Ingredient Tips and Easy Substitutions
This recipe is flexible, but a few small choices can help you get the best results.
Can You Use Salted Butter?
Yes. If you use salted butter instead of unsalted, consider reducing the added salt slightly to keep the flavor balanced.
Can You Use Different Chocolate Chips?
Absolutely! White chocolate pairs especially well with vanilla, but you can substitute milk chocolate, semi-sweet chocolate, or a mixture of your favorites.
Keep in mind that different chocolates will change the overall sweetness and flavor.
Can You Replace the Sour Cream?
Full-fat plain Greek yogurt can work as a substitute for sour cream. It provides a similar tang and moisture, although the final texture may be slightly different.
Can You Use Different Candy Pieces?
Of course! M&M's are a fun choice, but you can also use other colorful candy-coated chocolates.
For the most attractive presentation, reserve a small handful of candies to press gently onto the surface before baking.
Can You Skip the Pudding Mix?
The instant vanilla pudding mix contributes flavor and affects the texture, so leaving it out may change the results. If you want to experiment without it, use a recipe specifically developed for that substitution rather than simply omitting the packet.
How to Make Holiday Dessert Bars
Ready to fill your kitchen with the smell of vanilla and freshly baked treats? Let's get started!
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C).
Lightly grease a 9x13-inch baking pan or line it with parchment paper, leaving a little overhang on the sides.
The overhang will help you lift the cooled bars out of the pan before slicing.
Step 2: Combine the Dry Ingredients
In a medium bowl, whisk together the flour, baking powder, salt, and instant vanilla pudding mix.
Mixing these ingredients first helps distribute the baking powder and pudding mix evenly throughout the flour.
Set the bowl aside.
Step 3: Cream the Butter and Sugar
In a large mixing bowl, beat the softened butter and granulated sugar until the mixture looks light and creamy.
This usually takes about 2–3 minutes with a hand mixer.
Scrape down the sides of the bowl as needed so everything combines evenly.
Step 4: Add the Eggs and Vanilla
Add the eggs one at a time, mixing after each addition.
Stir in the vanilla extract.
The mixture should look smooth and creamy. If it appears slightly curdled, don't worry too much; adding the dry ingredients gradually should help bring the batter together.
Step 5: Add the Sour Cream
Mix in the sour cream until it's evenly incorporated.
It adds moisture and a gentle tang that balances the sweetness of the sugar and candy pieces.
Step 6: Combine the Wet and Dry Ingredients
Gradually add the dry mixture to the wet ingredients.
Mix on low speed or fold with a spatula just until the flour disappears.
Avoid overmixing. Too much mixing after adding the flour can make the bars tougher instead of soft and tender.
Step 7: Fold in the Chocolate and Candy
Gently fold in the white chocolate chips and most of the colorful candy pieces.
Reserve a small handful for the top if you'd like a more festive finish.
The batter will be thick, so use a spatula to distribute the additions without overworking it.
Step 8: Spread the Batter in the Pan
Transfer the batter to the prepared baking pan.
Spread it evenly into the corners using a spatula.
Press the reserved candy pieces gently onto the surface. This helps create a colorful top that looks especially pretty once baked.
Step 9: Bake Until Set
Bake for approximately 25–35 minutes, checking toward the earlier end of the range.
The edges should look lightly golden, and the center should be set rather than wet or liquid.
A toothpick inserted into the center should come out without raw batter, although melted chocolate may leave a few moist crumbs.
Because oven temperatures and pans vary, use the appearance and doneness of the bars as your guide rather than relying on time alone.
Step 10: Cool Completely Before Slicing
Remove the pan from the oven and place it on a cooling rack.
Let the bars cool completely before lifting them out and cutting them into squares or rectangles.
I know it's tempting to cut into them while they're still warm, especially when the kitchen smells so good! But allowing them to cool helps them firm up and gives you cleaner slices.
Tips for the Best Holiday Dessert Bars
A few simple techniques can make a big difference.
Measure the Flour Carefully
Too much flour can leave the bars dry or dense. For the most consistent results, weigh the flour if you have a kitchen scale. Otherwise, spoon it into the measuring cup and level the top.
Use Room-Temperature Ingredients
Softened butter, eggs, and sour cream generally blend more smoothly when they aren't ice-cold.
This helps create a more uniform batter.
Don't Overmix
Once the flour goes in, mix only until the ingredients are combined. This helps preserve a tender texture.
Avoid Overbaking
Overbaking is one of the easiest ways to turn soft dessert bars dry.
Begin checking at around 25 minutes. Remove the pan when the center is set and a toothpick comes out without raw batter.
Let Them Cool Completely
Cooling makes the bars easier to slice and helps prevent the soft center from crumbling.
For especially neat squares, use a sharp knife and wipe the blade between cuts.
Make Them Extra Festive
Press a few additional candy pieces onto the top before baking, or sprinkle a small amount over the bars after they cool if you want a colorful finishing touch.
Fun Ways to Customize These Bars
The basic vanilla and white chocolate combination is delicious, but there are plenty of ways to change it up.
Christmas Dessert Bars
Use red and green candy pieces, then arrange the finished bars on a holiday platter with other Christmas cookies.
Halloween Dessert Bars
Choose orange, yellow, and black candy colors. Serve them alongside brownies and other Halloween treats.
Easter Dessert Bars
Pastel candies in pink, yellow, blue, and purple give these bars a soft springtime look.
Birthday Party Bars
Use rainbow-colored candies and cut the bars into small squares for a colorful dessert table.
Chocolate Lover's Version
Swap the white chocolate chips for semi-sweet chocolate chips or use a mixture of white and dark chocolate.
Nutty Vanilla Bars
If allergies aren't a concern, fold in about ½ cup of chopped pecans or walnuts for extra crunch.
What to Serve With Holiday Dessert Bars
These bars are delicious on their own, but they also pair beautifully with other treats and drinks.
Coffee or Tea
A cup of coffee or black tea balances the sweetness and makes these bars a lovely afternoon snack.
Hot Chocolate
For a cozy winter gathering, serve the bars with mugs of hot chocolate topped with whipped cream.
Vanilla Ice Cream
A small square of dessert bar alongside vanilla ice cream makes an easy plated dessert.
Fresh Fruit
Strawberries, raspberries, or sliced apples add a fresh contrast to the rich, sweet bars.
A Holiday Dessert Platter
Arrange the bars with brownies, sugar cookies, chocolate truffles, and other bite-sized treats for a colorful dessert spread.
Can You Make Holiday Dessert Bars Ahead of Time?
Yes! These bars are convenient to prepare ahead of a party or holiday gathering.
Bake them according to the instructions, allow them to cool completely, and store them in an airtight container.
For the best texture and flavor, make them a day ahead and slice them shortly before serving.
If you're preparing several desserts, you can bake these bars while other treats are cooling, then package them once they're completely at room temperature.
Avoid sealing them while warm, because trapped steam can make the surface damp.
How to Store Holiday Dessert Bars
Once completely cooled, place the bars in an airtight container.
They can generally be stored at room temperature for about 2–3 days in a cool environment, provided your kitchen isn't unusually warm and the ingredients have been handled safely.
For longer storage, refrigerate them and use within about 5–7 days for best quality.
If stacking the bars, place parchment paper between layers to help prevent sticking.
Before serving refrigerated bars, let them sit at room temperature briefly if you prefer a softer texture.
Can You Freeze Holiday Dessert Bars?
Yes! Freezing is a useful way to prepare for busy holiday weeks.
How to Freeze Baked Bars
Allow the bars to cool completely.
Cut them into individual portions or freeze them as one slab.
Wrap them tightly or place them in a freezer-safe container.
Separate layers with parchment paper if needed.
Label the container with the date.
For best quality, use frozen bars within about 2–3 months.
How to Thaw Frozen Bars
Transfer the bars to the refrigerator or let them thaw in their sealed container at room temperature.
Keep them covered while thawing to help prevent them from drying out.
Once thawed, serve them as they are or arrange them on a platter with your other holiday treats.
Frequently Asked Questions
Why are my holiday bars dry?
They may have been overbaked or made with too much flour. Measure carefully and begin checking for doneness at the earlier end of the baking time.
Why are the centers still soft?
The bars may need a little more time in the oven, especially if the pan is deep or the batter is particularly thick. The center should be set, not wet or liquid. Remember that the bars will firm up as they cool.
Can I use a different flavor of pudding mix?
You can experiment with other instant pudding flavors, but the taste and texture may change. Vanilla is the most straightforward choice for the classic flavor in this recipe.
Can I use a smaller baking pan?
A smaller pan will make the batter deeper and may require more baking time. Watch the center carefully and avoid removing the bars while the batter is still raw.
Can I double the recipe?
Yes, but use appropriately sized baking pans rather than making the batter excessively deep. Baking time will depend on the pan size and depth, so check each pan for doneness.
How do I get clean slices?
Let the bars cool completely, use a sharp knife, and wipe the blade between cuts. Chilling the bars briefly can also help if the center is especially soft.
Can I make these bars without candy pieces?
Absolutely. You can leave out the candy and increase the white chocolate chips, or add chopped nuts if desired. The finished bars will be less colorful but still delicious.
Are these the same as traditional cookie bars?
Not exactly. Traditional chocolate chip cookie bars usually have a denser, chewier cookie texture. This recipe includes sour cream and instant pudding mix, giving it a softer, more tender, cake-like consistency.
