Add all of the dry ingredients into the bowl EXCEPT the baking soda. Whisk it together. Add in the wet ingredients. Making sure that the butter is not hot, this could start to cook the eggs and kill your starter if it's hot.
Use either an electric hand mixer and mix for about 2 minutes or use a spoon and beat vigorously by hand for about 3 minutes.
At this point you can either add the baking soda and bake right away, or long ferment.
To long ferment cover with plastic wrap and place in the fridge for about 12 hours. When ready to bake, remove from the fridge and allow it to come to room temperature.
A quick way to do this is by placing in a warm oven that is turned off. While it is coming to room temperature, cut up your strawberries and create your macerated mix. Do this by chopping up your strawberries, adding the sugar and lemon juice and tossing together. Let this sit out while you bake the short cakes.
Preheat your oven to 350 degrees.
Spray the molds generously with cooking spray.
Add the baking soda to your batter and mix thoroughly. Scoop to fill each mold about 1/2-2/3 of the way full.
Bake the shortcakes for about 15 minutes. Set a timer for 12 minutes and check with a tooth pick. If the tooth pick comes out clean, they are ready. If not, bake it for the additional 3 minutes. Repeat this same process again at the end of the 3 minutes.
After they are done. Remove from the oven and allow them to cool until they can be handled comfortably without burning your hands.
Gently remove them from the molds. Top with the macerated strawberries and a dollop of whipped cream. Give homemade whipped topping a try! It's much easier than you might think!
