A homogeneous sweetener composition containing aspartame (APM) and N-[N-(3,3-dimethylbutyl)-L-alpha-aspartyl]-L-phenylalanine methyl ester having tasting properties similar to sucrose, can be efficiently produced in high yields and with a high purity by reductive alkylation of APM with an at most equimolar amount 3,3-dimethylbutylaldehyde followed by separating the reducing agent from the liquid reaction mixture, and separating of the precipitated crystals of the sweetener composition.
