Notes

⏲️ Storage

Blondies will dry out faster when they are cut. So, if you're making these ahead of time, I suggest not cutting them until the day of your party. These cake batter blondies are best when kept in an airtight container and eaten within the first 1-2 days. However, if they are uncut, you can stretch it to 3-4 days.

Alternatively, you can make these and freeze them. Wrap the whole block of blondies in plastic wrap, then slide them into a freezer bag (usually I cut the block in half so I have more manageable sections.) Label the bag and store in the freezer for up to 3 months.

📖 Variations

Holiday party? Baby shower? You can easily switch out the sprinkles to match any party theme or holiday. For example:

black and orange for Halloween
red, white and green for Christmastime
green and white for St. Patrick's day (perfect for your dessert table next to the Minty Shamrock CheeseBall)
pink and blue for a gender reveal party
red, white and blue for 4th of July, Memorial day or Labor day picnic
pink, purple and teal for a unicorn party (serve alongside this Unicorn Popcorn)
