Preheat your oven to 350°F. This ensures that the Fresh Blueberry and Cherry Cake Bars will bake evenly.
In a medium saucepan, melt the butter and sugar together over medium heat, stirring continuously until smooth.
Remove from heat, stir in the vanilla extract and let cool for a few minutes.
In a large mixing bowl, combine the butter mixture with the eggs, whisking until fully blended.
Sift together the flour, baking powder, salt, and cinnamon before blending into the wet mixture until combined.
Fold in the fresh blueberries and cherries gently into the batter.
Transfer the batter into the prepared pan and smooth the top.
Bake for 40 to 50 minutes until golden brown, then allow to cool before slicing.
Slice into bars and enjoy!
