Infused Carrot Cake — The Spice Cake, Counted by the Slice

Carrot cake is a spice cake first and a vegetable cake second, and that is exactly why it carries a dose so well. Cinnamon, ginger, nutmeg, and clove are loud, warm, and forgiving — they wrap around any herbal note and make it taste like intention instead of accident. The trick in this post is the opposite of the frosting posts: the cake itself carries the count, the cream cheese frosting stays completely clean, and the slice is the dosing instrument. Twelve even slices, one number, no guessing at the table.

🔥 Decarboxylation: Wake the Flower Up First

Raw flower will not do the job — the THC is still wearing its acid jacket as THCA, and heat is what takes it off. So before anything gets infused, the flower gets activated:

Decarb: 3.5g flower, broken up by hand (never ground to dust), spread on a parchment-lined sheet pan, covered tightly with foil, baked at 240°F for 40 minutes. Cool completely before opening the foil — the good stuff is in the trapped vapor, and you want it in the jar, not in the kitchen air.
Why 240°F for 40 minutes: This is the house standard — hot enough to convert THCA to THC reliably, gentle enough to keep the terpene character from boiling off. The cake will bake at 350°F, but the dose is already activated before it ever meets the batter, and the crumb protects it from the worst of the oven heat.

🧈 The Infusion: Classic Cannabutter

The workhorse infusion, made once and kept for the whole week of baking:

Method: Melt 1 cup (2 sticks) unsalted butter with the decarbed flower in a small saucepan or double boiler, hold at 160–180°F for 2 hours, stirring occasionally. Strain through cheesecloth, squeeze gently, and jar.
Base: Unsalted butter. Temp: 160–180°F. Time: 2 hours. Yield: About 1 cup (16 tablespoons).
Dosing math: 3.5g at 20% THC = 3500mg × 0.20 = 700mg THCA × 0.877 = ~614mg THC × 0.75 efficiency ≈ ~460mg THC per cup of butter → ~29mg per tablespoon, ~10mg per teaspoon.
Storage: Fridge 4 weeks, freezer 6 months. Label it clearly: strain, date, mg per teaspoon. Keep it far away from the undosed butter — same foil wrapper, very different job.

🥕 The Recipe: Infused Carrot Cake, 12 Slices

The batter carries the count — the frosting stays clean, and the slice does the math:

The butter blend (the dosing decision):

Never bake with 100% dosed butter unless you have done the math and like the number. This cake uses ¼ cup dosed butter + ¼ cup plain butter (plus ¼ cup neutral oil for moisture). A quarter cup of dosed butter is about 115mg THC for the whole cake — divided by 12 slices, that is a sane number, and a mistake in one direction only ever halves the dose, never doubles it.

Ingredients:

2 cups flour, 2 teaspoons baking soda, 2 teaspoons cinnamon, 1 teaspoon ginger, ½ teaspoon nutmeg, ¼ teaspoon cloves, 1 teaspoon salt
¼ cup dosed butter, melted and cooled + ¼ cup plain butter, melted and cooled + ¼ cup neutral oil
1½ cups sugar, 4 eggs, 2 teaspoons vanilla
3 cups grated carrots, 1 cup crushed pineapple, drained, ¾ cup chopped walnuts (optional)
Clean cream cheese frosting: 8 oz cream cheese + ½ cup plain butter + 3 cups powdered sugar + 1 teaspoon vanilla, beaten smooth

Method:

Heat the oven to 350°F. Grease and line two 8-inch round pans. Whisk the dry ingredients together — the spice blend is the camouflage, so measure it honestly.
Blend the fats first. Whisk the dosed butter, plain butter, and oil together before anything else goes in, so the dose is evenly distributed through the fat. Sugar added to uneven butter locks the unevenness in.
Build the batter. Beat in the sugar, eggs, and vanilla, fold in the carrots, pineapple, and walnuts, and divide evenly between the pans — weigh the pans if you want identical layers.
Bake 30–35 minutes, until a toothpick comes out clean. Cool completely before frosting — warm cake melts frosting and smears the clean/dosed line.
Frost clean, slice counted. Frost with the plain cream cheese frosting, then cut 12 even slices: halve, quarter, then thirds. Write the number on the cake box before it goes in the fridge.

📐 Dosing Math

Whole cake: ¼ cup dosed butter ≈ 115mg THC total
Per slice: 115mg ÷ 12 slices ≈ ~10mg THC per slice
Half a slice → ~5mg — where most guests should start
The frosting, the plates, the serving knife: all clean. Only the crumb carries the count, and the slice count is written on the box.

🧬 Terpene Pairing

Primary terpenes: Caryophyllene (the warm black-pepper spice that mirrors cinnamon and clove) + humulene (the woody, hoppy depth under ginger) + limonene (the bright lift that keeps a spice cake from tasting heavy)
How to use it: Match the strain to the spice rack, not the carrot. Warm, peppery strains disappear into cinnamon and nutmeg; bright citrus strains lift the pineapple. The carrots are just the vehicle — the spices do the pairing work.
What to avoid: Heavy diesel or skunk strains in a spice cake — the spices will fight them instead of hiding them, and the cake will taste confused. Keep it warm and peppery, never louder than the cinnamon.

🌱 Strain Suggestions

Wedding Cake (Hybrid, ~22% THC) — Caryophyllene, limonene. Sweet spice and vanilla warmth — the spice cake's mirror.
Granddaddy Purple (Indica, ~20% THC) — Myrcene, caryophyllene. Deep berry warmth — the evening-slice companion.
Blue Dream (Hybrid, ~19% THC) — Myrcene, pinene. Gentle herbal warmth — the all-purpose baking companion.

📏 Dosage

Per slice: ~10mg THC — a full, real serving; respect it
Half slice: ~5mg — the sane starting point
Onset: 60–90 minutes — the butter and oil absorb steadily, and the spice cake carries it long
The gentle rule: Anyone who wants an undosed slice gets a plain slice cut first, before the dosed cake comes out — or better, bake a second clean cake. The box gets labeled before it goes in the fridge, every time.

Start with one serving. Wait 90 minutes before even thinking about a second. For adults 21+ only. Consume responsibly and in accordance with local laws.

🥕 Chef Smoke's Carrot Cake Rule: "The spices are the camouflage and the slice is the scale. Blend the fat first, cut twelve even slices, frost it clean, and let the cake do the only job that matters: carry the count where everyone can see it, one slice at a time."
