Ingredients You’ll Need for No Bake Peanut Butter Oat Cups

  • 1.5 cups peanut butter
  • 1.5 cups rolled oats (processed finely in a food processor to make oat flour)
  • 1/4 cup maple syrup
  • 1 cup chocolate chips
  • 1 tsp coconut oil (optional)

Let’s Make It Together

  1. Start by blending the rolled oats in a high-speed blender or food processor until it resembles a fine oat flour. This creates a wonderfully smooth base for your cups.

  2. In a medium-sized microwave-safe bowl, combine the peanut butter and maple syrup. Microwave for 40-60 seconds. Make sure to stir thoroughly until the peanut butter and maple syrup are completely combined into a creamy, luscious mixture.

  3. Gradually add the blended oat flour to the bowl and mix well. Don’t be shy; it will take some arm power to incorporate the oats! The mixture should be thick but moldable. If it seems too dry, add a teaspoon of maple syrup or peanut butter at a time for the right consistency. For a bit more moisture, consider mixing in 1/4 to 1/3 cup of pumpkin puree!

  4. Prepare your muffin pan by lining it with cupcake liners. Alternatively, feel free to use a silicone muffin pan, as shown in my photos; it makes for an effortless release! Note: It can be tricky to remove them from a metal muffin tin without liners.

  5. Scoop the peanut butter oat mixture evenly into the muffin pan, gently pressing down with your fingers to compact it well.

  6. In a microwave-safe small bowl, combine the chocolate chips and coconut oil. Melt them together in 30-second increments, stirring after each session until you achieve a smooth, glossy chocolate.

  7. Pour a layer of the melted chocolate over each muffin hole, smoothing the top with the back of a spoon. If you’re feeling extra fancy, sprinkle some flaky salt, colorful sprinkles, or mini chocolate chips on top before the chocolate hardens.

  8. Chill the muffin pan in the refrigerator for 2-3 hours to let the cups set completely. Once firm, carefully remove them from the muffin pan or silicone mold.

  9. Store the cups in an airtight container in the refrigerator for up to 5 days. Remember, since we’re using fresh ingredients like maple syrup, refrigeration is key to keeping them fresh.

Delicious Variations to Try

  • Nutty Delight: Add in some chopped nuts like almonds, or hazelnuts for a crunchy texture and nutty flavor.
  • Fruity Twist: Swirl in a few tablespoons of fruit preserves or add dried cranberries or raisins for a delightful burst.
  • Protein Power: Mix in a scoop of your favorite protein powder to turn your treat into a more wholesome snack option!
  • Chocolate Lovers: Use dark chocolate chips or swirl in some peanut butter chips along with your chocolate for double the indulgence!

Chef Emma’s Helpful Tips

  • Make-Ahead: These delightful cups are perfect for meal prep! Whip them up on a Sunday and enjoy all week long.
  • Swaps: Feel free to use almond butter instead of peanut butter for a deliciously creamy alternative!
  • Slicing: If you want to create bars instead of muffin cups, press the mixture into a square or rectangular baking dish lined with parchment paper.
