Brownie Flag Recipe

Tomorrow is National Flag Day so I thought I would share this adorable Flag Brownie which not only is a great way to celebrate Flag Day but makes a fun 4th of July dessert.

I made a homemade brownie batter, but you could use a brownie mix. You would probably want to use 2 boxes of brownie mix.

My brownies were a little on the thin side and a boxed brownie would probably be even thinner if you only used 1 box.

Once baked and cooled, the brownie is covered with a thin layer of white frosting. I just used store-bought frosting but you could make your own. A cream cheese frosting would be really good.

The fresh blueberries and sliced strawberries are arranged to make a flag pattern.

Finally the space between the strawberry rows is filled in by piping rows of frosting using a pastry bag fitted with a large star tip.

The combination of chocolate, frosting, and fresh fruit makes a delicious and festive party dessert.

      I’m not exactly sure because I haven’t done it with 2 boxes but I would guess the proper cooking time would be between 40-50 minutes. I would give it a peek just shy of 40 minutes and go from there.

  2. This was a great first venture into baking and decorating. He really enjoyed the decorating part. Thanks for idea!

  3. If I doubled the batter and used the same pan for a thicker brownie, how long would I bake it for?

    Oh, gosh. I am SO making this for the 4th of July this year! I make something similar to this nearly every year, only mine uses yellow cake instead of brownies. So loving this twist! Pinned. ๐Ÿ™‚
