Fudgy Weed Brownies — Simple, Dense Chocolate Brownies

Molten, dark, and impossibly fudgy — these Fudgy Weed Brownies melt on the tongue and hold a glossy, crackly top. I developed this version after testing it 12 times to balance texture, chocolate intensity, and consistent dosing. The recipe uses a short, high-fat batter for a dense crumb and a single-pan method that fits most home ovens. I tested variations with different chocolates and butter types to settle on the most forgiving formula. Read on for step-by-step technique, dosing guidance, and pro tips to avoid common failures and get reliable results every bake.

Why This Recipe Works

High chocolate-to-flour ratio yields a dense, fudgy crumb rather than cake-like rise.
Melted chocolate and whole butter give a glossy top and tight internal structure.
Brief whisking after adding eggs traps a little air for lift without drying the crumb.
Decarboxylation of cannabis ahead of time ensures reliable psychoactive activation.
A short bake at moderately high heat sets edges while keeping the center molten.

Ingredients Breakdown

170 g (6 oz) unsalted butter — provides richness and carries cannabinoids; do not substitute with margarine.
170 g (6 oz) dark chocolate (60–70% cocoa) — melting chocolate gives flavor and sheen; lower cocoa will make sweeter, lighter brownies.
250 g (1 1/4 cups) granulated sugar — balances bitterness; you can use 200 g (1 cup) granulated + 50 g (1/4 cup) light brown sugar for a chewier crumb.
3 large eggs, room temperature — structure and shine; you can substitute 3/4 cup (180 g) silken tofu pureed + 1 tsp baking powder for an egg-free option (texture will be slightly different).
75 g (2/3 cup) all-purpose flour — minimal flour keeps the center fudgy.
35 g (1/3 cup) Dutch-process cocoa powder — adds chocolate depth; natural cocoa will work but adjust baking soda vs. powder in recipes that use leaveners.
1/4 tsp fine salt — balances sweetness. Use Diamond Crystal kosher salt if you prefer; if using Morton, halve the quantity.
1 tsp vanilla extract — flavor enhancer.
Cannabis-infused butter or oil, measured for dosing — see dosing notes below. Substitute carefully: swapping infused fat for regular fat changes texture and potency.

Dosing note: Use a tested concentrate to make infused butter. If using a supermarket cannabis butter, confirm potency on the label. I recommend calculating total mg THC per batch before portioning.

Essential Equipment

20 x 20 cm (8 x 8 inch) square baking pan — a smaller pan concentrates batter for a dense center; do not use a 9 x 13 inch or the batter will be thin.
Parchment paper that covers the pan edges — makes removal clean and prevents over-browning on the sides.
Heatproof bowl and saucepan for a double boiler — or a microwave-safe bowl for careful melting.
Digital scale — precise weights matter; cups vary.
Instant-read thermometer — helpful for measuring chocolate temperature while melting.
Offset spatula or rubber spatula — for spreading batter evenly.
If you don’t have a square pan, use a 23 x 23 cm (9 x 9 inch) pan but expect a slightly thinner bake and reduce oven time by 2–4 minutes.

Prep Time: 20 minutes | Cook Time: 22–26 minutes | Inactive Time: 60 minutes (decarboxylation) | Total Time: about 1 hour 50 minutes | Servings: 12 brownies (1 brownie = 1 serving)

Step 1: Decarboxylate the cannabis (inactive, precise)

Preheat the oven to 110°C (230°F). Coarsely break 7–10 g cannabis flower and spread in a single layer on a baking sheet lined with parchment; bake for 40–60 minutes, stirring every 15 minutes, until lightly toasted and dry to the touch. Cool fully; this converts THCA to THC for predictable potency. Timing note: 40–60 minutes is typical; heavier buds may need the full time.

Step 2: Make infused butter (active 10–15 minutes, plus straining)

Combine 170 g (6 oz) unsalted butter and your decarboxylated cannabis (amount based on desired potency) in a small saucepan with 120 ml (1/2 cup) water and simmer on low for 60–90 minutes, keeping the mixture just below a simmer and stirring occasionally. Strain through cheesecloth into a container and chill until the butter solidifies and separates from water. Do not overheat — keep under 95°C (203°F) to protect cannabinoids and volatile flavor. If using a lab-tested concentrated oil, skip this step and substitute some of the recipe’s butter with the-infused fat per your potency calculation.

Step 3: Melt chocolate and butter (active 5–7 minutes)

Preheat the oven to 180°C (350°F). In a heatproof bowl set over barely simmering water, melt 170 g (6 oz) dark chocolate and 170 g (6 oz) butter together until smooth, stirring every 20–30 seconds; remove from heat and cool 3 minutes. Alternatively, microwave in 20-second bursts, stirring between bursts. The mixture should be glossy and pourable. Temperature cue: chocolate should be around 40–45°C (104–113°F) when you add it to eggs.

Step 4: Whisk eggs and sugar (active 1–2 minutes)

In a separate bowl, whisk 3 large eggs and 250 g (1 1/4 cups) sugar vigorously until slightly pale and glossy, 60–90 seconds. Add 1 tsp vanilla extract. Do not under-whisk — a short whisk creates a light suspension that helps the brownies rise just enough without drying.

Step 5: Combine and fold (active 1–2 minutes)

Pour the slightly cooled chocolate-butter mixture into the eggs while whisking constantly to temper and prevent scrambling, then fold in 75 g (2/3 cup) all-purpose flour, 35 g (1/3 cup) Dutch-process cocoa, and 1/4 tsp salt with a rubber spatula until no dry streaks remain — stop immediately. Do not overmix — stop as soon as the batter looks uniform.

Step 6: Bake (active 22–26 minutes)

Scrape batter into a parchment-lined 20 x 20 cm (8 x 8 inch) pan and smooth the top. Bake at 180°C (350°F) for 22–26 minutes, rotating halfway. Bake until the edges are set and a toothpick inserted in the center comes out with a few moist crumbs — the center should look slightly underbaked. Remove and cool in the pan for at least 30 minutes to finish setting. Cooling time is essential for clean cuts.

Step 7: Portion and label (inactive 10 minutes)

Lift brownies from the pan using the parchment overhang and chill for 1 hour if you prefer clean slices. Score into 12 squares. Clearly label and store with dosing information per piece. If you used infused butter, calculate mg THC per brownie: total mg THC in butter ÷ number of servings. Example: 1000 mg total ÷ 12 = ~83 mg per brownie — potent, so adjust serving size accordingly.

Expert Tips & Pro Techniques

Measure by weight. Weighing chocolate and flour prevents dry or gummy results.
Common mistake: overbaking. Fix by taking brownies out when the center still has moist crumbs; they continue to set while cooling.
Make-ahead: Bake and cool fully, then wrap airtight and refrigerate up to 4 days or freeze individual squares for up to 3 months.
Professional trick: tempering the egg mixture with warm chocolate prevents scrambled eggs and gives a glossy top.
If you want a fudgier center, reduce flour by 10 g (about 1–2 tbsp). If you want more cake-like brownies, add one extra egg.
Use an instant-read thermometer: center temperature around 90–95°C (194–203°F) indicates set edges with fudgy middle.

Storage & Reheating

Refrigerator: Store in an airtight container for up to 4 days. Keep brownies labeled with dosing info and never mix with non-infused baked goods. For the best texture, press a layer of parchment between stacked brownies.
Freezer: Freeze individually wrapped brownies in an airtight container for up to 3 months. Thaw overnight in the fridge or at room temperature for 1–2 hours before serving.
Reheating: For a just-baked feel, warm a single brownie in a 175°C (350°F) oven for 6–8 minutes. Avoid microwaving — it can make the crumb gummy and may unevenly heat cannabinoids.

Variations & Substitutions

Gluten-Free Version: Replace 75 g (2/3 cup) all-purpose flour with a 1:1 gluten-free blend (e.g., Bob’s Red Mill). Add 1/4 tsp xanthan gum if the blend lacks binding agents. Baking time may increase by 2–4 minutes.
Vegan / Egg-Free: Use 180 g (3/4 cup) silken tofu blended until smooth and 1 tsp baking powder. Expect a denser, slightly less shiny top and a softer crumb.
Salted Caramel Swirl: Warm 100 g (1/2 cup) salted caramel and swirl 60 g (1/4 cup) into the batter before baking. Try our caramel swirl method for swirl technique.
Higher Cocoa Intensity: Swap half the cocoa powder for melted 70–80% chocolate (reduce added chocolate by 30 g / 1 oz). Keep the rest of the formula identical.
Nutty Crunch: Fold in 80 g (3/4 cup) toasted walnuts or pecans at the end. Toast for 6–8 minutes at 175°C (350°F) until fragrant.

Serving Suggestions & Pairings

Dust with a light sprinkle of powdered sugar and serve with a small scoop of vanilla ice cream for contrast.
For a bright counterpoint, top with fresh raspberries and a drizzle of dark chocolate sauce. See a chocolate-covered strawberry pairing idea at our strawberry brownie pairing.
Pair with strong coffee or a short espresso; the bitterness cuts the richness.
Holiday twist: add green and red sprinkles or small festive toppers, inspired by this festive brownie idea.

Frequently Asked Questions

Q: Why did my brownies turn out dry and cakey?
A: You likely overbaked them or used too much flour. Check with a toothpick early; take them out when the center has moist crumbs. Reduce bake time by 2–4 minutes next time.

Q: Can I make these without eggs?
A: Yes. Use 180 g (3/4 cup) blended silken tofu or a commercial egg replacer. Texture shifts to slightly denser and less glossy but still fudgy.

Q: Can I double this recipe?
A: Yes, double all ingredients and bake in a 23 x 33 cm (9 x 13 inch) pan. Bake time may decrease by 2–6 minutes due to the larger surface area — start checking early. For larger scale bakes, divide batter between two pans for more consistent results.

Q: Can I prepare these the night before?
A: Absolutely. Bake, cool, and refrigerate in an airtight container. Bring to room temperature before serving or warm briefly in the oven.

Q: How long does this keep in the fridge?
A: Stored airtight, brownies keep up to 4 days in the refrigerator. Freeze for longer storage up to 3 months.

Q: How do I calculate THC per brownie?
A: Add up the total mg THC in the infused butter or oil you used, then divide by the number of servings. Example: 1,000 mg THC total ÷ 12 brownies ≈ 83 mg THC per brownie. Start with a small portion and wait at least 90 minutes to assess effects.

Q: Are there safer ways to dose for beginners?
A: Yes. Make smaller servings or halve the infused fat potency by mixing infused butter with equal parts plain butter. Label servings clearly and keep away from children.
