What is a Berry Crumble?

It’s that coveted time of year when gardens are bountiful and farmers markets are bursting with colorful produce. It’s simply the best. As a celebration of summer, you’ll find me making this low sugar berry crumble—on repeat. The ingredients are simple, and it packs an antioxidant punch. It’s the best of both worlds: the top is delicate yet crispy and the bottom is layered with seedy, juicy fruit. While this recipe calls for berries, peaches or nectarines would be lovely too! Ultimately, crumbles are very easy to make. A crumble is a baked dessert, made of fresh fruit with a streusel-like topping.

Ingredients in this low sugar berry crumble

Mixed berries

Think: blackberries, strawberries, raspberries, and blueberries. Pitted cherries work too!

granulated monk fruit sweetener

This is a low-glycemic sugar alternative (keeps blood sugar stable!). This is my favorite monk fruit for baking.

arrowroot powder

This is a thickening agent for the berry filling. I buy this arrowroot powder.

chia seeds

Chia seeds also act as a thickening agent. They’re rich in fiber and help balance blood sugar (as well as hormones!).

lemon juice

For acidity.

Almond flour

A gluten-free, grain-free flour that adds nuttiness and nourishing fats. I like to buy this brand in bulk and store it in the fridge.

rolled oats

Oats add chewiness to the otherwise crispy topping. Using these rolled oats keeps this recipe gluten-free.

shredded coconut

Mainly, for flavor and texture.

chopped almonds

For a bit of crunch on top!

maple syrup

My go-to unrefined sugar to add a note of sweetness for the crumble topping.

coconut oil

I love coconut oil’s subtle sweetness, but you can sub this for a 1:1 ratio of butter or ghee.

vanilla extract

The best flavor enhancer (other than sea salt!) in baked goods.


To add a hint of warmth.

sea salt

Brings out the crumble’s flavors.

Support your local farmers

Depending on where you live, you may be able to source your berries from local vendors. This retains their nutritional value, and supporting local farmers puts dollars back into your community’s economy. At any rate, berries are currently in season, so buying organic is cost-effective. Fresh or frozen berries work in this low-sugar berry crumble.
