Grease a 10 x 10-inch baking pan/ casserole butter.
Break eggs into a large bowl with milk, sugar and cinnamon, whisk until well combined.
Add peanut butter and mix well.
Cut or bread slices into triangles and place as layers in the baking pan.
Pour milk mixture into over bread slices. Sprinkle raisins and little sugar.
Bake until the mixture is set, and the top is golden brown (for 25 minutes).
Make the pudding tastier by adding sliced banana and chocolate chips instead of raisins.
