Oatmeal to go bars (recipe)

I used to pack oatmeal to go bars in my lunch almost every day. That, a can of tuna, and some yogurt. Every day. 

I was really happy to figure out how to make a near copy. Luckily the icing on top makes Oliver love them. 

Preheat oven to 350. Line an 8x8" baking dish with foil. 

Mix wet ingredients: 1/2 cup almond milk, 1 egg, 3/4 cups brown sugar, 1 tsp vanilla

Mix dry ingredients: 1 3/4 cup oats, 1 cup whole wheat flour, 1/2 tsp baking soda, 1/2 tsp salt, 2 tsp cinnamon

Mix together. Press into dish. Bake for 20 minutes. 

Meanwhile, mix 2 T almond milk with 3T warm butter and stir in 1 cup icing sugar. If it's thin add milk, if it's thick add icing sugar. 

Let bars cool then drizzle with icing and cut.
