Preheat oven to 375 degrees F. In a large bowl, cream together butter and sugar until light and fluffy. Add eggs, one at a time, mixing after each egg. Mix in vanilla.
In a separate bowl, whisk together flour, salt, and baking soda. Add to wet mixture and mix until just combined.
Place small balls of dough into all 48 cups of a mini cupcake pan. Press each ball of dough lightly with the back of a teaspoon. Bake for 10-12 minutes, until light golden brown.
While the sugar cookie bites are cooking, add all the frosting ingredients except the heavy cream into a mixer. Mix well until combined. Slowly add the heavy cream while the mixer is running and continue to mix until stiff peaks form (about 2-3 minutes).
Place a dollup of frosting onto the top of each mini sugar cookie bite after they have cooled completely. Sprinkle with any toppings you desire.
Notes
This is the perfect dessert for a wedding reception, baby shower, holiday party or birthday. Add whatever toppings the occasion permits.
