Gather all your ingredients and tools. Crush the cookies into fine crumbs using a rolling pin or food processor, then set aside.
Whip the cream in a mixing bowl using an electric mixer until soft peaks form, about 3-4 minutes. Set aside.
Prepare the gelatin or jelly cubes according to package instructions, then let them cool until slightly firm but still wobbly.
Begin layering your trifle by spreading a layer of crushed cookies at the bottom of the glass dish, creating a crunchy base.
Spoon a layer of vanilla pudding over the cookies, smoothing it gently with a spatula for an even surface.
Add a layer of chopped fruit, distributing it evenly for bursts of color and fresh flavor.
Spread a layer of whipped cream over the fruit, creating a fluffy, white layer.
Place the cooled gelatin cubes over the whipped cream, pressing them slightly into the layer to help them set.
Repeat the layering process—cookies, pudding, fruit, whipped cream, and jelly—until the dish is full, finishing with a whipped cream layer on top.
Gently spread the remaining whipped cream over the top and refrigerate for at least 2 hours to let flavors meld and layers set.
Just before serving, decorate with gummy worms, spooky sprinkles, and candy eyeballs for a creepy, fun finish.
Serve your colorful Halloween trifle with excitement and enjoy the messy, delightful mix of textures and flavors!
