This cannabis dump cake is an easy edible dessert with three layers and no mixing bowl. Pie filling goes on the bottom, dry cake mix in the middle and thin slices of butter on top. The one change that matters is the butter: a dump cake uses a lot of it, so you blend cannabutter with plain butter for a sensible dose per square.
Why the butter gets blended
This recipe takes 3/4 cup (12 tablespoons) of butter. Made with all cannabutter, each square could carry far more THC than most people want from dessert. So use just enough cannabutter for your target and make up the rest with plain butter. With an example cannabutter of about 15 mg THC per tablespoon, the blend works out like this:
| Cannabutter | Plain butter | Estimated THC per square (12 squares) |
|---|---|---|
| 2 tablespoons | 10 tablespoons | About 2.5 mg |
| 4 tablespoons | 8 tablespoons | About 5 mg |
| 8 tablespoons | 4 tablespoons | About 10 mg |
Your cannabutter will differ, so run the math with your own estimate. For scale, Michigan caps a store-bought adult-use edible at 10 mg THC per dose, as of October 2026. Our THC dosage guide covers choosing a starting amount.
What goes in a cannabis dump cake

Layer it evenly
Even layers mean even doses. Spread the filling into the corners, dot the cheesecake filling across it and sprinkle the cake mix in a level layer without stirring. Mash the cannabutter and plain butter together, chill the blend until firm, then slice it thin and tile it over the top until almost no dry mix shows. The melting butter is what turns the mix into cake.
Variations
- Apple filling with cinnamon, or peach with nutmeg.
- Blueberry with lemon zest, or cherry over chocolate cake mix.
- Vegan: a dairy-free cake mix, with coconut cream and measured canna-oil in place of the butter.

Cut, store and label
Let the cake cool for at least 30 minutes, then score 12 equal squares with a ruler or bench scraper. Cover the pan, label it 'contains THC' with the dose per square and the date, and refrigerate within two hours. Leftovers keep 3 to 4 days, and every container that leaves the pan gets its own label. Keep it away from children and pets, and if someone eats a square by accident, call Poison Control at 1-800-222-1222.
