Sabrina’s Fruit and Nut Granola Clusters Recipe
So many of us are fans of Costco products, especially the Kirkland Signature items, that you can only get at their store. However, you may not always be up to a Costco trip. This copycat version is an amazing way to get your favorite Costco snack without having to go through all the trouble of searching the aisles or trying to find parking on weekends. You can even store it in bulk, no membership card required!
Chef’s Note: Why make this at home?
One of the great things about making copycat versions of your favorite food is that you know exactly what goes into the recipe. So, you can always adjust the recipe as you see fit. If you have health goals you’re trying to meet, you can decrease the amount of sugar from the store-bought granola. You can also leave out ingredients you don’t like, or that you’re allergic to. Making your own Copycat Costco Granola means you’re in control of all the ingredients and nutrition.

Ingredients
- Syrup: To make the syrup you need 1 cup butter, ½ cup maple syrup, ½ cup maple syrup, 1 cup brown sugar, and ⅓ cup water. The combination of different kinds of sweeteners gives the recipe a more complex and rich, sweet flavor than just one would. Then add a hint of cinnamon and vanilla to finish it off.
- Fruit & Nuts: This granola is so filling, due in part to the protein-packed nuts in the mix. You’ll use 1 cup each of cashews, almonds, and walnuts for variation of flavor and crunch. For the fruit in the granola clusters, you only need 1 cup each of dried cranberries and raisins to add some chewiness to the crunch.
- Granola: Use 5 cups quick oats for the granola mixture. You’ll grind down some of the oats to mix with whole oats for variations in texture, and the ground oats will also help blend all the ingredients together.
Kitchen Tools & Equipment
- Cookie Sheet and Parchment Paper: A cookie sheet will allow the granola to spread nice and thin, in order to toast up well. In the end you’ll be so glad you used parchment paper as it will prevent the sweet mixture from sticking to the pan.
- Food Processor: Grab your trusty food processor to process the oats into flour. This step is really important for the texture of the finished granola.
- Large Pot and Spatula: Use a pot large enough to handle the 13 cups of ingredients you have, with room to stir.
How to Make
Time needed: 1 hour and 15 minutes.
- Prep Time
Start by preheating the oven to 350 degrees. Line a cookie sheet with parchment paper and set it to the side while you prep the ingredients.
- Oat Flour
Add half of the quick oats to your food processor, and pulse until they’re ground into a flour.
- Oat, Nut, Fruit Mixture
Then add the oat flour to a mixing bowl along with the rest of the oats. Stir the almonds, cashews, walnut halves, dried cranberries, and raisins into the oat mixture.
- Sugar Mixture
Add the butter, brown sugar, maple syrup, honey, and water to a large pot. Then set the stovetop to medium high heat. Stir as the butter melts, and bring the mixture to a boil.
- Finish Syrup
Once it’s boiling, turn the heat off and stir in the vanilla, cinnamon, and salt.
- Combine
Then add the granola, nut & fruit mixture to the pot. Stir until the granola is all coated in the homemade syrup.
- First Bake
Pour the sweetened fruit and nut mixture over the prepared baking sheet. Then use your hands to press it into an even layer. There will still be some gaps throughout. Put the dish in the oven for 25-30 minutes until it’s golden brown.
- Second Bake
Then let it all cool, and break it into Fruit and Nut Granola Clusters. Bake for an additional 15 minutes.
- Serve or Store
Let the Copycat Costco Granola cool completely before eating or storing in an airtight container.

Recipe Tips & Tricks
- Don’t Skip the Second Bake
- That will really add the extra crunch to your granola, especially once you break it up and create more surface area to toast in the oven.
- Adjust for Substitutions
- If you make substitutions, be sure to adjust the other ingredients so you still have the same measurements. If you simply omit one of the nuts in the recipe, you’ll have too much syrup and the mixture will be too wet. Add more of the other nuts to create balance in the recipe.
How to Store
- Serve: After you cool and break the granola into pieces, you can keep the recipe at room temperature for up to 3 months. Just make sure to seal the Fruit and Nut Granola Clusters in an airtight container.
- Store: If you keep your house warm and are worried about the sugars in the recipe becoming sticky, you can also keep the mixture in the fridge. Package the copycat recipe in a ziplock bag and keep it in the fridge for 3-4 months.
- Freeze: Because all the fruits in the mix are dry, you can also freeze this recipe. Just seal it in a freezer-safe, airtight container. Then it can stay good for up to 6 months.

Frequent Questions
Yes, you can add sunflower seeds, hemp seeds, pumpkin seeds, or flax seeds to replace some of the nuts in this recipe. Just be sure you replace the same volume of nuts that you reduce in the recipe.
When you’re cooking the syrup on the stovetop, you’re doing that so you can melt all the ingredients together, including the sugar granules. Adding the chunky granola ingredients is simply so you can toss everything in that syrup. The oven bake is what makes your granola crispy.
It is the syrup that works as the sticky, sweet, delicious glue for your granola. That’s why it is important to cook everything together and toss the ingredients together very well, coating everything in the syrup.
Yes, oats are naturally gluten-free and I did not use any gluten-containing ingredients in my recipe so these granola clusters are gluten free. However, keep in mind some processing plants also process flour so if you are highly sensitive, check the label on your quick oats for a gluten-free guarantee.
Variations
- Granola Bars: Instead of making this recipe into Fruit and Nut Clusters, you can bake it into protein bars. Simply add the ingredients to your pan in a more tight formation. Then when it’s done baking and has cooled, you can use a knife to cut the nut and fruit mix into evenly sized bars. They make an ideal snack to take with you on a hike or for an on-the-go breakfast. You can also keep frozen fruit bars in your freezer, and bring them out any time you need easy snacks for a road trip or camping trip.
- Chocolate Chips: If you want a chocolate mix-in, just add a cup of chocolate chips into the mix. You can use semisweet chocolate, dark chocolate, milk chocolate, or white chocolate chips. You can also add in some salty peanut butter flavor with peanut butter chips.
- Extra Mix-Ins: The great thing about a snack mix like this is that you can add any of your favorite kinds of sweet and salty mix-ins to the recipe. Yogurt covered raisins, golden raisins, m&ms, or chocolate chunks.
