Espresso Shortbread With Toffee

My apartment smelled like a coffee shop that morning, which was exactly what I'd been going for when I decided to experiment with adding espresso to shortbread dough. I'd been craving something to dunk in my afternoon coffee, something substantial but not too sweet, and these buttery cookies with their golden edges and scattered toffee pieces ended up being the answer.

I brought a batch to my sister's book club last winter, and they disappeared before anyone even opened their wine. One friend kept asking if I'd put coffee grounds in the dough, which made me laugh, but honestly the instant espresso dissolves so completely into the butter that you just get this warm, roasted background note that keeps you coming back.

Ingredients

• Unsalted butter: Room temperature is non negotiable here, cold butter will fight you and give you a dough that feels like it's resisting existence
• Powdered sugar: Creates a more tender crumb than granulated sugar would, plus it dissolves beautifully into the butter without any graininess
• Instant espresso powder: Not instant coffee crystals, but the fine powder meant for baking, it disperses evenly and won't leave gritty spots in your dough
• Pure vanilla extract: Don't skip this, it bridges the gap between the coffee notes and butter in a way that feels complete
• All purpose flour: Spoon and level it instead of scooping directly, too much flour will make these dry instead of meltingly tender
• Salt: Just enough to wake up all the flavors without making these taste savory
• Toffee bits: I like the store bought ones but homemade toffee chopped into irregular pieces adds these wonderful pockets of buttery crunch

Instructions

Get everything ready:

Preheat your oven to 350°F and line two baking sheets with parchment paper, having everything measured and waiting will make this process feel calm instead of rushed

Cream the butter and sugar:

Beat them together until the mixture looks pale and fluffy, about 2 to 3 minutes, this step creates air pockets that make the cookies tender

Add the flavor:

Mix in the espresso powder and vanilla extract until everything is fully incorporated and the dough looks uniformly speckled

Bring it together:

Gradually add the flour and salt, mixing just until the dough forms, over mixing here will make your cookies tough instead of tender

Fold in the toffee:

Use a spatula to fold in the toffee bits by hand, making sure they're evenly distributed throughout the dough

Shape the cookies:

Scoop tablespoon sized balls onto the baking sheets, leaving about 2 inches between each, then flatten slightly with your hand or a glass bottom

Bake until golden:

Bake for 16 to 18 minutes until the edges are just turning golden, they'll still look slightly soft in the center but that's exactly right

Cool completely:

Let them rest on the baking sheet for 5 minutes to set, then transfer to a wire rack to cool completely before storing

Save

My mom started calling them her coffee break cookies and now requests a batch whenever she has friends over for morning tea. There's something about the combination of buttery shortbread and that hint of espresso that feels like a small luxury in the middle of an ordinary day.

Making Them Your Own

I've swapped half the toffee bits for chopped dark chocolate when I wanted something closer to a mocha cookie, and the result was this rich, slightly bittersweet version that my chocolate loving friends couldn't stop eating. The key is keeping the mix ins to about 3/4 cup total so the dough still holds together properly.

Storage Tips

These actually get better after a day or two, as the flavors meld together and the texture becomes even more tender. I store them in a tin rather than plastic, something about the metal container keeps them from getting soft or stale too quickly.

Serving Suggestions

Serve these with afternoon coffee or tea, but they're also unexpected alongside vanilla ice cream for a simple dessert. Try crumbling them over Greek yogurt for breakfast.

• A sprinkle of flaky sea salt on top before baking creates this sweet salty thing that's addictive
• If your espresso powder has clumps, grind it in a mortar and pestle or give it a quick whirl in a spice grinder
• For gift giving, stack them in a clear bag with a handwritten note about the coffee inside

Save

Whatever you do, don't judge the dough before it's baked. The raw mixture seems plain and unremarkable, but something magical happens in the oven that transforms it into something people will ask you to make again and again.

Common Questions

→ Can I use regular coffee instead of espresso powder?

Instant espresso powder is recommended because it dissolves completely and provides concentrated coffee flavor without adding extra liquid. Regular instant coffee can be used, but the flavor will be milder. If using brewed coffee, you'd need to reduce other liquids, which would affect the dough consistency.

→ What type of toffee bits work best?

Store-bought toffee bits like Heath or Skor are convenient and work beautifully. For a homemade touch, you can crush up store-bought toffee bars or make your own. Just ensure the pieces are small enough to distribute evenly—roughly pea-sized pieces are ideal.

→ Why did my dough seem too dry or crumbly?

Shortbread dough should be crumbly before coming together. If it's not forming a cohesive dough, the butter may have been too cold. Let it soften slightly or pulse the mixture in a food processor. Avoid adding liquid—instead, continue mixing until the flour hydrates and the dough forms.

→ Can I freeze the dough or baked cookies?

Absolutely. Scoop the dough into balls, freeze on a baking sheet, then transfer to a freezer bag for up to 3 months. Bake straight from frozen, adding 1–2 minutes to the baking time. Baked cookies also freeze well for up to 3 months when stored in an airtight container with parchment between layers.

→ What's the best way to achieve evenly sized cookies?

Use a cookie scoop or tablespoon measure to ensure consistent portions. This helps all cookies bake at the same rate. If you don't have a scoop, roll the dough into balls and weigh them—about 20 grams each is ideal for uniform baking.

→ Can I make these dairy-free?

While traditional shortbread relies heavily on butter for its signature texture, you can experiment with high-quality vegan butter sticks. Avoid tub margarine as it contains too much water. The texture may differ slightly, but the espresso and toffee flavors will still shine through.
