This Prospectus Supplement (this “prospectus supplement”), amends and supplements our at-the-market offering prospectus dated December 20, 2024 (the “at-the-market offering prospectus”). This prospectus supplement should be read in conjunction with the at-the-market offering prospectus dated December 20, 2024, which is to be delivered with this prospectus supplement. This prospectus supplement amends and supplements only those sections of the at-the-market offering prospectus listed in this prospectus supplement; all other sections of the at-the-market offering prospectus remain as is.

BT Brands, Inc. (“we,” “us,” “our” or the “Company”) entered into an Equity Distribution Agreement with Maxim Group LLC (“Maxim”) dated December 13, 2024 (the “Original EDA”), relating to the sale of our common stock offered by the at-the-market offering prospectus. On November 21, 2025, we amended the Original EDA (as amended, the “Equity Distribution Agreement”) to, among other things, increase the maximum amount of shares of our common stock that we may offer and sell under the Equity Distribution Agreement from $3,005,000 to $3,565,880 from time to time through Maxim, acting as agent; provided, however, that in no event will we issue or sell through Maxim such number of shares of common stock that would cause us or the offering of the shares of common stock to not satisfy the eligibility and transaction requirements for use of Form S-3 (including General Instruction I.B.6 of Form S-3). As of December 1, 2025, we have not sold any shares of our common stock pursuant to the Equity Distribution Agreement.

Maxim will be entitled to compensation at a fixed commission rate of 3.0% of the gross proceeds of each sale of shares of our common stock. See “Plan of Distribution” beginning on page S-9 for additional information regarding the compensation to be paid to Maxim. In connection with the sale of shares of our common stock on our behalf, Maxim will be deemed to be an “underwriter” within
