pumpkin seeds substitute
in cake.
Chopped Pumpkin Seeds in Cake add crunch and nutty richness to every slice. The substitute should toast well and hold up through the baking time.

adjustment for this dish
Sunflower seeds swap 1:1 cup for pumpkin seeds in cake. Chop to 3mm and toss in 1 tablespoon flour before the final fold — sunflower's oval shape suspends more evenly in the thin batter than pumpkin's flatter profile. Add 1/4 teaspoon extra baking powder per cup to offset fat weight so the tender crumb still rises within the 35-minute bake.

Hemp Seeds
10.0best for cake1 cup : 1 cup
Smaller but similar nutty flavor
10.0
adjustment for this dish
Hemp seeds are soft and dissolve into the aerated creaming structure, so the cake crumb becomes speckled green rather than pocketed with crunch. Swap 3/4 cup per 1 cup pumpkin seeds; no chopping needed since hemp is already small. Skip the flour toss and the extra baking powder — hemp doesn't sink and its weight is negligible.

Pecans
5.0best for cake1 cup : 1 cup
Nut-free, earthy flavor; toast until they pop
5.0
adjustment for this dish
Pecans are 72% fat (vs pumpkin's 45%) and their soft bite is lost in a tender aerated cake crumb. Chop to 3mm for 1:1 cup swap, toss in flour before the fold, and reduce recipe butter by 1 tablespoon to balance the fat load. Pecans release natural sugars that brown the crumb edges faster — check the toothpick at 32 minutes, not 35.

Pine Nuts
5.01 cup : 1 cup
Buttery seed for salads
5.0
adjustment for this dish
Pine nuts are softer than pumpkin seeds and lose their crunch identity in the cake's aerated crumb. Use 3/4 cup per 1 cup pumpkin seeds for comparable richness, chop to 3mm, and toss in flour before folding. Their 55% fat content can collapse the creaming structure if you skip the baking powder boost — sift in 1/4 teaspoon extra per cup of pine nuts.
05
Sesame Seeds
5.01 cup : 1 cup
Toasted for crunch on bread
5.0
adjustment for this dish
Sesame seeds weigh 1/10 of pumpkin seeds and won't sink through the thin cake batter, so skip the chopping and flour toss. Swap 1:1 cup but expect a nuttier, almost tahini-like crumb note after the 35-minute bake. Sift them through a fine mesh before folding to remove any dust that would bitter the tender crumb.

technique for cake
technique
5g weight each sinks through the thin batter and settles at the pan bottom during the 35-minute bake. Toss the chopped seeds in 1 tablespoon of the recipe's flour before the final fold — the coating grips the batter's structure and keeps them suspended until the crumb sets around the 18-minute mark.
Sift 1/4 teaspoon extra baking powder per cup of seeds to offset the fat weight; the tender crumb needs the extra lift to rise around the inclusions. Unlike brownies where whole seeds contribute textural contrast against a dense fudgy slab, cake requires chopped seeds because the aerated creaming structure can't support whole kernels without tearing.
And unlike muffins which dome upward in 18 minutes and trap seeds near the top, cake bakes flat and seeds distribute vertically — insert a toothpick at 32 minutes to check, since seed pockets retain moisture and read wet even when the crumb is done. Cool in the pan 10 minutes before turning out.
pitfalls to avoid
watch out
Don't fold whole seeds into cake batter; their 2.5g weight sinks through the thin batter before the crumb sets at 18 minutes — chop to 3mm first.
watch out
Avoid skipping the flour toss on chopped seeds; without it the creaming structure can't suspend them and you get a seed layer at the pan bottom.
watch out
Don't rely on the toothpick test in a seed pocket — moisture from seed fat reads wet even when the tender crumb is done; test 1 inch from the edge instead.
watch out
Skip the extra baking powder boost (1/4 tsp per cup of seeds) and the cake rises short, since seed fat weighs down the aerated whisk structure.
watch out
Don't turn the cake out of the pan before 10 minutes of cooling — seed-laden crumb is fragile until the starch retrogrades and the structure sets.
