When I first tried making these Chocolate Banana Hazelnut Snack Squares, I wasn't sure how the flavors would blend. But I was pleasantly surprised! The combination of ripe bananas and rich cocoa creates a fudgy base that's simply irresistible. I discovered that baking them for just the right amount of time gives them a slightly chewy texture that I absolutely adore.

Another tip I learned is to lightly toast the hazelnuts before adding them to the mixture. This enhances their flavor and adds a wonderful crunch that contrasts beautifully with the soft squares. Trust me, this little step makes a big difference!

Ingredient Insights

The blend of ripe bananas in this recipe not only provides natural sweetness but also acts as a binding agent, keeping the squares moist and chewy. Ripe bananas are crucial here; their natural sugars elevate the taste profile while making the final product healthier than traditional snack bars. For the best results, use bananas with plenty of brown spots for maximum flavor and moisture.

Cocoa powder is a key player in delivering that rich chocolate flavor we all crave. Opt for unsweetened cocoa powder to maintain control over sugar content. If you're feeling adventurous, try using dark cocoa powder for an even bolder taste that contrasts beautifully with the nutty hazelnuts and sweet bananas.

Baking Techniques

When mixing the ingredients, ensure that the mashed bananas are well integrated into the dry ingredients. This prevents any lumps of cocoa powder or oats and ensures a uniform texture throughout the squares. I recommend using a whisk to blend the banana and syrup together before adding dry items. This will help achieve a smoother batter that bakes evenly.

Keep an eye on the baking time; ovens can vary significantly. After the 20-minute mark, check for doneness by inserting a toothpick in the center. It should come out mostly clean, with just a few moist crumbs. If it comes out with wet batter, give it a few more minutes, but be cautious not to overbake, as that can lead to dry squares.

Ingredients

Gather the following ingredients to get started:

Ingredients

2 ripe bananas, mashed
1/2 cup cocoa powder
1 cup rolled oats
1/2 cup chopped hazelnuts
1/4 cup honey or maple syrup
1/4 cup dark chocolate chips
1/2 teaspoon baking powder
1/4 teaspoon salt

Ensure all ingredients are at room temperature for best results.

Instructions

Follow these easy steps to prepare your snack squares:

Preheat the oven

Preheat your oven to 350°F (175°C) and line an 8x8-inch baking dish with parchment paper.

Mix the ingredients

In a large mixing bowl, combine the mashed bananas, cocoa powder, oats, honey or maple syrup, baking powder, and salt. Stir until well mixed.

Add nuts and chocolate

Fold in the chopped hazelnuts and dark chocolate chips until evenly distributed.

Bake the mixture

Pour the mixture into the prepared baking dish and spread evenly. Bake for 20 minutes, or until set.

Cool and cut

Allow the squares to cool in the pan for 10 minutes before lifting them out using the parchment paper. Cut into squares and enjoy!

Store any leftovers in an airtight container at room temperature for up to four days.

Pro Tips

For added texture, feel free to mix in different nuts or seeds. You can also replace the honey with agave syrup for a vegan option.

Serving Suggestions

For a delightful twist, serve your chocolate banana hazelnut squares with a dollop of Greek yogurt on top, adding creaminess and extra protein. You can also sprinkle them with a touch of sea salt or drizzle with additional melted dark chocolate to enhance their flavor profile.

Consider pairing these squares with a hot cup of coffee or tea for a satisfying afternoon snack. The rich chocolate flavor beautifully complements a strong beverage, making it a perfect pick-me-up during the day.

Storage and Freezing Tips

To keep these squares fresh, store them in an airtight container at room temperature for up to three days. If you want to make a bigger batch, they freeze beautifully! Simply cut the squares into individual servings, layer them between sheets of parchment paper in a freezer-safe container, and they can last up to three months, retaining their moist texture when thawed.

When you're ready to enjoy a frozen square, simply let it thaw at room temperature for about 30 minutes, or pop it briefly in the microwave for a quick warm-up. Just be careful not to overheat, as the chocolate can become melty and gooey.
