  1. Heat the oven to 325°F. Pan spray a 8x8” square baking dish.

Mix in egg and clear vanilla extract and stir until well combined, scraping down the sides of the bowl as you go. Add in flour and salt and mix just until combined.


  1. Spread the blondie batter evenly across the surface of the greased baking dish. Scatter the sprinkles, unbaked bday crumbs and any additional bday energy over the surface of the blondie. With a butter knife, s wirl into the batter into and over or leave as a topping.


  1. Bake at 325°F for 45 minutes until the edges are golden brown and the bullseye center is set.


  1. Cool completely at room temperature in the pan. Cut into 3 rows of 3 squares. Store in an airtight container or plastic wrapped on the counter for up to 5 days or in the fridge for up to 2 weeks.
