RED Velvet Cupcakes – no food coloring added

 

RED Velvet Cupcakes (makes 24) with no added food coloring

 

1 can of beets, drained and then pureed in a food processor with other ingredients

180 mL of buttermilk at room temperature (3/4 cup)

Lemon juice freshly squeezed from one lemon

10 mL of white vinegar (5% acetic acid CH3COOH) (2 teaspoons)

200 grams cake flour (2 cups of presifted – don’t pack down, better is you use a balance and just obtain the proper mass)

24 grams Dutched cocoa powder (45 mL or 3 tablespoons)

7 grams Double acting baking powder (use Rumsford for aluminum free) (1 ¼ teaspoon)

6 grams sodium chloride (5 mL or 1 teaspoon table salt)

3 grams sodium hydrogen carbonate (2.5 mL or 1/2 teaspoon baking soda)

170 grams of butter (3/4 cup = 1 ½ sticks) at room temperature (298 K)

350 grams sucrose (1 ¾ cup table sugar)

10 mL pure vanilla extract (2 teaspoons)

3 large eggs at room temperature

 

  1. Preheat your oven to 450 K (350° F) Line muffin pans with liners.
  2. Purée beets with buttermilk, lemon juice, and vinegar until smooth.
  3. Sift together ( 2 times) flour, cocoa, baking powder, salt and baking soda in a separate bowl. 4
  4. Using your mixer (I have a kitchenaid) beat the butter for 3 minutes until light and fluffy and then gradually add the sugar while beating. Scrape down the sides with a spatula and get everything incorporated.   Now add the vanilla and beat until smooth.
  5. Beat in the eggs, one at a time, beating 30 seconds after each addition and then stopping and scraping down the sides.
  6. Now add the flour mixture alternately with the liquid mixture to the butter mixture, gently stirring until all incorporated ending with a dry mixture addition.
  7. Pour into the muffin liners and bake at 350 F about 20-22 minutes until they spring back when touched. Cool and frost with your favorite frosting. I use a cream cheese/butter frosting.

Getting Ready for Mole Day????

I was just asked for my Grandma Button’s Molasses cookie recipe so I thought I would post it again.  I use it as a dimensional analysis exercise after serving these delicious cookies to my class on October 21 (yes, I changed Mole Day to October 21 to be more “metric friendly.”)  Here is the recipe.  I really make these cookies using a metric balance and obtaining the masses indicated.  I do use a metric “teaspoon” for the spices, sodium hydrogen carbonate, and sodium chloride, but I use my balance for everything else.
