Trail Mix Blondies are easy, sweet, shareable bars with your favorite snack-mix toppings mixed all throughout. Great for parties or lunches!
Blondies are a classic Bar Recipe. They’re similar to Brownies, but instead of a chocolate flavor from cocoa powder, they have vanilla. The simple, buttery, vanilla base makes it perfect for delicious mix-ins just like in this trail mix version.

Chef’s Note
You can enjoy delicious Trail Mix Bars any time of year, but they’re especially great to make during the summer. That’s the time of year most people are eating snack mixes, and it’s a fun way to change up a classic snack. The protein in the peanuts also makes them a great treat to give your family lots of energy for whatever outdoor activities you’re up to.
How to Store
- Serve: Let the Trail Mix Blondies cool to room temperature before you slice them into squares. Once they’re cooled, you can cover them in plastic wrap or transfer them to an airtight container to store at room temperature for 1 week.
- Store: You could also refrigerate the Trail Mix Bars for up to 2 weeks.
- Freeze: To keep the blondies for up to 4 months, keep them sealed in the freezer. Put them in a freezer bag or another airtight container with the layers separated by parchment paper so that they don’t stick together.
Variations
- Mix-ins: You can add various ingredients to this recipe for a unique twist. Add any of your favorite treats that you would typically use in a snack mix. Pumpkin seeds, walnuts, pecans, coconut flakes, or dried cranberries would all taste great. You can also change up the chocolate chips in the recipe with white chocolate chips, milk chocolate chips, or peanut butter chips.
- Flour: For a healthier take on blondies, you can use whole wheat flour instead of all-purpose flour.
- Sweeteners: You can also try different kinds of sweeteners. Instead of brown sugar, maple syrup, molasses, or coconut sugar could all make good replacements.

What size pan can be substituted for 8X10? I have a variety of baking pans, but none of that size. How deep should the pan be?
I am so sorry, I am just seeing this tonight. I am sure the recipe has long been cooked/or not but I still want to try to help.
9×9 would work just as well.
