Step 1 Heat the oven to 375 degrees. Cream the butter and sugar until light and fluffy. Beat in the eggs and vanilla. Sift together the flour, baking powder and salt. Add to the butter mixture alternately with the milk, beginning and ending with dry ingredients.
Step 2 Fold in the 1 cup chopped macadamia nuts and the cubed guava paste, separating the pieces of guava paste (which tend to stick together) so they will be evenly dispersed in the bread.
Step 3Spoon the mixture into a buttered 9x5-inch loaf pan. Sprinkle the coarsely chopped macadamia nuts over the top. Bake 60 to 70 minutes or until the center tests done. Remove the bread from the oven and let it cool in the pan 10 minutes, then remove it from the pan and let it stand until warm on a wire rack.
Step 4To serve, top with the chilled, dressed tropical fruit salad.
