis that the Company’s management reviews financial information for operational decision-making purposes. Effective January 2, 2023, the Company realigned its segment reporting structure such that the Company-owned Canada business has moved from the U.S. and Canada reportable operating segment to the Market Development reportable operating segment. As a result, the U.S. and Canada reportable operating segment has been renamed to the U.S. reportable operating segment. All segment information has been restated to be consistent with current presentation. Exiting the Branded Sweet Treats Business During the quarter ended April 2, 2023, the Company decided to exit its pre-packaged Branded Sweet Treats business due in part to its dilutive impact on profit margins, as well as to allow the Company to focus on its fresh doughnuts business. Refer to “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Significant Events and Transactions” included in Item 2 of Part I of this Quarterly Report on Form 10-Q for further information.

It was effective for all entities as of March 12, 2020 through December 31, 2022. A company may elect to apply the amendments for contract modifications as of any date from the beginning of an interim period that includes or is subsequent to March 12, 2020, or prospectively from a date within an interim period that includes or is subsequent to March 12, 2020, up to the date that the financial statements are available to be issued. In December 2022, the FASB issued ASU 2022-06, Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848, which provides optional guidance to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform by delaying the effective date of the guidance issued in ASU 2020-04 to December 31, 2024. As described in Note 9, Long-Term Debt, during the quarter ended April 2, 2023 the Company refinanced its debt with interest to be calculated prospectively with reference to the Secured Overnight Financing Rate (“SOFR”), and accordingly adopted this standard, which did not impact the financial statements presented herein. In September 2022, the FASB issued ASU 2022-04, Liabilities — Supplier Finance Programs (Subtopic 405-50): Disclosure of Supplier Finance Program Obligations, which requires certain disclosures be made by a buyer in a supplier finance program, including the key terms of the program and, for the obligations that the buyer has confirmed as valid to the finance provider, the amount outstanding that remains unpaid by the buyer as of the end of the fiscal period, a description of where those obligations are presented in the balance sheet, and a rollforward of those obligations during the fiscal period. It is effective for all entities for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years, except for the amendment on rollforward information, which is effective for fiscal years beginning after December 15, 2023. Early adoption is permitted. As such, the Company adopted this standard in the quarter ended April 2, 2023 and has disclosed the required information in Note 8, Vendor Finance Programs, other than the rollforward information which is not effective until fiscal years beginning after December 15, 2023. The Company is currently evaluating the effect of the new guidance on its annual disclosures.
