The approximate chemical composition and amino acid profile of Lupinus albus seeds were studied. Protein content of lupin and lupin mlik seeds; 45.2(±0.09) g/100g and 7.25(±0.08) g/100g, respectively; fat content 9.04(±0.14) g/100g and 6.01(±0.06) g/100g, respectively. Lupine seeds rich in leucine, lysine and proline: 4.168; 4.059 and 2.620 (g/100 g) respectively. This work made it possible, using the experimental design method, to carry out eighteen trials of dessert cream formulated with different concentrations of lupin milk. The reduction of the quantity of sucrose used to 7.15% instead of 11% and the use of 3.85% Stevia rebaudiana extract have resulted in a dessert cream that is lighter in sugar. The chemical properties of the formulated tests revealed a high protein content ranging from 8.36 to 16.25 g/100 g and a fat content ranging from 3.50 to 4.92 g/100 g. Finally an optimal formula was developed with good sensory characteristics.
