Total Time 50 minutes


  • 1 cup flour
  • 1 cup used coffee grounds (I get them for free from Starbucks since I don't drink coffee)
  • 1/2 cup salt
  • 1/4 cup sand (You can use beach sand, playground sand, sand from Home Depot, or even cornmeal if you don't have any sand)
  • 3/4 cup water
  • Small toys and prizes (Marbles, plastic animals, fake or real coins, and plastic jewelry are all great choices!)


  • Preheat the oven to 175 degrees F. Combine all of the dry ingredients, then slowly add in the water and stir until the mixture becomes a dough. If the dough is still too wet, add some flour or sand to get the right consistency. The dough should be nice and firm, and not too wet.
  • Roll a piece of dough into a ball, add a toy or two to the middle, then roll the dough back into a nice, smooth ball.
  • Place the balls of dough on a foil-covered baking sheet, and bake for 45 minutes. Be sure to let them cool completely before letting kids break them open.
