Infused Lemon Bars (A Tangy-Sweet Cannabis Classic)

There’s a reason lemon bars never go out of style: that tangy-sweet filling on a buttery shortbread crust is basically sunshine in dessert form. This version swaps part of the butter in the crust for cannabutter, so every square delivers a gentle, even lift along with the citrus. They’re easy to make, easy to dose, and dangerously easy to share — which is exactly why we’ll talk portioning below.

Key takeaways

• Infused lemon bars use cannabutter only in the shortbread crust, which keeps dosing simple and even.
• One 8×8 pan makes 16 bars at roughly 5 mg THC each (using 80 mg total cannabutter) — adjust your cannabutter potency to hit your target.
• Edibles take 30–90 minutes to kick in. Start with one bar (or half), and wait before having more.
• Label and store them sealed in the fridge, well away from kids and pets.

Ingredients

Crust

• 1 cup all-purpose flour
• 1/4 cup granulated sugar
• 1/4 teaspoon salt
• 1/4 cup cannabutter, softened (about 80 mg THC total — see dosing note)
• 1/4 cup regular unsalted butter, softened

Lemon filling

• 3 large eggs
• 1 cup granulated sugar
• 1/2 cup fresh lemon juice (about 3 lemons)
• 1 tablespoon lemon zest
• 1/4 cup all-purpose flour
• Powdered sugar, for dusting

Instructions

1. Preheat the oven to 350°F (175°C). Line an 8×8-inch pan with parchment paper, leaving overhang on two sides for easy lifting.
2. Make the crust: stir together the flour, sugar, and salt. Work in the softened cannabutter and regular butter with a fork (or your fingers) until the mixture looks like damp sand and holds together when pressed.
3. Press the crust evenly into the bottom of the pan. Bake for 18–20 minutes, until the edges are lightly golden.
4. While the crust bakes, whisk the eggs and sugar until smooth, then whisk in the lemon juice, zest, and flour until no lumps remain.
5. Pour the filling over the hot crust and return the pan to the oven. Bake 20–22 minutes, until the filling is set and no longer jiggles in the center.
6. Cool completely at room temperature, then chill for at least 1 hour — the bars slice much cleaner cold.
7. Lift out using the parchment, slice into 16 squares, and dust with powdered sugar just before serving.

Dosing & safety note

Using 1/4 cup of cannabutter containing roughly 80 mg THC total, each of the 16 bars lands around 5 mg THC — a sensible single serving for many adults. Your cannabutter’s actual potency may differ, so do the math for your batch: total mg in the butter ÷ 16 bars. Remember edibles take 30–90 minutes to take effect, so start low and go slow — one bar, then wait. Label the pan clearly, store bars in a sealed container in the fridge away from kids and pets, and keep it legal: only make and enjoy these where cannabis is permitted, and never share infused food without telling people what’s in it. For adults 21+ only. (Bars keep about 5 days refrigerated.)

FAQ

How strong are these infused lemon bars?

With 80 mg THC of cannabutter split across 16 bars, each bar is about 5 mg THC. Use weaker or stronger cannabutter — or cut smaller squares — to adjust the per-serving dose.

Can I put the cannabutter in the lemon filling instead?

Keep it in the crust. The filling is mostly juice, sugar, and egg, so fat doesn’t blend evenly into it — infusing the crust gives a far more consistent dose per bar.

How should I store infused lemon bars?

In a sealed, clearly labeled container in the fridge for up to 5 days. Keep them away from kids and pets, and separate from non-infused desserts.

How long do the effects take to kick in?

Like most edibles, 30–90 minutes, with effects lasting several hours. Eat one bar, wait at least 90 minutes, and only then decide if you want more.
