AN EASY HOMEMADE BLONDIE RECIPE

The only difference between a blondie and a brownie is that brownies have cocoa powder added. I love experimenting with blondies because you can add so many different flavors and, in a blondie, you can really taste those different add-ins. If you love the taste of butter rum LifeSavers then you’ll love these blondies!

TIPS FOR MAKING BLONDIES:

  • If you don’t like rum extract, just leave it out.
  • You can find the toffee baking bits where the chocolate chips are in your grocery store.
  • The flaked sea salt topping is optional in this but I really love the contrast of flavor it adds against the sweet blondies.
  • After making these, I realized that lining the baking dish with parchment paper would’ve made for easier removal and slicing. So if you have parchment paper, I definitely recommend using it instead of just baking spray.

  1. If I half this recipe would I bake it in an 8 x 8 for the same amount of time?
    I like my brownies/blondies a little on the underdone side and since my oven runs hot would I be safe with maybe 23 minutes or with a few moist crumbs on a toothpick?
    And lastly, could I add extra vanilla in place of the rum?
    Thank you so much for answering this new (but old!) baker.
