Ingredients

Scale 1x2x3x

1/2 cup (1 stick) unsalted butter, softened

3/4 cup granulated sugar

1 large egg

1 teaspoon vanilla extract

1/2 cup unfed sourdough starter discard (100% hydration)

1/2 teaspoon baking soda

1/4 teaspoon salt

1/2 cup rainbow sprinkles, plus extra for topping

---

Instructions

1. Preheat your oven to 350 F (175 C). Lightly grease and flour an 8×8 inch baking pan, or line it with parchment paper, leaving an overhang on the sides to easily lift the bars out later.

2. In a large mixing bowl, cream together the softened butter and granulated sugar using an electric mixer on medium speed until the mixture is light and fluffy, about 2-3 minutes.

3. Beat in the egg and vanilla extract until well combined. Then, add the sourdough starter discard and mix until just incorporated.

4. In a separate medium bowl, whisk together the all-purpose flour, baking soda, and salt.

5. Gradually add the dry ingredient mixture to the wet ingredients, mixing on low speed until just combined. Do not overmix.

6. Gently fold in the 1/2 cup of rainbow sprinkles with a spatula until they are evenly distributed throughout the dough.

7. Press the dough evenly into the prepared 8×8 inch baking pan. Sprinkle a few extra rainbow sprinkles over the top. Bake for 20-25 minutes, or until the edges are lightly golden and a toothpick inserted into the center comes out with moist crumbs. The center should look set.

8. Let the bars cool completely in the pan on a wire rack before slicing. Once cooled, lift them out using the parchment paper overhang and slice into squares.

Everything You Need To Make This Recipe Without Stress

Gathering your ingredients for these funfetti bars is straightforward, using common pantry staples. The star of the show, of course, is your sourdough discard, which adds a wonderful tang and chewiness without requiring any active fermentation.

INGREDIENTS:

• 1/2 cup (1 stick) unsalted butter, softened
• 3/4 cup granulated sugar
• 1 large egg
• 1 teaspoon vanilla extract
• 1/2 cup unfed sourdough starter discard (100% hydration)
• 1 1/2 cups all-purpose flour
• 1/2 teaspoon baking soda
• 1/4 teaspoon salt
• 1/2 cup rainbow sprinkles, plus extra for topping

For simple substitutions, feel free to use salted butter if that’s what you have on hand, just reduce the added salt to 1/8 teaspoon. If you don’t have vanilla extract, almond extract can offer a different but equally delicious flavor profile. Any brand of all-purpose flour will work beautifully here. The key is to use unfed sourdough discard, meaning it hasn’t been fed recently and isn’t actively bubbling. This ensures it acts more as a liquid and flavor enhancer rather than a leavening agent in this specific recipe.

How To Make It Step By Step With Visual Cues

Making these funfetti sourdough snack bars is a breeze. Follow these simple steps for perfect results every time.

1. Prepare Your Baking Pan: Preheat your oven to 350°F (175°C). Lightly grease and flour an 8×8 inch baking pan, or line it with parchment paper, leaving an overhang on the sides to easily lift the bars out later. This prevents sticking and makes cleanup a snap.
2. Cream Butter and Sugar: In a large mixing bowl, cream together the softened butter and granulated sugar using an electric mixer on medium speed until the mixture is light and fluffy. This usually takes about 2-3 minutes and ensures a tender crumb.
3. Incorporate Wet Ingredients: Beat in the egg and vanilla extract until well combined. Then, add the sourdough starter discard and mix until just incorporated. The mixture might look a little curdled at this stage, but don’t worry, it will come together.
4. Combine Dry Ingredients: In a separate medium bowl, whisk together the all-purpose flour, baking soda, and salt. This step helps distribute the leavening agents evenly throughout the dough.
5. Combine Wet and Dry: Gradually add the dry ingredient mixture to the wet ingredients, mixing on low speed until just combined. Be careful not to overmix, as this can lead to tough bars. A few streaks of flour are okay.
6. Fold in Sprinkles: Gently fold in the 1/2 cup of rainbow sprinkles with a spatula until they are evenly distributed throughout the dough.
7. Bake the Bars: Press the dough evenly into the prepared 8×8 inch baking pan. Sprinkle a few extra rainbow sprinkles over the top for a vibrant finish. Bake for 20-25 minutes, or until the edges are lightly golden and a toothpick inserted into the center comes out with moist crumbs, but not wet batter. The center should look set.
8. Cool and Slice: Let the bars cool completely in the pan on a wire rack before slicing. This is crucial for clean cuts and to allow the bars to set properly. Once cooled, lift them out using the parchment paper overhang and slice into squares.

Easy Variations And Serving Ideas That Fit Real Life

These funfetti sourdough snack bars are wonderfully versatile and can be adapted to suit various tastes and occasions. For a chocolate lover’s twist, swap out half of the rainbow sprinkles for mini chocolate chips. You could also add a teaspoon of lemon zest to the dough for a bright, citrusy flavor that pairs surprisingly well with the tang of the sourdough discard. For a more sophisticated touch, consider using white chocolate chips instead of sprinkles, or adding a sprinkle of flaky sea salt on top before baking to enhance the sweetness.

These bars are perfect for packing into lunchboxes, serving at birthday parties, or bringing to a casual get-together. They’re sturdy enough for transport and don’t require refrigeration. For a fun dessert, serve them slightly warm with a scoop of vanilla ice cream, or drizzle them with a simple glaze made from powdered sugar and milk. They also make a fantastic addition to a dessert platter alongside other cookies and brownies. Kids will especially love them as an after-school treat, and you can even involve them in folding in the sprinkles for an extra fun baking experience.

Common Slip-Ups And How To Avoid Them

Even simple recipes can have a few pitfalls. Here are some common mistakes and how to steer clear of them for perfect funfetti bars every time:

• Overmixing the Dough: This is a classic mistake that can lead to tough, dense bars. Once you add the dry ingredients to the wet, mix only until the flour streaks disappear. A few lumps are perfectly fine.
• Overbaking: Baking the bars for too long can result in dry, crumbly bars. Keep an eye on them, and remove them from the oven when the edges are just golden and the center looks set but still slightly soft. Remember, they will continue to cook slightly as they cool.
• Not Cooling Completely Before Slicing: It’s tempting to cut into these delicious bars right out of the oven, but doing so will result in messy, crumbly pieces. Allow them to cool completely in the pan. This gives them time to set up and makes for much cleaner slices.
• Using Active Sourdough Starter: This recipe specifically calls for *discard*, which is unfed and less active. Using a fed, active starter might alter the texture and rise of the bars, as it could introduce too much leavening.
• Forgetting to Grease and Flour the Pan: While parchment paper helps, a little grease and flour or cooking spray can be extra insurance against sticking, especially if you don’t have parchment with an overhang.

How To Store It And Make It Ahead Without Ruining Texture

These funfetti sourdough snack bars are wonderfully convenient for making ahead and storing.

Storing: Once completely cooled, store the bars in an airtight container at room temperature for up to 3-4 days. They tend to stay soft and chewy, and the flavors meld beautifully over time. If you live in a very humid climate, you might consider storing them in the refrigerator, but bring them back to room temperature before serving for the best texture.

Freezing: For longer storage, you can freeze these bars. Once cooled and sliced, place them in a single layer on a baking sheet and freeze until solid. Then, transfer the frozen bars to a freezer-safe airtight container or freezer bag, separating layers with parchment paper to prevent sticking. They can be frozen for up to 2-3 months. Thaw them at room temperature for a few hours before serving.

Make Ahead: You can prepare the dough up to 24 hours in advance. Simply mix the dough according to the recipe, cover the bowl tightly with plastic wrap, and refrigerate. When you’re ready to bake, let the dough sit at room temperature for about 15-20 minutes to soften slightly before pressing it into the pan and baking as directed. This is a great option for busy schedules!
