Preheat oven 350℉. Line an 8x8 baking pan with parchment paper and lightly grease, then set aside.
In a large bowl, combine oat flour, almond flour, chia seeds, baking powder, and salt.
Add in maple syrup, almond milk, vanilla, almond extract, and lemon zest, stirring until fully combined. Lastly, fold in strawberries.
Pour into prepared pan and bake for 40 minutes, or until fork inserted in the cake's middle comes out clean.
Cool completely before adding frosting!
