I’ve been enjoying oatmeal bars as my afternoon snack lately. I’ve seen lots of different variants on the idea, so my guess is you can adjust this quite a bit to your preferences. Here’s a good starting point, with a balance of macros and a nice, cakey texture.
Banana Peanut Butter Oatmeal Protein Bars
one. Whisk together the dry ingredients:
1 1/2 cups quick oats
1 cup whole wheat flour
1/2 cup granulated sugar
3 scoops whey protein powder(1)
1/4 cup brown sugar
3 Tbs. ground flaxseed
1 Tbs. baking powder
1 tsp. baking soda
1 tsp. cinnamon
1/2 tsp. salt
two. In another bowl, whisk together the wet ingredients:
3/4 cup nonfat Greek yogurt
1/2 cup liquid egg whites
2 Tbs. canola
1 tsp. vanilla extract
6 tsp. crunchy natural peanut butter, warmed until liquid
2 overripe bananas, roughly chopped
three. Stir the wet and dry ingredients together just until combined.
four. Pour into a large (mine is bigger than 9×13, maybe 10×15 or so?), lightly greased baking pan and spread evenly. Bake until firm in the center, about 25-30 min.
Yields 6 large “meal” size servings, or 8 or more smaller snack servings. This freezes and thaws well, if you need to store some for longer than a few days.

(1) I have used both sweetened, flavored whey isolate and unflavored. Both work fine, as long as the flavoring blends with banana and peanut butter ok. Of course, it makes a sweeter final product to use a sweetened protein powder, which may or may not be a bonus in your book. I haven’t tried other kinds of protein powder, so I can’t say how well it might work with other types.
