The macaron cookie recipe is a classic, yet simple and the filling is chocolate ganache with strawberry jam in the middle.

Equipment
- Baking sheet
- Parchment paper or sil pat
- 2 Piping Bags
- Piping Tip 2A
- Standing Mixer w/whisk attachment
Ingredients
Ingredients for Cookies:
- 120 g egg whites room temp
- 200 g almond flour
- 60 g granulated sugar
- 200 g powdered sugar
- 1 teaspoon vanilla
- 1/4 teaspoon cream of tartar
- Food coloring optional
Ingredients for Ganache & Filling:
- 1 - 1.5 cups Reese’s peanut butter cup
- Strawberry jam
- 4 oz. any halloween chocolate ie: hershey’s
- 3/4 cup whipping cream
Instructions
For the Macaron Cookie:
- Preheat the oven to 300 degrees F (150 degrees C). Line two baking sheets with parchment paper.
- Sift together the almond flour and powdered sugar
- Using the standing mixer, whisk the egg whites until foamy. Then add the cream of tartar and VERY gradually add the sugar until stiff peaks form.
- Add the food coloring and vanilla to the egg white mixture, if desired.
- Gently fold the almond flour mixture, 1/3 at a time, into the egg white mixture until just combined. It should have a ribbon-like consistency.
- Transfer the macaron batter to a piping bag fitted with a medium round tip. Glue down the parchment paper to the sheet pan by piping a little bit of batter under the paper.
- Pipe the macaron batter onto the prepared baking sheets in 1” circles, spacing them about 1 inch apart.
- Tap the baking sheets on the counter a few times to remove any air bubbles.
- Let the macarons sit at room temperature for 30-40 minutes, or until they form a skin.
- Bake the macarons for 12-15 minutes, or until they are set and dry.
- Let the macarons cool completely on the baking sheets before removing them.
For the Reese’s Chocolate Ganache:
- Set the chocolate aside in a heat proof bowl (excluding the PB cups).
- Heat the heavy cream in the microwave until simmering, about 2-3 minutes.
- Slowly pour the warm heavy cream over the chocolate mixture and stir until smooth.
- Let it cool down slightly (for about 2-3 minutes), then add in the PB cups and peanut butter (optional). They should melt fairly quickly.
- Let it cool down further in the fridge (about 30 minutes to an hour) before adding to a piping bag with a medium piping tip of your choice.
For Assembly:
- To assemble the macarons, pipe the PB chocolate ganache in a circle (keep the middle empty) onto one macaron shell, so as to act as a dam for the jam. Dollop a small spoonful of jam in the middle and top with another macaron shell and gently press together.
- Repeat with the remaining macarons.
- Enjoy!
Notes
Tips & Notes:
- I tested with both 1” and 2” cookies, and highly recommend baking smaller cookies (ie: 1”) which are easier to handle once baked.
- My cookie batter ended up a little thicker than I’d like, so to avoid this, I recommend using the Blue Diamond or Trader Joe’s almond flour brands for a finer texture.
- For the best results, use superfine almond flour.
- Make sure the egg whites are at room temperature before starting and do not over whip into meringue (this can dry it out).
- If your batter becomes too thick, add 10 unbeaten grams of egg whites and judge from there if you need to add 5g more at a time after that.
- Don't overmix the macaron batter or it will become tough.
- Let the macarons sit at room temperature for 30 minutes before baking to form a skin/feet. This will help prevent them from cracking.
- Bake the macarons at a low temperature to prevent them from browning.
- Let the macarons cool completely before filling them.
