Peach Crumb Bar

One of the best things about summer is all of the fruits that are in season! And one of my favorite fruits of all? Peaches! Specifically white peaches. I love it when they’re crisp and crunchy, and when the flavor is light and sweet. And so before summer ends, I wanted to make this yummy treat to take advantage of the season and all the sweetness it has to offer.

The Ingredients

flour, sugar, peaches, butter, vanilla, egg, lemon juice, baking powder

For this recipe, the hero is, of course, the peaches. Because white peaches are my favorite fruit, I choose to make this crumb bar using white peaches, but they’re typically a lot more subtle in flavor compared to yellow peaches. So if you’re looking for a strong and tart peach flavor to come through, I’d suggest substituting the white for yellow.

I also used a combination of brown and granulated sugar for this recipe because I wanted the texture of the crumb crust to be a bit more chewier compared to a crust that might be more crispy if it were to be entirely granulated sugar. Feel free to play around with your sugar ratios to get the texture that you most prefer!

The Process

To start, I mixed together all the dry ingredients (flour, sugars, baking powder, salt, cinnamon).

Then I beat in the cubed butter, which was still cold. You can use a hand mixer or even a food processor and pulse it slowly until the butter makes the dry ingredients almost like clumpy sand. Then add in the egg and but until just combined.

To form the base, I pressed the crumb mixture onto the bottom of the baking dish that I coated with butter. This way it’ll be easier to remove from the pan after. Be sure to leave some crumb mixture so that it can be spread out on top afterwards.

Next up was the peach filling. I diced 2 white peaches, then coated them with sugar, cinnamon, and corn starch. The corn starch is what will help thicken the syrup-like coating that’ll form. Then I drizzled the lemon juice and tossed the peaches until it was evenly coated.

I spread the peach filling over the crumb base in the baking dish, then covered the top with the remaining crumb mixture, and then it was ready to head into the oven.

Baking time will vary based on how deep and large your baking dish is, but for mine I baked the rectangular glass baking dish for about 40 minutes and the round cake pan for about 45 minutes. I determined it was done based on the golden brown-ness of the top portion while also making sure that a toothpick through the center comes out clean.

Allow the baking dish to cool, then chill in the refrigerator for at least 30 minutes to an hour. I found that the crumb bars were much more fragrant after leaving them to chill in the refrigerator overnight, which allowed the flavor to really come out, but you can definitely have it ASAP!

The Results

I have to say this might be one of my favorite dessert treats so far! It was so easy to make, with super simple ingredients and pretty foolproof steps, and it was so nicely sweet and tasty!

The crumbliness of the crust was just right and very lightly sweet so that the flavor of the peach could really come through. As I mentioned before, white peaches have a much more subtle flavor, so this treat likewise has a very subtle sweetness and peach fragrance.

It tastes great chilled and even better warmed, so I’d highly suggest if you enjoy a warm treat to microwave it for a few seconds before enjoying.

ºoº Vegan replacements:

ºoº Resting the crumb bars overnight allows the flavor to really come through, so if you

can hold back, it’ll be worth the wait!

10 seconds or less
