Heaven Cakes!

Fat adds richness. If you use butter as the fat, it will add flavor. It also prevents gluten development which means that butter (or another fat) will prevent your cake from being chewy like bread (which has no fat).

Salt heightens the other flavors and should be used judiciously

Adding eggs does a few things. It is a binding ingredient that creates structure and it’s an emulsifier in that it prevents separation of ingredients that would normally separate (like water and oil).

Something tells me butter doesn’t belong in dog treat recipes. I’m not a dog treat expert, but it just doesn’t sound right. Eggs, yes, definitely. They’ll give your dog a shiny coat.

Here’s a dog treat recipe I have personally, if you’d like it:

1/2 cup warm water (105 to 115 degrees)
1 package active dry yeast
1 teaspoon sugar
2 c all purpose flour
2 c whole wheat flour
2 c cornmeal
2 c old fashioned oats, uncooked
1 c chopped mint leaves
1 c chopped parsley
1/2 c toasted wheat germ
1 can (13 3/4 to 14 1/2 oz) beef broth
3/4 c milk

Preheat oven to 350 degrees F. In small bowl, combine warm water, yeast, and sugar; let stand until yeast foams, about 5 minutes.
In a very large bowl, combine ingredients all purpose flour up through wheat germ. With wooden spoon, stir in yeast mixture, broth, and milk until combined. With hands, knead dough in bowl until blended, about 1 minute.
Divide dough in half. Cover 1 piece with plastic wrap to prevent from drying out. Place remaining dough on lightly floured surface. With floured rolling pin, roll rough 1/4 inch thick. With large (about 5 inches) or small (about 2 inches) cookie cutter, such as bone shape, cut out as many biscuits as possible; reserve trimmings. Transfer biscuits to ungreased cookie sheet. Reroll trimmings and cut more biscuits. Repeat with remaining dough.
Bake small biscuits 30 minutes; large biscuits 40 minutes. Turn oven off, leave biscuits in oven 1 hour to dry out.
Transfer biscuits from cookie sheet to wire rack. When cool, store at room temperature in tight container up to 3 months.

Most things are for flavor. Salt can also be a slight leavening agent, as well as a preservative. Eggs can be a binding agent. It all depends on the recipe. A pet treat should have olive oil or hemp oil instead of butter. It should have minimal salt. Eggs are fine. Butter can make something crisper and flatter depending on how it was handled in the dough before baking – was it melted, was the dough chilled, was the butter creamed, etc. Sugars also help with crisping, but I would use honey and/or molasses instead of sugar in a critter treat, as well as whole meal flours/grains.
