Spray four mini loaf pans with non-stick baking spray, line them with parchment, and spray the parchment.
Mix flours, salt, baking powder, and baking soda.
Cut butter into the flour mixture with a pastry cutter until the mixture resembles coarse crumbs.
Add the seeds to the flour/butter mixture and stir well to distribute them.
In a separate bowl, whisk together the eggs, yogurt, milk, and honey.
Make a well in the center of the flour mixture, pour in the yogurt mixture; stir well to combine (batter will be sticky).
Spoon the batter into the pans, smoothing the tops; evenly distribute the mixed topping seeds on top of the batter.
Set the pans on a larger baking sheet, and bake until the loaves are slightly cracked and golden brown, about 1 hour. (A toothpick inserted into centers should come out clean.)
Let the bread cool in the pans set on a cooling rack for 15 minutes, then turn out onto the rack and cool completely.
