Chunky Monkey Protein Baked Oat Bars

Featured in: Everyday Bites

These wholesome banana-chocolate oat bars capture the essence of the classic Chunky Monkey smoothie bowl in a portable, bake-ahead format. Ripe mashed bananas provide natural sweetness and moisture while unsweetened applesauce keeps the bars tender without excess oil. Old-fashioned rolled oats form the hearty base, offering fiber and sustained energy.

The addition of vanilla or chocolate protein powder boosts each bar to 6 grams of protein, making them substantial enough for breakfast or post-workout fuel. Natural peanut butter contributes rich nutty flavor and healthy fats, while chopped walnuts add satisfying crunch and omega-3s. Dark chocolate chips provide indulgent pockets of bittersweet chocolate throughout.

Mixing the wet and dry ingredients separately ensures even distribution of flavors and textures. The bars bake at 350°F for 22-25 minutes until set and golden around the edges. Allow them to cool completely before slicing—this crucial step prevents crumbling and ensures clean, neat bars. They keep well at room temperature for three days or refrigerated for up to a week, making them excellent for meal prep.

Customize easily with pecans instead of walnuts, add chia or flax seeds for extra fiber, or use dairy-free chocolate chips for a vegan version. Each bar delivers 160 calories with 6 grams of protein in a handheld format that's perfect for busy mornings, afternoon snacks, or after the gym.

Zusatztipps für die Zubereitung

For best results, use very ripe bananas with plenty of brown spots - they'll provide natural sweetness and moisture. When mixing the batter, be gentle to avoid tough, dense bars. The mixture should be moist but not runny; if it seems too dry, add a splash more almond milk. Allow the bars to cool completely before cutting for clean, neat edges.

Varianten und Anpassungen

These versatile bars can be easily modified to suit your dietary needs. For a nut-free version, replace the peanut butter with sunflower seed butter and omit the walnuts or substitute with pumpkin seeds. Make them vegan by using maple syrup instead of honey and selecting a plant-based protein powder. For extra nutrition, fold in 2 tablespoons of chia or flax seeds. You can also swap the chocolate chips for dried cherries or blueberries for a different twist.

Serviervorschläge

Enjoy these bars at room temperature for a quick breakfast on the go, or warm them slightly and top with a dollop of Greek yogurt for a more substantial morning meal. They make an excellent pre-workout snack or post-exercise recovery food. For a special treat, drizzle with a little extra melted dark chocolate. Pair with fresh fruit and a glass of almond milk for a complete, balanced breakfast.

Recipe Guide

Can I make these bars vegan?

Yes, use maple syrup instead of honey and choose a plant-based vanilla or chocolate protein powder. Swap dark chocolate chips for certified dairy-free ones. The applesauce and mashed bananas provide excellent moisture without any animal products.

Can I use quick oats instead of old-fashioned rolled oats?

Old-fashioned rolled oats work best because they provide more texture and hold their shape during baking. Quick oats will make the bars softer and potentially mushy. If you only have quick oats, reduce the almond milk by 1 tablespoon to help maintain structure.

How do I know when the bars are fully baked?

The bars are done when the edges are golden brown and the center feels set when gently pressed. A toothpick inserted in the center should come out mostly clean with just a few moist crumbs. They'll continue to firm up as they cool, so don't overbake.

Can I freeze these baked oat bars?

Absolutely. Wrap individual bars in plastic wrap and place in a freezer-safe container for up to 3 months. Thaw overnight in the refrigerator or at room temperature for about an hour. They're excellent for grab-and-go breakfasts straight from the freezer.

What can I substitute for the protein powder?

If you don't have protein powder, increase the oats by 1/4 cup and add 2 tablespoons of ground flaxseed or chia seeds. Alternatively, use 1/4 cup of almond flour or additional oat flour. The texture will be slightly different but still delicious.

Why must I cool the bars completely before slicing?

Warm bars are fragile and prone to crumbling. Cooling allows the oats to fully absorb moisture and the structure to set. Let them cool in the pan for at least an hour, or refrigerate for even cleaner slices. Patience yields perfect, neat bars.
