I’ve been eating a lot of protein breakfasts lately, and these PB&J protein breakfast crumbles might just be my favorite. It’s like a warm berry crisp and peanut butter oat bar packed with protein. It’s basically hassle-free and ready in 40 minutes.
This protein berry crumble layers chia seeds and frozen mixed berries under a buttery peanut butter-oat crumble with vanilla protein powder. It’s warm, jammy, and tastes like PB&J in crumble form. It’s great for breakfast due to the added protein. All you need is 6 ingredients and 1 pan.
Why You’ll Love This Protein Berry Crumble
- 6 Ingredients, 1 Pan: Frozen berries, chia seeds, peanut butter, oats, maple syrup, protein powder. That’s it. No butter, no flour, no eggs.
- It tastes like dessert and is eaten like breakfast. The PB&J flavor combination is nostalgic and satisfying. But protein powder and chia seeds really fill you up.
- Easy to prepare meals: Make it on Sunday and reheat it throughout the week. Once the berries have infused the crumble, it reheats beautifully the next day and tastes even better.
- Endlessly customizable: Switch up the nut butter, switch up the berries, and drizzle over yogurt. This recipe is a template you will use all season long.
main ingredients
- Frozen Mixed Berries: The jammy base of this crumble. No need to defrost. It goes right into the pan and decomposes beautifully in the oven. I like to mix strawberries, blueberries, and raspberries for the best PB&J flavor.
- Chia Seeds: When mixed into the berry layer, it absorbs the fruit juices and thickens everything into a jam-like filling that you can eat with a spoon. It’s almost like a natural fruit compote.
- Thin Peanut Butter: The epitome of crumble topping. It should be naturally runny (not stiff) so it can mix smoothly with the oats and protein powder. If the container is thick, warm it in the microwave for 20 seconds first.
- Quick-cooking oats: They give the crumble a golden color, crumbly feel and slightly chewy texture. Quick oats work better than rolled ones here because they combine more evenly with the peanut butter.
- Vanilla Whey Protein Powder: Adds protein to the crumble topping without changing the taste or texture. I use Teras Whey, but any vanilla protein powder you like will work. Check out my guide to the best protein powders for recommendations.
- maple syrup: Just enough sweetness to balance out the tart berries. Honey also works, but watch it carefully. Honey browns faster in the oven.
How to Crumble Protein Berry
Full instructions are in the recipe card below, but here’s a quick overview:
- Prepare the berry base: Place frozen mixed berries and chia seeds in a greased 8×8 inch pan.
- Making it fall apart: Mix peanut butter, oats, maple syrup, and protein powder until a crumbly topping forms.
- baking: Sprinkle the crumble over the berries and bake at 350°F for 25 to 35 minutes, until the berries are bubbling and the crumble is golden.
- Cool and awesome: Let sit for 10 minutes, then sprinkle with extra peanut butter and jam.
Top Tips
Use dripping peanut butter: Hard, dry peanut butter does not combine well with oats and protein powder. If your jar is thick, microwave it for 20 to 30 seconds until pourable.
Do not thaw the fruit: Frozen berries go straight into the pan. If you thaw it first, too much liquid will come out and the filling will feel more like broth than jam.
Look at the crumble color. The peanut butter-oat topping can quickly darken from golden in color after 25 minutes. Start checking after about 25 minutes and pull when bubbles appear around the edges of the fruit and the crumble turns light brown.
Heat the drizzle topping. For the prettiest finish, heat the peanut butter until it’s thick enough to drizzle. Adding a little water to the jam will loosen it up and give you a nice ribbon effect.
- Nut Butter Swap: Almond butter, cashew butter, or sunflower seed butter (if nut-free) all work in the crumble.
- Single berry version: For a more concentrated flavor, use only blueberries, only strawberries, or only raspberries.
- Chocolate PB Twist: To make chocolate peanut butter berry crumbles, use chocolate protein powder instead of vanilla.
- Plant-based version: Swap out the whey for your favorite plant-based vanilla protein powder. The texture remains the same.
- Serve over yogurt: Add some warm crumbles to a bowl of cottage cheese or Greek yogurt for a boost of protein.
refrigerator: Store leftovers in an airtight container for up to 5 days. Heat individual portions in the microwave for 60 to 90 seconds.
Freezer: Wrap individual portions tightly in plastic wrap and store in a freezer bag for up to 2 months. Thaw overnight in the refrigerator and then reheat in the microwave.
More High-Protein Breakfast Recipes
Yes, but frozen berries work better here. When roasted, more juices are released and a thick, jam-like filling is created. The fresh berries still taste good, but the filling isn’t as tasty. Add another tablespoon of water to replenish.
I use Teras Whey vanilla protein powder, but vanilla whey or plant-based protein powder would also work. Avoid blends high in casein. This can make the crumble too dense and dry. The crumble should feel slightly sandy and lumpy when mixed, not wet.
The chia seeds absorb the berry juices as the crumble bakes, thickening the filling and giving it a spoonable texture rather than a watery consistency. It also adds fiber and omega-3s. Don’t skip it. Without the chia seeds, the berry layer would remain too liquid.
yes! Honey acts as a 1:1 exchange with maple syrup. Keep an eye on the crumbles in the oven. Honey browns faster than maple syrup, so you may need to take it out a few minutes earlier to prevent excessive browning.
I like it straight from the pan with warm peanut butter and jam on top. Top it with Greek yogurt or cottage cheese for an extra dose of protein. It’s also great as a dessert with a scoop of vanilla ice cream.
Preheat oven to 350°F (175°C). Lightly coat an 8×8 inch baking dish with cooking spray.
Add frozen mixed berries and chia seeds to baking dish. Mix and spread in an even layer.
In a medium bowl, combine peanut butter, quick-cooking oats, maple syrup, and vanilla protein powder. Stir until a crumbly mixture forms. If the peanut butter is too hard to mix, microwave it for 20 seconds first.
Sprinkle the crumble topping evenly over the berry layer. Do not press. For the best texture, you want it to be loose and crumbly.
Bake for 25 to 35 minutes, until the berries are bubbling around the edges and the crumble topping is golden brown. Start checking at 25 minutes.
Let the crumble cool for 10 minutes. Sprinkle with melted peanut butter and jam and serve warm.
Freezer Friendly: Wrap portions tightly and freeze for up to 2 months.
Nut Butter Swap: Almond butter, cashew butter, and sunflower seed butter all work.
Protein Powder: Any vanilla whey or plant-based protein powder will work.
sweetener: Honey works 1:1 with maple syrup, but turns brown faster.
