Preheat oven to 350°. Line a muffin tin with cupcake liners. Set aside.
Using a potato masher or mortar, grind the dehydrated strawberries to a powder (some tiny pieces are fine). If you're going to make the frosting, pulverize the 1/2 cup dehydrated strawberries needed for that along with this cup to save time. Set aside. *See note
In a large bowl, cream the butter and sugar together on high until pale and fluffy (3-4 minutes). Mix in the eggs and vanilla until combined.
In a medium bowl, combine all dry ingredients. In batches alternating between dry ingredients and buttermilk, add in the rest of the ingredients and mix until just combined (overmixing will result in a less tender cupcake).
Scoop batter into cupcake molds until about 2/3 full. Bake in oven for 18-19 minutes (you can test doneness by inserting a toothpick into the middle of a cupcake, which should come out clean if done). Let cool for 5 minutes then carefully remove cupcakes onto a cooling rack to cool completely.
Strawberry Cream Cheese Frosting
In a large bowl, mix the butter and cream cheese on medium-high until fluffy and incorporated. Add in the vanilla, powdered sugar and dehydrated strawberries. Mix until combined .
Assembly
Take a piping bag or offset spatula and spread the frosting on each cupcake. Enjoy!
Notes
*I like to put the strawberries in a small ziplock bag for easy clean up
