Back in my college classes, we students had opportunities to be food scientists and modify recipes.  Since we were also nutrition and dietetic students, we were told to focus these modifications on ways to add nutrition, such as adding fiber, or improve the nutritional profile, such as lower sodium.

Have you heard about replacing half of the fat in your cake recipe with applesauce before?  That's one popular example of food science in action.  And it lowers the amount of fat in the recipe, without significantly changing the taste, texture, or quality of the cake.  That's the goal - change it, but make sure anyone eating it does not notice the change.
 
Another modification for baking is using avocado!  The California Avocado Commission states that mashed avocado can replace butter or shortening in baked goods cup for cup.  So 1 cup of butter can be replaced with 1 cup of mashed avocado.
 
So, getting into food scientist-mode, I decided to replace the butter from my go-to brownie recipe with avocado. To see the original brownie recipe, go to the Applesauce:  Make It, Bake It, Eat It post.
 
While the recipe is below, I think you want to know how it tasted or smelled or looked before you make it!
 
  • Taste: To me, it tasted just like a yummy, chocolate brownie.  So gooey!
  • Smell: During baking, the brownie batter did smell like hot avocado.  (Go figure!)  It was an unusual smell, but not a bad one.  Once the brownies cooled, I did not notice that smell anymore; just chocolate.
  • Look: There are many brownie recipes that all look a little different.  This is no exception.  The original recipe has a drier, almost crackly top.  The modified recipe had a wetter-looking surface.
  • Nutrition: Since both avocado and butter are fat, the nutritional value of the recipe did not change much.  So why would I replace butter with avocado?  Avocados have mostly unsaturated or "liquid" fats, compared to butter that has saturated or "solid" fats.  Eating a diet with more unsaturated fats benefits heart health, such as improving blood cholesterol numbers.

1 medium avocado
1 (4-oz) single-serve cup or 1/2 cup unsweetened applesauce
1/2 cup cocoa powder
3/4 cup sugar
2 eggs
1/3 cup all-purpose flour
1/3 cup whole-wheat flour
1/4 tsp baking soda

1. Preheat oven to 350°F.
2. Wash avocado.  Run a knife around the pit, twist each side in opposite directions until they separate.  Remove pit carefully.  Scoop out avocado flesh into a medium bowl.  Mash with a fork, potato masher, or food processor until smooth.
3. Stir in applesauce, cocoa powder, sugar, and eggs.  Mix until smooth.
4. Stir in flours and baking soda until just moistened.
5. Pour into a greased 8 x 8-inch pan and bake for 35 minutes or until a toothpick inserted in the center is clean.  (Toothpick may have a few chocolaty crumbs sticking to it, but is still cooked.)
