What can I bake without butter or oil?

Help. I've got an afternoon tea to go to this afternoon and I've realised I forgot to get butter and rice bran oil at the supermarket yesterday. The supermarket is a 40 minute round trip which I'd like to avoid if possible. Any suggestions? I have eggs and Olivano spread if that helps….

then just use the olivano instead.
or an eggwhite based cookie like coconut macaroons

3 cups shredded coconut
4 large egg whites
1/2 cup sugar
1 teaspoon vanilla or almond extract (see Additional Notes)
1/4 teaspoon salt

Preheat the oven to 350°F. Place an oven rack in the bottom third of the oven and preheat to 350°F. Gather all your ingredients and equipment.
Toast the coconut (optional). For deeper coconut flavor and extra-crispy macaroons, spread the coconut on the baking sheet and toast for about 5 minutes, or until just barely starting to show some color. Let cool slightly before using.
Whisk the egg whites, sugar, vanilla, and salt. Combine the egg whites, sugar, vanilla, and salt in a mixing bowl. Whisk until the whites and sugar are completely combined and the mixture is frothy.
Combine the coconut and egg white mixture. Pour the coconut over the egg white mixture and stir until the coconut is evenly moistened.
Shape the macaroons. Line the baking sheet with a silpat or parchment. With wet hands to prevent sticking, shape the coconut mixture into small balls about 1 1/2-inches in diameter. Space them an inch or so apart on the baking sheet.
Bake the macaroons for 15-20 minutes. Bake the macaroons until golden, 15-20 minutes.
Cool the macaroons. Let the macaroons cool on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely.

I wasn't sure if the Olivano spread (lite I think) would have enough fat in it to use as a substitute?

won,t make much difference in a cake
