Item 1. Security and Issuer.

This Amendment No. 1 (this “Amendment”) relates to the Schedule 13D originally filed with the Securities and Exchange Commission on June 8, 2012 (as so amended, the “Schedule 13D”) by Burger King Holdings, Inc., a Delaware corporation (“BKH”), as the parent of Burger King Corporation, a Florida corporation (“BKC”), with respect to the common stock, par value $0.01 per share (the “Common Stock”), of Carrols Restaurant Group, Inc., a Delaware corporation (the “Issuer”), beneficially owned by BKC.

The principal executive offices of the Issuer are located at 968 James Street, Syracuse, New York 13203.

Item 2. Identity and Background.

Item 2 of the Schedule 13D is hereby amended and supplemented by the following information:

This Amendment is being filed by Restaurant Brands International Limited Partnership, a limited partnership organized under the laws of Ontario (“Partnership”), and Restaurant Brands International Inc., a Canadian corporation and the general partnership of Partnership (“RBI”, and together with Partnership, the “Reporting Persons”). The principal executive offices of each of the Reporting Persons are located at 130 King Street West, Suite 300, P.O. Box 399, Toronto, Ontario M5X 1E1.

Each of the Reporting Persons is an indirect holding company for The TDL Group Corp. and its consolidated subsidiaries, Burger King Worldwide, Inc. and its consolidated subsidiaries (including BKH and BKC), and Popeyes Louisiana Kitchen, Inc. (“Popeyes”) and its consolidated subsidiaries. RBI is one of the world’s largest quick service restaurant companies.

Partnership indirectly beneficially owns the shares of Common Stock directly beneficially owned by its wholly-owned subsidiaries. As the sole general partner of Partnership, RBI may also be deemed to indirectly beneficially own the shares of Common Stock beneficially owned by Partnership.

Set forth on Annex A to this Schedule 13D, and incorporated herein by reference, is a list of the respective executive officers, directors, control persons or general partner, as applicable, of the respective Reporting Persons that contains the following information with respect to each such person, as applicable: (a) name, (b) business address, (c) present principal occupation or employment (including the name and the principal business address, if other than the applicable Reporting Person, of any corporation or other organization in which such employment is conducted), and (d) citizenship.

During the last five years, neither of the Reporting Persons nor, to the best of their knowledge, any of their respective executive officers, directors, control persons or general partner, as applicable, (a) has been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors) or (b) was a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws.

Item 3. Source and Amount of Funds or Other Consideration.

Item 3 of the Schedule 13D is hereby amended and supplemented by the following information:

As previously reported, on March 26, 2012, the Issuer, Carrols LLC, an indirect wholly-owned subsidiary of the Issuer, and BKC entered into an Asset Purchase Agreement pursuant to which, on May 30, 2012, the Issuer issued 100 shares of Convertible Preferred Stock of the Issuer to BKC that was authorized pursuant to a Certificate of Designation filed with the Secretary of State of the State of Delaware on May 29, 2012.

SCHEDULE 13D/A

In order to provide transferability of the shares of preferred stock amongst the subsidiaries of the Partnership, BKC and the Issuer agreed to file a new Certificate of Designation creating a new series of Convertible Preferred Stock, par value $0.01 per share (the “Preferred Stock”) with the same, powers, preferences and rights of the prior shares of Preferred Stock, except that such shares are freely transferrable by BKC to any other person who is both (1) an affiliate of BKC and (2) a wholly-owned direct or indirect subsidiary of either RBI or Partnership (BKC and any authorized transferees, the “Investors”). There were no other material changes to the terms of the Preferred Stock.

Each share of Preferred Stock is convertible into 94,145.80 shares of Common Stock and votes with the Common Stock on an as-converted basis. Holders of the Preferred Stock are entitled to receive dividends payable on the Common Stock on an as converted basis, are entitled to a liquidation preference of $0.01 per share and thereafter will be entitled to share ratably (on an as-converted basis) with the Common Stock in the distribution of any remaining assets.

Upon exchange of the prior shares of Preferred Stock for the new shares of Preferred Stock, BKC effected an internal restructuring and transferred, for fair market value, 93 shares of Preferred Stock, representing the right to convert into 8,755,559 shares of Common Stock, to another indirect wholly-owned subsidiary of Partnership. The remaining 7 shares of Preferred Stock, representing the right to convert into 659,021 shares of Common Stock, continue to be beneficially held directly by BKC. Based on the ownership of the Preferred Stock by wholly-owned subsidiaries of Partnership, each of the Reporting Persons is deemed to beneficially own all 100 shares of Preferred Stock, representing the right to convert into 9,414,580 shares of Common Stock of the Issuer.

The foregoing summary of the Certificate of Designation is not intended to be complete and is qualified by reference to the copy of such document included as an exhibit to this Schedule 13D and incorporated herein by reference.

Item 4. Purpose of the Transaction.

The disclosures in Item 3 above are hereby incorporated by reference into this Item 4.

Item 4 of the Schedule 13D is hereby amended and supplemented by the following information:

(d) Pursuant to the Certificate of Designation, the Investors have the right to elect two members of the Issuer’s Board of Directors (the “Board”) as Class B Directors (as defined in the Certificate of Designation) until the date on which the number of shares of Common Stock into which the outstanding shares of Preferred Stock held by the Investors are then convertible constitutes less than 14.5% of the total number of outstanding shares of Common Stock (the “Director Step-Down Date”). From the Director Step-Down Date to the date on which the number of shares of Common Stock into which the outstanding shares of Preferred Stock held by the Investors are then convertible constitute less than 10% of the total number of outstanding shares of Common Stock, the Investors will have the right to elect one member to the Board as a Class B Director. The Class B Directors are a separate class of directors on the Board from the Class I, Class II and Class III directors of the Board. José E. Cil and Matthew Dunnigan, executive officers of the Reporting Persons, are the two directors designated by the Investors to serve as the Class B Directors of the Issuer.

The foregoing summary of the Certificate of Designation is not intended to be complete and is qualified by reference to the copy of such document included as an exhibit to this Schedule 13D and incorporated herein by reference.

Item 5. Interest in Securities of the Issuer.

(a) As the indirect parent of its indirect wholly-owned subsidiaries, as of the date of this Amendment, Partnership indirectly beneficially owns 9,414,580 shares of Common Stock which it has the right to acquire upon the conversion of shares of Preferred Stock of the Issuer. Such shares of Common Stock represent 20.5% of the outstanding Common Stock as of the date of this Amendment. As the sole general partner of Partnership, RBI may

SCHEDULE 13D/A

be deemed to indirectly beneficially own the shares of Common Stock directly beneficially owned by Partnership’s indirect wholly-owned subsidiaries. Except as set forth in this Amendment, neither the Reporting Persons nor, to the best of the knowledge of the Reporting Persons, any of the persons listed in Annex A beneficially own any shares of Common Stock or have any right to acquire any shares of Common Stock.

(b) As the indirect parent of its indirect wholly-owned subsidiaries, Partnership indirectly possesses sole voting and dispositive power over 9,414,580 shares of Common Stock. For the reasons described in paragraph (a) above, RBI may be deemed to indirectly possess sole voting and dispositive power over 9,414,580 shares of Common Stock.

(c) No transactions in the Common Stock have been effected by the Reporting Persons, or to the best of the knowledge of the Reporting Persons, any of the persons listed in Annex A, during the 60 days prior to the date of this Amendment.

(d) As the general partner of Partnership, RBI indirectly has the sole right to receive or the sole power to direct the receipt of dividends from, or the proceeds from the sale of, the shares of Common Stock described in paragraph (a) above.

(e) Not applicable.

Item 6. Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer.

Except as described in Items 3 and 4 of this Schedule 13D, there are no contracts, arrangements, understandings or relationships (legal or otherwise) among the persons named in Item 2, or any of the persons listed in Annex A, and between such persons and any person with respect to any securities of the Issuer, including but not limited to transfer or voting of any of the securities, finder’s fees, joint ventures, loan or option arrangements, puts or calls, guarantees of profits, division of profits or loss, or the giving or withholding of proxies.
