Ingredient Overview

These chocolate chip banana bars are a warm hug in snack form—lightly sweet, soft, and studded with melty chocolate chips. Each bite feels like a reward, making them a go-to for your back-to-school snack game.

• Bananas: Overripe is best! They add moisture and natural sweetness while making the bars extra tender.

• Butter: Softened butter brings richness and that irresistible bakery-style texture.

• Brown Sugar & Granulated Sugar: A duo that deepens the flavor and helps create chewy edges.

• Vanilla Greek Yogurt: Adds a subtle tang and creamy body. Plain works fine too.

• Egg: Just one, but it helps bind everything together perfectly.

• Baking Powder & Salt: To give the bars lift and balance out the sweetness.

• All-Purpose Flour: Keeps the texture light and soft without making them cakey.

• Milk Chocolate Chips: Sweet, creamy, and kid-approved. Sprinkle a few extra on top for that classic coffeehouse look.

Quick tip: Spray the back of a spoon with cooking spray to smooth the batter into your pan with ease—it makes cleanup a breeze too.

Step-by-step Instructions

Step 1: Preheat and Prep Your Pan

Start by preheating your oven to 350°F. Line a 9×9-inch baking dish with parchment paper or lightly coat it with cooking spray. This makes it easy to lift out the bars and keeps cleanup simple—ideal for busy mornings and batch-making school snacks.

Step 2: Cream the Wet Ingredients

In a mixing bowl, add the softened butter, granulated sugar, brown sugar, Greek yogurt, baking powder, and salt. Use a hand mixer or stand mixer and beat on medium speed for about 2 minutes. The mixture may look curdled at first—don’t worry, that’s totally normal. Keep going until it becomes smooth and creamy.

Step 3: Add Egg, Banana & Vanilla

Crack in the egg, pour in the vanilla extract, and stir in the mashed bananas. Beat again until everything is evenly combined. This is where those ripe bananas begin to shine, adding moisture and natural sweetness to your school snacks.

Step 4: Mix in the Flour and Chocolate Chips

Reduce your mixer to low and gradually add in the flour. Once the flour disappears, stir in the chocolate chips. The batter will be thick—think banana bread meets cookie dough. You can add a handful of mini chips on top for that bakery-style finish.
Tip: Fold gently to avoid overmixing and keep the bars soft and tender.

Step 5: Spread and Bake

Scoop the batter into your prepared baking dish. Drop spoonfuls all around, then spread it out evenly with the back of a greased spoon or spatula. Bake for 22–30 minutes. The bars should puff up, pull slightly away from the sides, and a toothpick in the center should come out clean or with a few moist crumbs.

Step 6: Cool and Slice

Let the bars cool in the pan for about 1 hour. This helps them firm up and slice cleanly—important for packing neat little squares of school snacks into lunchboxes. If you’re impatient (like me), go ahead and enjoy one warm with melty chocolate chips!

Now that your dish is coming together beautifully, let’s explore some pro tips and creative variations!

Pro Tips

For the best school snacks texture, make sure your bananas are extra ripe—those with deep brown spots on the peel work magic in baked goods. They mash smoother and create natural sweetness without needing extra sugar.

Spray your spoon or spatula with nonstick spray before spreading the batter into the pan. It’ll prevent sticking and make smoothing it into the corners much easier. I do this every time I make treats like these or even when prepping my favorite after school snacks.

Use parchment paper to line your pan for the cleanest, most even slices. You can lift the entire batch out in one piece and cut tidy squares without losing a single crumb—essential when prepping multiple school snacks for the week.

Store your cooled bars in an airtight container at room temperature for up to 3 days, or freeze them in a single layer for up to 2 months. They thaw beautifully in lunchboxes by lunchtime—soft, sweet, and just as satisfying.

Want a little extra nutrition? Mix in a tablespoon of ground flaxseed or chia seeds. The kids won’t even notice, and it adds a gentle boost to their mid-morning school snacks.

Variations

Swap the chocolate chips with mini M&M’s or colorful sprinkles for a fun twist your kids will beg for again and again. These treats turn into cheerful school snacks worthy of a bake sale or class party.

Make them gluten-free by using a 1:1 gluten-free flour blend. I’ve tested it with great results—it still bakes up soft and golden. You can even check out our healthy school snacks roundup for more allergy-friendly ideas.

Try nutty add-ins like chopped walnuts or pecans if your school allows them. They bring a lovely crunch and pair beautifully with banana. Otherwise, pumpkin seeds or sunflower seeds are great nut-free options.

You can easily reduce the sugar slightly if your bananas are super sweet. I’ve made these with just ¼ cup brown sugar and ¼ cup white sugar and still got thumbs-up all around at our playdate picnic.

Want more fruit? Toss in a handful of dried cranberries or raisins for a touch of tartness. It turns everyday school snacks into a fruity surprise that’s still perfectly sweet.
