- 1 cup rolled oats - 1 cup all-purpose flour - 1/2 cup brown sugar - 1/2 cup unsalted butter, melted The base of these bars is simple. Rolled oats give a chewy texture. All-purpose flour binds everything. Brown sugar adds a nice touch of sweetness. Unsalted butter brings richness and helps form that lovely crumble. - 1 cup mixed berries (blueberries, raspberries, strawberries) - 1 tablespoon lemon juice - 1 tablespoon cornstarch The berries shine in this recipe. I like using a mix of blueberries, raspberries, and strawberries. They bring bright flavors and colors. Lemon juice adds a zest that brightens the berry taste. Cornstarch thickens the berry filling so it holds together. - 1 tablespoon honey or maple syrup - 1/2 teaspoon baking powder - 1/2 teaspoon cinnamon - 1/4 teaspoon salt These optional ingredients can enhance the bars. Honey or maple syrup can add extra sweetness. Baking powder helps the crumble rise a bit. Cinnamon gives a warm flavor. A pinch of salt balances the sweetness. You can choose any of these to match your taste. 1. First, preheat your oven to 350°F (175°C). Line an 8x8-inch baking dish with parchment paper. Leave some paper hanging over the sides. This helps you lift the bars out after baking. 2. In a big bowl, mix together the rolled oats, all-purpose flour, brown sugar, and baking powder. 3. Add the melted butter, cinnamon, and salt. Stir until it looks crumbly. 1. In another bowl, toss your mixed berries with lemon juice and cornstarch. 2. If you want extra sweetness, add honey or maple syrup. Mix gently so the berries stay whole. 1. Press a little more than half of the crumble mixture into the bottom of your baking dish. This makes the crust. 2. Spread the berry mix evenly on top of the crust. 3. Next, sprinkle the leftover crumble mixture over the berries. 4. Bake everything for 25 to 30 minutes. The top should look golden and the berries should bubble up. 5. Once baked, let the bars cool in the pan for about 15 minutes. Lift them out using the parchment paper. Cool completely on a wire rack. Then cut into squares. Enjoy your Triple Berry Crumble Bars! To get the best crust, you want a crumbly texture. Mix your rolled oats, flour, brown sugar, melted butter, baking powder, cinnamon, and salt well. You should see little clumps, not a smooth batter. For baking time, remember to check your bars early. They should bake until the top is golden brown. This takes about 25 to 30 minutes. If they look too dark, take them out right away. These bars shine when served warm. Add a scoop of vanilla ice cream on top. The cold ice cream melts into the warm berries, creating a tasty mix. You can also serve them with whipped cream for extra creaminess. Pair these bars with a nice drink. A cup of tea or a cold glass of lemonade works well. Both drinks balance the sweet and tangy flavors of the berries. If you need a gluten-free option, use almond flour or gluten-free oats instead of regular flour. This change keeps the texture while making it safe for gluten-free diets. For sweetness, you can swap honey or maple syrup with agave nectar. This keeps the bars sweet without changing the flavor much. You can also skip the sweetener if you prefer less sugar. {{image_2}} You can use many types of berries in these bars. Seasonal berries like blackberries or cherries add a fun twist. You can mix fresh blueberries, raspberries, and strawberries for a classic taste. I love using whatever is ripe. If fresh berries aren't available, frozen berries work great too. Just thaw them first and drain any excess juice. This keeps your bars from being too soggy. Adding nuts can give your bars a nice crunch. Chopped almonds or walnuts work well. You might also stir in some seeds, like sunflower or flaxseeds, for extra nutrition. For warming spices, add a pinch of nutmeg or ginger. These flavors pair well with the sweetness of the berries and make each bite special. You can switch up the crust for new tastes. A graham cracker crust gives a sweet touch. Simply crush the crackers and mix them with melted butter. You can also try almond flour for a gluten-free base. If you want vegan options, use coconut oil instead of butter and a flax egg. This keeps your bars tasty and friendly for all diets. To keep your leftover bars fresh, store them in the fridge. Place them in an airtight container. They will last for about a week. If you want to store them longer, freezing is a great option. Wrap each bar in plastic wrap. Then, place them in a freezer-safe bag. These bars can stay fresh in the freezer for up to three months. To enjoy your bars warm, preheat your oven to 350°F (175°C). Place the bars on a baking sheet. Heat them for about 10 minutes. This keeps their crumbly texture and warms up the berries. If you like them cold, just take them out of the fridge and enjoy. Both ways are tasty, but warm bars are especially comforting! Yes, you can use frozen berries. They work well in these bars. Just toss them in the mixing bowl straight from the freezer. You may need to bake a little longer to get them bubbly. Frozen berries keep the flavor and make it easy to enjoy this treat year-round. To make these bars vegan, replace the butter with coconut oil or a vegan butter substitute. You can also use maple syrup instead of honey for sweetness. This keeps the dessert plant-based while still being tasty and satisfying. Use a sharp knife to cut the bars after they cool. A warm knife helps avoid crumbles. You can serve them plain or with a scoop of ice cream. They look lovely on a plate with fresh berries on the side. These bars can last for about five days in the fridge. Store them in an airtight container to keep them fresh. If you want them to last longer, you can freeze them for up to three months. Yes, you can double the recipe easily. Just use a larger baking dish, like a 9x13 inch. Keep an eye on the baking time, as it may need a few extra minutes. Enjoy making more to share with friends and family!

Ingredients
  

1 cup rolled oats

1 cup all-purpose flour

1/2 cup brown sugar

1/2 cup unsalted butter, melted

1/2 teaspoon baking powder

1/2 teaspoon cinnamon

1/4 teaspoon salt

1 cup mixed berries (blueberries, raspberries, strawberries)

1 tablespoon lemon juice

1 tablespoon cornstarch

1 tablespoon honey or maple syrup (optional for extra sweetness)

Instructions
 

Preheat your oven to 350°F (175°C) and line an 8x8-inch baking dish with parchment paper, leaving some overhang for easy removal.

    In a large mixing bowl, combine the rolled oats, all-purpose flour, brown sugar, melted butter, baking powder, cinnamon, and salt. Stir until the mixture is crumbly and well combined.

      Set aside a little over half of the crumble mixture (about 1 1/2 cups) for the topping and firmly press the remaining mixture into the bottom of the prepared baking dish to form the crust. Bake for 10 minutes.

        In another bowl, gently toss the mixed berries with lemon juice, cornstarch, and honey or maple syrup until the berries are coated.

          Remove the crust from the oven and evenly spread the berry mixture over it, followed by scattering the reserved crumble mixture on top.

            Return the bars to the oven and bake for an additional 25-30 minutes, or until the top is golden brown and the berries are bubbly.

              Allow the bars to cool in the pan for about 15 minutes before lifting them out using the parchment paper. Let them cool completely on a wire rack before cutting into squares.
