Key Ingredients for Copycat Costco Heavenly Hunks

See recipe card below for full list of measurements, ingredients, and instructions.

Brown Rice Syrup

The secret to that signature chewy pull and clean slice. Its thick, sticky consistency binds the oats without making the bites gritty or overly sweet. Look for brown rice syrup in the baking or natural foods aisle. If you substitute honey or maple syrup, the texture will be softer and less chewy, so pack the mixture extra firmly and chill longer. A 50-50 mix of maple syrup and light corn syrup is a decent stand-in for texture.

Oats

Oats build the body and classic nubby texture. Use a mix of old-fashioned rolled oats for chew and quick oats for cohesion. If you only have rolled oats, pulse a portion in a food processor 3 to 4 times to mimic quick oats. Use certified gluten-free oats if needed to keep the recipe gluten free.

Oat Flour

A little oat flour fills the gaps between the larger oat flakes and helps everything hold together cleanly. You can buy it or make your own by blending oats to a fine flour. Almond flour works in a pinch but will create a slightly softer, richer bite.

Mini Dark Chocolate Chips

Mini chips distribute evenly so you get chocolate in every bite without crumbling the bars. Choose dairy-free chips to keep the recipe vegan. Regular chips or chopped chocolate work, but let the mixture cool a minute before adding so they do not melt.

Coconut Oil and Shredded Coconut

Coconut oil firms the bites as they chill, giving that clean edge when you cut. Use refined coconut oil if you prefer less coconut flavor. Unsweetened fine shredded coconut adds richness and a delicate chew. If you are coconut-averse, replace the shredded coconut with the same amount of quick oats, and use a neutral oil like avocado oil, understanding the texture will be a touch less lush.

Copycat Costco Heavenly Hunks cooking process

Instructions for Copycat Costco Heavenly Hunks

See recipe card below for full list of measurements, ingredients, and instructions.

Line and Prep the Pan

Line an 8-inch square pan with parchment, leaving overhang on two sides for easy lifting. Lightly mist the parchment with oil to prevent sticking. Set aside and clear a little counter space for pressing.

Warm the Binder

In a small saucepan over low heat, combine brown rice syrup, coconut sugar, coconut oil, and cashew butter. Stir until smooth and just loosened, 1 to 2 minutes. Remove from heat, then stir in vanilla and sea salt. You want it warm and fluid, not hot.

Mix the Dry Ingredients

In a large bowl, stir together rolled oats, quick oats, oat flour, and shredded coconut. Break up any clumps so the flour distributes evenly.

Combine and Fold in Chocolate

Pour the warm syrup mixture over the oat mixture. Use a sturdy spatula to fold until every bit is evenly moistened and there are no dry pockets. Let the mixture sit 1 to 2 minutes to cool slightly, then fold in mini chocolate chips so they stay intact.

Pack and Compress

Transfer the mixture to the prepared pan. Spread into an even layer, then lay a second sheet of parchment on top and press very firmly with your hands or the bottom of a measuring cup. Compressing well is key for clean cuts and a cohesive chew.

Chill and Slice

Chill until set, 30 to 45 minutes. Lift out using the parchment overhang and place on a cutting board. Use a sharp knife to cut 4 by 4 for 16 hunks, or smaller 5 by 5 for bite-size pieces. For the neatest squares, wipe the knife between cuts.

Recipe Variations

Nut-Free and School Safe

Skip the cashew butter and use sunflower seed butter. Choose allergy-friendly chocolate chips. The texture stays chewy and the flavor is slightly toasty.

Chocolate Peanut Butter Twist

Swap in peanut butter for cashew butter and add 1 tablespoon cocoa powder to the dry mix. Fold in a sprinkle of roasted peanut pieces for crunch.

Protein Boost

Stir 1 to 2 scoops of vanilla plant protein powder into the dry mix, then add 1 to 2 tablespoons extra brown rice syrup or a splash of dairy-free milk to keep the mixture cohesive.

Baked and Firmer

Prefer a sturdier bar for travel? Press into a parchment-lined pan and bake at 325 F for 8 to 10 minutes until edges look set. Cool completely before slicing.

Serving Suggestions

Serve these hunks with fresh berries and Greek yogurt for a quick snack plate, or pair with coffee for an afternoon pick-me-up. Sprinkle with flaky sea salt after slicing, or drizzle with melted dark chocolate for a dessert-worthy finish.

Storage and Reheating

Store hunks in an airtight container at room temperature for up to 3 days if your kitchen is cool, or refrigerate up to 1 week for best texture. For longer storage, freeze in a zip-top bag with parchment between layers for up to 3 months. No reheating needed. Thaw frozen pieces at room temperature for 10 to 15 minutes or enjoy slightly chilled.

Frequently Asked Questions About Copycat Costco Heavenly Hunks (FAQ)

Q: Can I make these gluten free and vegan like the original?

A: Yes. Use certified gluten-free oats and dairy-free mini chocolate chips. The rest of the ingredients are naturally vegan.

Q: What can I use instead of brown rice syrup?

A: For similar chew, use a 50-50 mix of maple syrup and light corn syrup. Honey or pure maple works too, but the bites will be softer and may need extra pressing and a longer chill.

Q: Why are my hunks crumbly when I cut them?

A: Usually they were not packed firmly enough or the mixture was too dry. Press harder, chill at least 45 minutes, and if needed mix in 1 to 2 tablespoons additional brown rice syrup, then re-press.

Q: Can I leave out the shredded coconut?

A: Yes. Replace it with the same amount of quick oats or 1 to 2 tablespoons less if your mix seems dry. The flavor will be less rich but still delicious.
