Instructions
Step 1
Preheat the oven to 350°F and line an 8x8 baking dish with parchment paper.
Step 2
In a microwave-safe bowl, combine the butter and sugar. Heat in 30-second increments, stirring each time, until melted and smooth.
Add the applesauce and flax seeds. Mix well and let cool slightly.

Add the dry ingredients to the cooled wet mixture and mix until fully combined.
Step 4
Pour the batter into the prepared baking dish and spread into an even layer.
Bake for 25–30 minutes, until the edges are golden brown and a toothpick inserted comes out clean.
Let cool completely.

Whisk together all frosting ingredients until smooth.
Spread evenly over the cooled oat base.
Step 6
Cut into squares and serve.
