Margaret Bayne felt prompted to make vast quantities of the delicacy after learning of Elizabeth, a mother who had been squatting on a beach with her four children for five years.
The retired social worker raised £5,469 selling tablet to friends, acquaintances and members of the public in Perth and Dumfermline to meet the cost of constructing the home in Kikambala, Kilifi County.
Speaking on Premier's News Hour programme, Margaret said it was "so emotional" joining her husband, Bruce, on a visit to Kikambala and handing the keys to Elizabeth.
Margaret, who attends North Church in Perth, said the two-room home is being named 'Vanilla Cottage' to reflect the sweet essence she uses in making tablet, and cottage is a Scottish word.
Margaret said: "I knew that I could really make a difference to the lives of this family.
"I am a Christian and believe that God has plans for all of us, so I asked how much it would cost to build a house. And I said I could make tablet to finance it.
"But I was told I was mad and it could not be done but I was determined to help this poor woman and her children who were living on a beach 20 minutes away from the school with no shelter."
"I have a great faith and I just knew that, if God was calling me to help Elizabeth and her children in this way, I could do what I wanted to do.
"Going to Kenya was an amazing experience and I truly felt I was walking with God."
