Ingredients Overview

Each layer is made with pantry staples that bring flavor, nutrition, and texture without needing to turn on the oven.

Rolled Oats

The base of the oat cup, providing chewiness and whole grain goodness.

• Use old-fashioned rolled oats (not instant or steel-cut).

• For smoother texture, you can pulse oats slightly in a food processor.

Peanut Butter

The star ingredient — creamy, salty-sweet, and protein-packed.

• Natural peanut butter (just peanuts + salt) works best.

• Crunchy peanut butter adds texture, if preferred.

Allergy-Friendly Option: Use almond butter, sunflower seed butter, or cashew butter.

Maple Syrup or Honey

Binds the oats and adds natural sweetness.

• Maple syrup gives a deeper, caramel-like sweetness.

• Honey adds floral notes and thicker consistency.

Coconut Oil (Optional)

Helps firm up the cups and improves texture, especially in warm weather.

• Adds a touch of richness without overpowering.

• Can be omitted if you chill the cups thoroughly.

Chocolate (Optional Topping)

Adds a decadent, dessert-like finish.

• Use dark, milk, or dairy-free chocolate chips.

• Add a splash of coconut oil when melting for a smoother, snappier finish.

Sea Salt (Optional)

Sprinkle on top to contrast the sweetness and bring out flavor.

Step-by-Step Instructions

1. Make the Oat Base

In a mixing bowl, stir together:

• 1 ½ cups rolled oats

• ½ cup peanut butter

• ¼ cup maple syrup or honey

• 2 tbsp melted coconut oil (optional)

• ½ tsp vanilla extract

• Pinch of salt

Mix until a sticky dough forms. If it’s too dry, add a little more peanut butter or syrup. If too wet, stir in more oats.

2. Press Into Muffin Tin

Line a 12-cup muffin pan with silicone liners or paper liners.

Divide the oat mixture evenly among the cups (about 1 heaping tablespoon per cup). Press firmly into the bottom using a spoon or your fingers.

Tip: Dampen your fingers slightly to prevent sticking.

3. Add Peanut Butter Layer

Scoop about 1 teaspoon of peanut butter onto each oat base and spread it gently to cover. This becomes the gooey center.

Optional: Mix a little maple syrup into the peanut butter if you prefer it slightly sweetened.

4. Add Chocolate Topping (Optional)

In a small bowl, melt:

• ½ cup chocolate chips

• 1 tsp coconut oil (optional)

Stir until smooth, then spoon over the peanut butter layer.

Sprinkle with flaky sea salt or crushed peanuts if desired.

5. Chill and Set

Place the muffin tin in the fridge for at least 1 hour, or freeze for 20–30 minutes, until firm.

Once set, remove from liners and store in an airtight container in the fridge or freezer.

Tips, Variations & Substitutions

• Nut-Free Version: Use sunflower seed butter and allergen-free chocolate.

• Add Crunch: Mix in chopped peanuts, puffed rice, or chia seeds to the oat base.

• Make it Protein-Packed: Stir in 1–2 scoops of vanilla or unflavored protein powder into the oat layer.

• Flavor Twist: Add cinnamon, cocoa powder, or espresso powder to the oat mixture for extra depth.

• Lower Sugar: Use unsweetened peanut butter and reduce maple syrup. Add stevia or monk fruit sweetener if desired.

FAQs

Q1: Can I freeze these oat cups?
Yes! They freeze beautifully. Store in a sealed container for up to 2 months. Let thaw at room temperature or eat straight from the freezer.

Q2: Can I make these without chocolate?
Absolutely. They’re still delicious without the topping — just peanut butter and oats is enough for a great snack.

Use natural peanut butter, and don’t over-chill the cups. You can microwave for 5–10 seconds to soften before eating.

Q4: Can I use instant oats?
You can, but the texture will be softer. Rolled oats give the best chewy consistency.

They’ll keep for up to 7–10 days in an airtight container in the fridge.

Add protein powder or a spoonful of hemp seeds, chia seeds, or collagen peptides to the oat mixture.
