Coffee Granola Recipe: Crunchy Espresso Clusters

Most coffee-flavored breakfasts taste faintly of coffee at best. This coffee granola recipe uses coffee twice, once as strong brewed espresso in the syrup and once as finely ground coffee tossed with the oats, so every cluster tastes like a good mocha. It bakes in about 40 minutes, keeps for two weeks in a jar, and makes yogurt, milk or even a scoop of ice cream feel like dessert for breakfast.

Below you will find the recipe with US and metric amounts, the tricks for big clusters, an estimate of how much caffeine is in a serving, and variations from decaf to dairy-free.

From Granula to granola: a quick history

Granola started as a health food, and a very hard one. At his sanitarium in Dansville, New York, Dr. James Caleb Jackson developed Granula, made from graham flour and water baked into sheets and crushed. It was so hard it had to be soaked overnight. Sources date it to 1863, and Jackson trademarked the name in the 1870s. When John Harvey Kellogg made a similar cereal at his Michigan sanitarium under the same name, Jackson objected, and Kellogg renamed his version Granola.

The oat, nut and honey granola we know today is a product of the 1960s and 1970s health food movement, when granola became so linked to counterculture that the word turned into slang. Adding coffee is a modern twist, but it fits perfectly: roasted oats and nuts share many of the toasty, caramelized flavors of roasted coffee.

Coffee granola recipe

Makes about 6 cups (roughly 650 g), or 12 servings of 1/2 cup. Prep 10 minutes, bake 35 to 45 minutes.

Ingredients

Steps

1. Heat the oven. Preheat to 300°F (150°C) and line a large rimmed baking sheet with parchment.
2. Mix the dry ingredients. In a large bowl, combine the oats, nuts, seeds, ground coffee, brown sugar, cinnamon and salt.
3. Make the coffee syrup. Whisk the maple syrup, oil, cooled espresso and vanilla until smooth. If using the egg white, whisk it separately until frothy.
4. Combine. Pour the syrup over the dry mix and stir until every oat is glossy. Fold in the egg white last.
5. Press and bake. Spread the granola in an even layer about 1/2 inch (1 cm) thick and press it down firmly with a spatula. Bake for 35 to 45 minutes, rotating the tray halfway, until deep golden and fragrant. For clusters, do not stir; for loose granola, stir every 15 minutes.
6. Cool completely. Leave the tray untouched for at least 45 minutes. The granola crisps as it cools.
7. Break and finish. Break into chunks and stir in the chocolate or cacao nibs once fully cool, so they do not melt.

Storage

Keep the granola in an airtight jar at room temperature for up to 2 weeks, or freeze it for up to 3 months.

How to get big clusters

• Add an egg white. Its proteins set in the oven and glue oats together. Leave it out for a vegan version.
• Press the mixture down before baking, and do not stir during baking.
• Let it cool on the tray. Sugar syrups harden as they cool; moving the granola too early breaks clusters apart.
• Use some liquid sweetener. Maple syrup or honey binds better than sugar alone.

Choosing the coffee

Use a coffee with chocolate and caramel notes; very bright, fruity roasts can taste sour once baked. The espresso in the syrup brings flavor, and the ground coffee adds tiny dark specks and a roasted crunch. Grind the coffee as fine as possible, like espresso or finer, so it does not feel gritty. If you have espresso powder, you can use 2 teaspoons in place of the ground coffee; our guide to espresso powder explains how it differs from instant coffee.

How much caffeine is in coffee granola?

Not much per serving, but not zero. Here is a rough estimate. Roasted Arabica beans typically contain about 1 to 1.5% caffeine by weight, so 5 g of ground coffee holds roughly 50 to 75 mg. A 60 ml double-strength espresso might add another 80 to 130 mg, depending on the beans and dose. That makes roughly 130 to 205 mg for the whole batch, or about 10 to 17 mg per 1/2-cup serving across 12 servings, less than a typical cup of tea. Baking does not meaningfully destroy caffeine.

If you are sensitive to caffeine, pregnant, or making this for children, use decaf coffee for both the espresso and the ground coffee. Caffeine is discouraged for children and teens, according to the American Academy of Pediatrics, as cited by the FDA.

Variations and lighter options

• Mocha granola: add 2 tbsp (12 g) unsweetened cocoa powder to the dry mix.
• Tiramisu-style: serve with mascarpone or thick Greek yogurt and a dusting of cocoa.
• Hazelnut latte: use chopped hazelnuts and add a pinch of nutmeg.
• Lighter: cut the oil to 3 tbsp (45 ml), replace half the maple syrup with unsweetened applesauce and skip the chocolate. Bake a few minutes longer.
• Dairy-free and vegan: the base recipe is dairy-free; skip the egg white and use maple syrup instead of honey.
• Gluten-free: use oats labeled gluten-free.
• Nut-free: replace the nuts with extra seeds.

Ways to serve it

Spoon it over Greek yogurt with berries, pour cold milk over it, scatter it on vanilla ice cream, or pair it with coffee overnight oats for a double-coffee breakfast. It is also an easy gift in a jar; see our coffee gift ideas for more.

Coffee for your granola

Pick a coffee you would happily drink alongside the bowl. Our Italian Roast, intense and smoky with dark chocolate notes, makes a bold granola, while our Mocha flavored coffee, specialty Arabica infused with rich chocolate, leans into the mocha version. For a caffeine-free batch, Decaf Espresso is water-process decaf roasted dark for espresso. Every bag is roasted 1 to 5 days before delivery. Browse our flavored coffees for more ideas.

Coffee granola FAQ

Can I use instant coffee in granola?

Yes. Dissolve 1 to 2 tsp of instant coffee in the warm syrup instead of using brewed espresso, and skip the ground coffee or keep it for texture.

Does coffee granola keep you awake?

A serving of this recipe contains an estimated 10 to 17 mg of caffeine, far less than a cup of coffee. Use decaf if you are sensitive or eating it late.

Why is my granola not crunchy?

It probably needs more baking time or a full cool-down on the tray. Granola stays soft while warm and crisps as it cools.

Can I use used coffee grounds?

It is better to use fresh, finely ground coffee. Spent grounds have given up most of their flavor and can taste bitter and dull.

Is coffee granola healthy?

Like any granola, it is energy-dense because of the oil, sugar and nuts. Enjoy it in moderate portions, and try the lighter version above.
