Preheat the oven to 350°F. Line a 9x13" baking dish with parchment paper.
In a bowl, combine all of the ingredients for the bars and stir until evenly mixed. Pour into the prepared baking dish and use the back of a measuring cup to press the granola firmly down into an even layer.
Bake for 30 minutes or until golden brown. Let rest until completely cooled.
Berry Layer
Strain the liquid away from the thawed out berries and lightly smash them with a fork. Stir in the cinnamon, sugar, and lemon zest. Spread into an even layer on the granola bars.
Yogurt and Toppings
Pour the yogurt on top of the berry mixture and use a spoon to spread it around. Lightly press the fresh berries into the yogurt and sprinkle on the cranberry seeds.
Transfer the completed bars to the freezer for one hour. Use the parchment paper to remove the bars from the baking dish and use a knife to cut them into bars. Return to the freezer for at least 4 hours, then transfer to an airtight container for storage.
As you spread the yogurt, it may pull up some of the berry mixture. This won't impact anything, it'll just give it a nice flair of color.
Use a long knife like a slicer to cut the bars. This helps keep the granola bars intact since they won't need a sawing or chopping motion to cut.
Once completely frozen, transfer the bars into a ziptop bag or airtight container to prevent unnecessary freezer burn.
These greek yogurt bars will stay good in the freezer for up to three months.
How do you get breakfast bars to stick together?The brown sugar and honey work like glue to bind the bars together. For it to completely do the job though, it needs time to harden and cool. If you cut the bars too soon they will crumble.
How do you keep granola bars from falling apart?Don’t skip the step of using something to press the ingredients firmly down into the pan together. This helps remove air that may prevent the bars from binding and helps them stay together.
Why is the frozen yogurt so hard?For softer frozen greek yogurt bars, whipped cream or sugar needs added. The downside to this though is that the yogurt melts faster and becomes soft in your hands similar to ice cream.
