Chocolate sheet cake
A thin sheet cake cut into a grid, which makes it the easiest cake to dose accurately. The frosting carries the infusion so none of it goes through the oven.

½ cup infused butter
Set your infusion strength above and this splits into infused and plain butter to hit whatever dose you want.
- 3 cupspowdered sugar
- ⅓ cupunsweetened cocoa powder
- 4 tbspwhole milk
- 2 cupsall-purpose flour
- 2 cupsgranulated sugar
- ¾ cupunsweetened cocoa powder
- 2large eggs
- 1 cupbuttermilk

- 1 cuphot coffee
- 2 tspbaking soda
- 1 tspfine salt
Method
- 01
Heat the oven to 350 °F and grease a 9x13 pan.
350 °F
- 02
Whisk all the cake dry ingredients together, then beat in the eggs, buttermilk and plain oil until smooth.
- 03
Stir in the hot coffee last. The batter will look alarmingly thin — that is correct and it is what makes the crumb tender.
- 04
Bake until the center springs back.

- 05
Cool completely. The frosting carries the dose and it must not go onto a warm cake — melting it would run the infusion to the edges.
- 06
Beat the infused butter with the powdered sugar, cocoa and milk until smooth and spreadable. Add milk a teaspoon at a time if it is stiff.
- 07
Spread evenly right to the corners. Even frosting is the whole dosing story here, since the cake underneath carries nothing.
- 08
Mark a 4x5 grid before you cut, then cut 20 even squares.
Built on
Standard oil-based chocolate cake: 2 cups flour, 2 cups sugar, ¾ cup cocoa, 2 eggs, 1 cup buttermilk, 1 cup hot coffee, baked thin.
Every recipe here names the conventional ratio underneath it. The cannabis part is a fat substitution, not new chemistry — so if the base is sound and the substitution is sound, the recipe is sound.

Before you eat it
- These are estimates, not lab results. Treat the low end as the honest number and the high end as the thing to plan around.
- Start with one serving and wait two hours. Edibles take 30 to 120 minutes to come on, and the most common mistake is redosing before the first one lands.
- Test a small piece first. Potency is rarely even across a batch, especially if the infusion was not mixed thoroughly.
- Label anything you store with the date and the estimated dose, and keep it away from children, pets and anyone who did not ask for it.
- If you overdo it: you are not in danger, but it will be unpleasant. Find somewhere quiet, drink water, and wait it out. Do not drive.

Brown butter chocolate chip cookies
The standard creamed-butter drop cookie, with the butter browned first. Browning drives off water and deepens the flavor enough to cover any grassiness in the infusion.
24 cookies
Fudgy one-bowl brownies
A high-fat, low-flour brownie that bakes dense rather than cakey. The cocoa does most of the work of hiding the infusion.

No-bake peanut butter cups
Two layers, a muffin pan and a freezer. No oven, no smell, and the dose lives in the filling where you can measure it exactly.
